📌

Hey Product Hunt! 👋 I'm Brooke, founder of AFaaS. Last year my security team blocked my AI assistant from accessing my Obsidian vault: "Data leaves our infrastructure. We can't allow that." Sound familiar? Every mainstream AI integration sends your data to someone else's servers. For regulated industries (finance, healthcare, defense, government), that's a hard no. So I built three MCP servers that run entirely on your machine: 🔐 vault-bridge — Obsidian vault (read/write/search, frontmatter, daily notes, stateless protocol) 📁 airgap-file-bridge — Filesystem (ripgrep search, atomic writes, symlink protection, stdio/SSE/HTTP) 🐘 airgap-db-bridge — PostgreSQL (parameterized queries = SQLi prevention, read-only mode, audit logs, stateless) All three: pip install vault-bridge airgap-file-bridge airgap-db-bridge Standard MCP protocol → works with Claude Desktop, Cursor, VS Code uvx airgap-file-bridge /tmp for zero-install demo MIT licensed, 155 tests passing, CI/CD green Published on PyPI (test + production) Why this exists: Your data, your rules. Zero data egress. Works offline. Works in air-gapped environments. No vendor lock-in. Built for developers who want AI with local data, security teams blocking cloud AI, and enterprises with SOC2/HIPAA/ITAR/GDPR requirements. Happy to answer questions about architecture, security model, or MCP protocol implementation! Links: GitHub: Airgap Fleet · GitHub PyPI: vault-bridge, airgap-file-bridge, airgap-db-bridge Docs: README in each repo Try it: pip install vault-bridge airgap-file-bridge airgap-db-bridge What would you connect first — your vault, files, or database? 👇

The State of Open Source 2025 - Key Takeaways

GitHub recently published this year's Octoverse, the state of the open-source ecosystem.

Below are my key takeaways:

AI doesn't replace developers - it brings more people into the ecosystem. A new developer joined GitHub every second in 2025. Top 5 developer populations: 1. United States, 2. India, 3. China, 4. Brazil, 5. United Kingdom.
Open source remains the foundation. Fastest-growing OSS projects by contributors include @Zen Browser, @VS Code, and AI-focused @Continue.
TypeScript is now the most used language on GitHub, overtook both Python and JavaScript. The AI effect? 80% of new repositories used just six languages: Python, JavaScript, TypeScript, Java, C++, and C#.
Gen AI is now standard in development. 1.1M public repositories now use an LLM SDK.
Agents are here. Coding agents created 1M+ pull requests (PR) in the last 6 months, and it's just getting started.
