AI agents run in the cloud — writing code, running tests, creating PRs —
while you're in a meeting, on a train, or asleep.
Your real GitHub repos. Your real codebase. From any device.
Clone a repo. Fix a bug. Ship it.
Sifr works on your existing codebases. Connect your GitHub, work on real repos, ship real changes.
Close your phone. Switch to your laptop. AI keeps coding in the cloud.
Start on mobile. Review on web. Ship from desktop. Same session, same branch, always synced.
Safe, Balanced, or Autonomous. Every AI action requires your permission level.
Commit, push, create PRs with co-authored commits. Real git on your actual codebase.
Encrypted CLI credentials for Expo, AWS, Vercel. Deploy to production from any device.
Claude 4.5, GPT-5.3 Codex, Gemini 3, and more. Pick or let Sifr auto-route.
Tell Sifr what to build from your phone, laptop, or anywhere. "Add rate limiting to the /api/users endpoint."
Your agent reads your codebase, plans the approach, and writes the code in a persistent cloud workspace. Close the app — it keeps going.
Return hours later on any device. See exactly what changed — every file, every line. Diffs are clear and readable.
One tap to approve. One tap to commit. One tap to push. Your code is live.
Join the waitlist for early access.
