Do the work
Suggestions are cheap. We build an agent that finishes the task and shows a clean diff for it.

aboutBuilding the autonomous engineer.
We’re a small team obsessed with one idea: software should be able to write, test, and ship itself — with a human on review, not the keyboard.
./story
From a hackday script to a runtime teams trust.
Cipher started in 2023 as a weekend experiment that refused to just autocomplete. It read the repo. It made a plan. It ran the tests and fixed what broke. That gap — between a model that guesses and an agent that follows through — became the whole company.
Today Cipher opens thousands of pull requests a day for teams from two-person startups to public companies, on one belief: the best tooling disappears into work that simply gets shipped.

Trust is the product
Sandboxing, privacy, and legible plans aren’t features. They’re the ground everything stands on.
