Your AI agent never sleeps.

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.

You've never coded like this.

Clone a repo. Fix a bug. Ship it.

Not another app builder.

From intent to production in four steps.

01

Describe what you want

Tell Sifr what to build from your phone, laptop, or anywhere. "Add rate limiting to the /api/users endpoint."

02

AI implements it — in the cloud

Your agent reads your codebase, plans the approach, and writes the code in a persistent cloud workspace. Close the app — it keeps going.

03

Review on any device

Return hours later on any device. See exactly what changed — every file, every line. Diffs are clear and readable.

04

Approve and ship

One tap to approve. One tap to commit. One tap to push. Your code is live.
