Since launching our own product line in April 2025, we have shipped 15+ products spanning SaaS platforms, AI-powered tools, browser extensions, desktop and iOS applications, Stream Deck plugins, and complex backend systems. Our engineering approach is product-first: every technical decision is driven by product goals, not architecture diagrams. We use AI to ship faster without cutting corners. Important architecture decisions are backed by research and deliberate trade-off analysis, not guesswork. We deliver polished, tested, production-ready products - not half-finished handoffs. ## Products ### TUGANQ - Legal Reference Portal - URL: https://tuganq.com/en - Category: Legal Reference Portal - Platform: Web App - Pricing: Free - Status: live - Tech: Next.js, JavaScript - Target audience: Drivers, vehicle owners, legal professionals, and expats in Armenia who need clear, multilingual access to traffic laws, fines, and administrative procedures. - Highlights: 3 Languages, 10 Legal Categories, Extensive Article Library, 2026 Updated - Description: Armenia's legal information is scattered across dozens of government websites, buried in dense legal language, and almost never available in multiple languages. TUGANQ changes that. It's a structured, searchable legal reference portal that started with traffic fines and state duties and now spans ten categories - patrol, police, municipality, the State Revenue Committee, compulsory enforcement, MTPL insurance, the courts, property law, and general legal reference - all in Armenian, Russian, and English. Whether you're a driver checking a fine, a lawyer researching a procedure, or an expat navigating Armenian bureaucracy, TUGANQ gives you clear, actionable answers instead of legal jargon. ### CoPilly - Chrome Extension - URL: https://copilly.com - Category: Chrome Extension - Platform: Browser Extension - Pricing: Paid - Status: live - Tech: React, TypeScript, Python, AI, Chrome - Target audience: Sales professionals, startup founders, recruiters, job seekers, and anyone building a personal brand on LinkedIn who wants to scale engagement without risking their account. - Highlights: Context Aware AI, Instant Generation, Zero Automation, 3 Tone Options - Description: Most LinkedIn AI tools use automation that violates LinkedIn's Terms of Service - one update and your account is gone. CoPilly takes a fundamentally different approach. It's a Chrome extension that generates context-aware comments, DM replies, and connection invites through a manual right-click workflow. The AI reads the actual post context and adapts to your personal tone, but you always trigger and review before posting. The result: engagement that takes seconds instead of minutes, with zero risk of account bans. Used by sales teams, founders, and recruiters who value their professional network too much to gamble it on automation bots. ### CleanyAI - Text Tool - URL: https://cleanyai.com/en/ - Category: Text Tool - Platform: Web App - Pricing: Free - Status: live - Tech: Next.js, JavaScript - Target audience: Content creators, copywriters, editors, marketers, and anyone who regularly copies text from AI tools and needs it clean for publishing or professional use. - Highlights: Instant Processing, 100% Private, Free No Sign-Up, 7 AI Models - Description: Every AI model outputs text littered with Markdown headers, bold tags, code blocks, and bullet formatting that breaks when you paste it into emails, documents, or CMS platforms. CleanyAI strips all of it instantly. Paste any AI-generated text - from ChatGPT, Claude, Gemini, Grok, Copilot, or DeepSeek - and get clean, publication-ready output instantly. All processing happens locally in your browser. No data is stored, no sign-up required, no limits. Built for content creators, writers, and marketing teams who paste AI output every day. ### YouTube Hide Watched - Browser Extension - URL: https://chromewebstore.google.com/detail/apijflcddkipimiehadinhecdinnjgpn - Category: Browser Extension - Platform: Browser Extension - Pricing: Free - Status: live - Tech: Chrome, JavaScript - Target audience: YouTube power users, content enthusiasts, and anyone frustrated by YouTube's tendency to resurface already-watched videos in recommendations and search results. - Highlights: 3 Modes: show, dim, hide, 6 Sections tuned apart, 12 Languages, Local Nothing leaves the browser - Description: YouTube's algorithm loves showing you the same videos you have already watched. YouTube Hide Watched takes them out of the way - and lets you decide how. Each video can be shown normally, dimmed to a whisper, or hidden outright, and you set that independently for the home page, subscriptions, channel pages, the watch-page sidebar, trending, and playlists, with Shorts handled on their own. A watch threshold decides how much of a video counts as watched, an eye icon on any thumbnail hides or dims that one video on the spot, and everything you have hidden by hand lives in a manager page you can search, filter, page through, and export or import as a backup. It speaks twelve languages, follows your system's light or dark theme, and keeps every setting in your own browser - nothing is sent anywhere. ### Mac Bluetooth - Stream Deck Plugin - URL: https://marketplace.elgato.com/product/mac-bluetooth-pro-a2c03e1c-e3fc-448e-8235-c2a33d097c84 - Category: Stream Deck Plugin - Platform: Stream Deck Plugin - Pricing: Free core, paid Pro - Status: live - Tech: TypeScript, Swift, macOS - Target audience: Content creators, podcasters, streamers, and Mac power users with an Elgato Stream Deck who switch Bluetooth devices and audio routing throughout the day. - Highlights: 9 Actions on keys, Audio Output, input, mute, Swift IOBluetooth + CoreAudio, Free + Pro Editions - Description: Switching Bluetooth devices on macOS means clicking through System Settings, finding the device, waiting for the list to load, and clicking Connect - every single time. Mac Bluetooth brings that down to one key press. The free edition covers the three essentials: toggle a paired device, toggle the Bluetooth radio, and read a device's battery level, each key following the real system state. Mac Bluetooth Pro adds six more actions - switch the Mac's sound output or input through CoreAudio, mute the system microphone with an audible confirmation, run a multi-step Device Scene, swap between two devices with one key, and browse paired devices on a Stream Deck + dial - plus a low-battery alert, a keep-connected watchdog, and battery drawn straight on the key. Every system operation goes through a Swift helper talking to IOBluetooth and CoreAudio directly. macOS 13 or later, Stream Deck app 6.9 or later. ### FileWarden - Atlassian Forge App - URL: https://kuberstar.com/products/filewarden - Download: https://marketplace.atlassian.com/apps/921894309/filewarden-attachment-governance-for-jira - Category: Atlassian Forge App - Platform: Jira App - Pricing: Free core, paid Pro - Status: live - Tech: JavaScript, Forge - Target audience: Jira Cloud admins and compliance teams who need to control which file types can be attached to issues, catch leaked secrets and PII, and prove it all with an audit trail. - Highlights: Every upload path Coverage, Secret + PII scan Content DLP, CSV audit log Compliance, 100% on Atlassian No external egress - Description: FileWarden is an Atlassian Forge app that governs attachments across every Jira upload path - comments, descriptions, forms, custom fields, and Jira Service Management requests - and blocks executables on Confluence pages and blogs, moving them to Space Trash. Set one allowlist or blocklist by extension, MIME type, filename pattern, or maximum size, or apply a one-click compliance template (block executables, block secrets, HIPAA, PCI-DSS, GDPR, or office-only). The moment a violation lands, FileWarden removes it - or quarantines it on Pro - and posts a clear comment naming the policy it broke. On Pro, a content scan reads inside text, PDF, Word, Excel, and PowerPoint files for leaked secrets and PII - AWS keys, private keys, GitHub, Slack and Google tokens, JWTs, credit cards, US SSNs, and IBANs - and a signature check catches a blocked type renamed to slip past its extension; the matched value is never shown or logged, and there is no antivirus engine and no OCR. Beyond file type, it caps how many attachments an issue may hold and blocks duplicates by filename or by byte-identical content, and a workflow validator can stop a transition while a disallowed file is still attached. Monitor mode lets you prove a policy before you enforce it, a grace period and trusted uploader exemptions soften the rollout, and every action is logged newest-first and, on Pro, exports to CSV for auditors. It runs entirely on Atlassian with zero external egress. ### Pixrim - iOS App - URL: https://kuberstar.com/products/pixrim - Download: https://apps.apple.com/app/id6771029149 - Category: iOS App - Platform: iOS App - Pricing: Free core, paid Pro - Status: live - Tech: Swift, SwiftUI, iOS - Highlights: On-device Privacy, 8 formats + PDF Both directions, Offline Works fully, Free Core tools - Description: Pixrim is a fast, private image toolkit for iPhone and iPad. Convert between HEIC, JPG, JPEG, PNG, WebP, AVIF, TIFF and BMP, turn photos into a single multi-page PDF, or open a PDF and turn its pages back into images. Compress to save space, resize to exact dimensions, crop, add a text or logo watermark, and set the DPI for printing - and run any of it over a whole batch, or straight from the share sheet in another app. Every operation runs on-device with Apple frameworks, so your photos never leave your device. It ships localized in more than 30 languages and requires iOS 17 or later. The core tools are free; Pixrim Pro - a one-time purchase or a yearly subscription - unlocks every format and removes limits. ### Estimaid - iOS App - URL: https://kuberstar.com/products/estimaid - Download: https://apps.apple.com/app/id6777764178 - Category: iOS App - Platform: iOS App - Pricing: Free core, paid Pro - Status: live - Tech: Swift, SwiftUI, SwiftData, iOS - Target audience: Cleaning contractors use the app; this record exists for teams evaluating KUBERSTAR for native iOS work. - Highlights: Offline Core flow needs no network, 34 Translated locales, 485 Test cases in the suite, End to end Design, build, release - Description: Estimaid is our own iOS product and the studio's reference case study for native Apple work. The app opens a local SwiftData store on device and treats CloudKit as a mirror, so the whole quoting flow works without a signal; its price breakdown is a pure, nonisolated function whose result is frozen onto each saved job, so editing a rate card later cannot rewrite a number a client already agreed to. Around that sit a WidgetKit extension fed by an App Group snapshot file rather than the app's store, StoreKit purchases with an on-device entitlement cache, an analytics spool that survives the app being swiped away, and a localization gate covering 34 translated locales that measures label widths in points rather than characters. ### ToolboxLog - iOS App - URL: https://toolboxlog.com - Download: https://apps.apple.com/app/id6798291794 - Category: iOS App - Platform: iOS App - Pricing: Paid - Status: live - Tech: Swift, SwiftUI, SwiftData, iOS - Target audience: Foremen and 5-50 person trade contractors keep the records; this record exists for teams evaluating KUBERSTAR for native iOS work. - Highlights: 132 Talks, each with its citation, Offline No account, no server on the path, EN + ES Both halves of the crew, 277 Test cases in the suite - Description: ToolboxLog is our own iOS product, built for foremen and small trade contractors who are on the hook for a safety record they currently keep on paper. The app ships a library of 132 toolbox talks across 22 hazard categories, every one of them carrying the citation it was written from, in English and Spanish; it captures attendance and a finger signature per crew member on the phone, and renders the meeting as a PDF on device. The whole flow is built to run at 6:45am in a basement or past the last cell tower: a local SwiftData store, no account, no login, and no network call anywhere on the path from opening a talk to holding the signed document. It also encodes the meeting-cadence and record-retention rules for California, Oregon and Washington, each with the regulation it comes from, so the app can say when the next talk is due rather than leaving that to memory. ### Qartez - Developer Tool - URL: https://qartez.dev - Source: https://github.com/kuberstar/qartez-mcp - Category: Developer Tool - Platform: Developer Tool - Pricing: Free for individuals and small teams, commercial licence above - Status: live - Tech: Rust, AI, macOS, Linux, Windows - Target audience: Developers and teams using AI coding agents who want faster, cheaper, and safer code intelligence on large or unfamiliar codebases. - Highlights: 40+ MCP tools, Graph-aware Index, Local-first No cloud, Source-available Core server - Description: Qartez gives AI coding assistants a real understanding of a codebase. It is a Rust MCP (Model Context Protocol) server that builds a language-aware index and replaces naive file search with structured tools: jump to any symbol, trace call hierarchies, measure the blast radius of a change before editing, and run guarded refactors. The core server is source-available: free for individuals and small teams, with a commercial licence for larger companies and a hosted offering at qartez.dev. ### GPT Deck - Stream Deck Plugin - URL: https://marketplace.elgato.com/product/gpt-deck-pro-9c339c86-922c-43c3-9af6-879255edc6c4 - Category: Stream Deck Plugin - Platform: Stream Deck Plugin - Pricing: Free core, paid Pro - Status: live - Tech: TypeScript, AI, macOS, Windows - Target audience: Stream Deck owners who use ChatGPT daily and want their most-used prompts one key press away, without copy-paste friction. - Highlights: One key To ChatGPT, 4 Free preset keys, 3 Delivery modes, No API key Uses your ChatGPT - Description: GPT Deck turns Stream Deck keys into one-tap ChatGPT shortcuts. GPT Deck Lite (free) ships four fixed-purpose preset keys - Translate, Summarize, Fix Grammar, and Explain - with locked prompts, delivered through your browser with no API key required, plus an experimental mode that drives the ChatGPT desktop app. GPT Deck Pro adds the fully customizable Ask ChatGPT key, editable prompts on every key, reply-back to your clipboard, OpenAI API mode, model switching, background sending, interactive fill-in prompts, and a Self-check diagnostic key. It runs on macOS 13+ and Windows 10+ with the Stream Deck app 6.9 or later. ### Notion Deck - Stream Deck Plugin - URL: https://marketplace.elgato.com/product/notion-deck-pro-3d8efb3d-96d2-4302-b2aa-6ac3c1794c17 - Category: Stream Deck Plugin - Platform: Stream Deck Plugin - Pricing: Free core, paid Pro - Status: live - Tech: TypeScript, macOS, Windows - Target audience: Notion power users with a Stream Deck who want their daily capture, navigation, and tracking rituals on physical keys instead of buried in menus. - Highlights: 13 Single-tap actions, 1 tap No modals, Live Inbox counts, Free + Pro Editions - Description: Notion Deck brings Notion to physical Stream Deck buttons: capture straight into any database, jump around your workspace, and watch live record counts update on the keys - no modals, no Cmd+J. It is built around a multi-database capture grid, the piece no other Notion plugin on the Elgato Marketplace offers. ### Burndown - Stream Deck Plugin - URL: https://marketplace.elgato.com/product/burndown-pro-ai-usage-monitor-62c48df2-83ee-4196-a832-d156195fdb40 - Category: Stream Deck Plugin - Platform: Stream Deck Plugin - Pricing: Free core, paid Pro - Status: live - Tech: TypeScript, AI, macOS, Windows - Target audience: Claude power users who live in Claude all day and want their usage windows on a physical key instead of a browser tab. - Highlights: 5h + 7d Windows tracked, 11 Actions on keys, Lockout clock When you run out, Free + Pro Editions - Description: Burndown keeps your Claude usage in view without a browser tab. The free edition puts your 5-hour and 7-day windows on the key - percent used, time to reset, and a sustainable pace - with severity colors shifting green to yellow to orange to red. Burndown Pro adds a lockout clock projecting when you will actually run out, a reset forecast, a usage sparkline, weekly stats, a personal budget plan, and native notifications, and on multi-account setups tells you which account has the most headroom right now.

The free Lite edition covers the five everyday essentials - Eject All, Sleep, Wi-Fi, Volume, and Clear Clipboard - and needs no permission prompts at all. Mac Control Pro adds twenty more: live-state toggles for Dark Mode, Desktop Icons, Hidden Files, Dock Auto-hide, and Stage Manager; one-press Lock Screen, Empty Trash, Display Off, Screenshot, Keep Awake, and Mic Mute; five window-management actions; and Vision capture that picks a screen colour as hex, OCRs a region, or scans a QR code straight to your clipboard.

KUBERSTAR builds websites and web apps, SaaS platforms, AI tools and assistants, browser extensions, desktop applications, client portals, automation systems, backend architectures, data pipelines, internal tools, and production-grade infrastructure. We cover the full spectrum, from polished user-facing interfaces to deep backend engineering and DevOps. ### Does KUBERSTAR build its own products or only client work? KUBERSTAR was founded in November 2022. Since launching our own product line in April 2025, we have shipped 15+ digital products - SaaS platforms, AI tools, browser extensions, and desktop apps. Building our own is how we sharpen the craft and prove our engineering, and it is why we build better products for the companies we partner with. ### What technologies does KUBERSTAR use? Our core stack is TypeScript, Rust, Python, Go, and JavaScript. On the frontend we use Next.js, React, Svelte, and TailwindCSS. On the backend, production-grade frameworks across Rust, Python, and Node.js. For desktop, Tauri and Electron. For DevOps and infrastructure, Docker, Kubernetes, and Linux. We pick the right tool for each job - strong opinions, loosely held. ### What is KUBERSTAR's development process? We work in four phases. Discover: understand your product, goals, users, and technical landscape. Design: shape the product with architecture, UX, and technical decisions settled upfront. Build: ship fast on a modern stack with an AI-assisted workflow. Launch: polished, tested, deployed - a real product, ready for users. ### How does KUBERSTAR price projects? Pricing depends on the project's type, scope, and timeline. The fastest way to a number is the guided brief at kuberstar.com/start - tell us what you want to build, your scope, budget, and timeline, and it reaches our team directly. We then start with a Discover phase to understand your goals before we scope the work. ### Do you work fixed-price or on retainer? Both. As a product and engineering studio, we shape the engagement around the work - a defined scope can be quoted as a fixed-price build, while ongoing product development fits an ongoing arrangement. Share your project type, scope, and timeline through the brief at kuberstar.com/start and we will recommend the right model. ### Do you sign NDAs? Yes. We are happy to sign an NDA before getting into the specifics of your project. Mention it in your brief at kuberstar.com/start or email hello@kuberstar.com, and we will sort it out before the Discover phase. ### How can I start a project with KUBERSTAR? The fastest way is the guided brief at kuberstar.com/start - tell us your project type, scope, budget, and timeline, and it reaches our team directly. Prefer email? Reach us at hello@kuberstar.com. Either way, we start with the Discover phase to understand your goals and define what success looks like. ## Why KUBERSTAR - We build our own products: 15+ own products shipped since April 2025. We understand what it takes because we do it ourselves - every day. - Product-first thinking: Every technical decision is driven by product goals. We build for users, not for architecture diagrams. - Engineering depth: From polished UIs to complex backend pipelines, data processing systems, and automation workflows. - AI-assisted speed: AI is integrated into our development workflow to ship faster without cutting corners - not bolted on as a marketing checkbox. - Research-driven execution: Important architecture decisions are backed by research and deliberate trade-off analysis, not guesswork. - Launch-ready delivery: We don't hand off half-finished projects. We deliver polished, tested, production-ready products. ## Contact Email: hello@kuberstar.com Website: https://kuberstar.com ## Product Support Support for every KUBERSTAR product is handled on one page: https://kuberstar.com/support Support email: support@kuberstar.com - email-based, 24-hour initial response, Monday to Friday 09:00-18:00 Asia/Yerevan (excluding public holidays).
