Bapu Studio – Open-Source Client for APIs, Databases, and Secrets

Bapu Studio, an open-source desktop application combining an API client, database studio, and secrets manager, has been released under the AGPLv3 license. The Electron-based tool supports REST, GraphQL, Postgres, MySQL, MongoDB, and SQLite, with 100% local storage and zero telemetry. Its AI Copilot is currently a local heuristic engine with no live LLM integration, though provider options for Ollama, OpenAI, and Anthropic are planned.

The honest, lightweight, local-first developer cockpit combining an API Client, Database Studio, and Secrets Matrix into one seamless desktop application. 📦 Downloads -downloads • 🌐 Live Website https://joravar.github.io/bapu-studio/ • 🏗️ Architecture %EF%B8%8F-architecture--technology-stack • 🤖 AI Copilot -ai-copilot--current-status • 💖 Sponsor -support--github-sponsors • 📄 License -license Developers are tired of running several heavy apps just to test an endpoint, run a database query, and check a .env secret. Bapu Studio stands for simplicity, truth, zero bloat, and complete local privacy . ┌────────────────────────────────────────────────────────────────────────┐ │ BAPU STUDIO │ ├───────────────────────┬────────────────────────┬───────────────────────┤ │ 🚀 API CLIENT │ 🗄️ DATABASE STUDIO │ 🔐 SECRETS MATRIX │ │ • REST, GraphQL │ • Postgres, MySQL │ • Scoped .env Matrix │ │ • Latency & Headers │ • MongoDB & SQLite │ • Variable Inject │ │ • cURL Import/Export │ • Dynamic Table Grid │ • Secret Masking │ └───────────────────────┴────────────────────────┴───────────────────────┘ Direct native installer packages are available on GitHub Releases https://github.com/joravar/bapu-studio/releases/tag/v1.0.0 : | Operating System | Installer Package | Format | |---|---|---| 🪟 Windows | Download Windows Installer | .exe NSIS & Portable 🍏 macOS Apple Silicon Download macOS DMG .dmg & .zip | Feature | Postman | TablePlus | DBeaver CE | Bapu Studio OSS | |---|---|---|---|---| Runtime | Electron + Chromium | Native | JVM bundled Java | Electron no JVM | Idle RAM | Widely reported in the hundreds of MB, climbing over long sessions | Generally light — native app | Can run heavy due to JVM overhead | Lean by design — no JVM, minimal UI framework | 100% Offline-First | ❌ Forced Cloud | ✅ | ✅ | ✅ 100% Local Storage | Unified DB + API + Secrets | ❌ | ❌ | ❌ | ✅ All-in-One | Pre-Bundled Drivers | ❌ None | ✅ Most JDBC | ✅ Postgres, MySQL, Mongo, SQLite | | Telemetry / Data Privacy | Cloud sync by default | Closed source, local | Open source, local | 100% Zero Telemetry | License | Proprietary $$$ | Proprietary | Open Source Apache 2.0 | Open Source AGPLv3 | - Node.js v18+ 1.

Launch native desktop application npm run desktop Desktop Engine: Electron runtime with bundled pure-JS TCP drivers pg , mysql2 , mongodb , sql.js . Frontend Cockpit: React 18 / TypeScript with Vite compiler. Design System: Tailored HSL Dark Theme Vanilla CSS Zero CSS framework bloat . Storage Engine: 100% local persistence across cold boots. The AI Copilot panel available in both API Studio and Database Studio ships today as a local, fully offline heuristic engine . It pattern-matches your prompt against a small set of built-in SQL and JSON templates and returns a result instantly — no network call is made, which is why it's genuinely zero-telemetry: there's nothing to transmit yet. The provider selector Local Ollama / OpenAI BYOK / Anthropic BYOK and API key field are present in the UI ahead of real model-backed generation, which is still on the roadmap. Selecting a provider or entering a key does not currently change the output — treat the Copilot as a smart snippet generator for now, not a live LLM integration. We'd rather say this plainly here than have it be a surprise. If you want to help wire up real Ollama/OpenAI/Anthropic calls, contributions are welcome.
