Engineering Open Tools for the Local-First Web.
We build and maintain open-source developer toolkits, cross-platform desktop architectures, and privacy-respecting AI companions. No telemetry, no vendor lock-in — complete source transparency.
100% Local-First Privacy
All data remains on the user's device in SQLite. Zero cloud telemetry.
Propose-Then-Approve Safety
AI agents cannot mutate databases without interactive 60s human approval.
MIT Permissive License
Fork, audit, extend, or redistribute without proprietary restrictions.
Zero Vendor Lock-In
No SaaS subscriptions, no analytics tracking, complete source transparency.
Active Open Source Projects
Explore in-depth architectural guides, API contracts, local installation scripts, and testing suites for each open-source project.
atTrack
An open-source, local-first personal career workspace built with Next.js 16, Electron 43, and SQLite. Features persistent multi-session background AI streaming, local sqlite-vec semantic document search, automated job application tracking, and safety-gated database mutation approvals with 60-second timeouts.
Syncly
Syncly replaces Chrome new-tab page with a fast, keyboard-friendly bookmark manager: contextual workspaces, cross-folder collections, instant fuzzy search, omnibox quick-actions, and multi-tier backups — all operating directly over native Chrome bookmarks with zero external accounts and zero telemetry.
Why we build open source
We believe critical personal tools — especially career documents, financial records, and medical files — must operate with local-first ownership and zero telemetry.
Local-First Sovereignty
Your data lives on your disk in SQLite. No cloud databases holding your resumes, salary notes, or interview prep transcripts.
Propose-Then-Approve Safety
Autonomous AI agents cannot make destructive database deletions without an interactive 60-second approval modal and anti-replay tokens.
Zero Vendor Lock-In
Permissively licensed under MIT. Fork, audit, extend, or package the desktop runtime without proprietary restrictions.
