Repo context
A live semantic index of every symbol, test, and commit — 128k files held in mind at once.
~ / platform
the platformOne agent. Full access to your stack.
Context, execution, sandboxed tests, and tools — the runtime that turns a plain-language task into a merged pull request.
Code generation
Typed, idiomatic code that matches your conventions — not generic boilerplate.
Sandboxed runs
Ephemeral containers execute your exact build, lint, and test commands, then vanish.
Multi-step agents
Plans, branches, and self-corrects across dozens of files until the task is genuinely done.
Tool integrations
GitHub, Linear, Slack, Sentry, and your own CLI — 40+ tools it can call unattended.
Review & PRs
Every change ships as a clean, summarized pull request with diffs and green checks.
live session
Watch it plan, then act.
Give Cipher a ticket. It maps the work into discrete steps, shows you the plan, and only then starts editing — narrating every command as it runs.
- Plans are legible and editable before execution
- Every command streams to your terminal in real time
- Failures are read, diagnosed, and retried automatically

128k-file context
No chunking, no lost threads. Cipher holds entire services in working memory.
// context.index()>_
Sandboxed exec
Every run is isolated, network-scoped, and destroyed on completion.
// runtime.sandbox()●
Zero data training
Your code is never used to train models. Self-host on Enterprise.
// privacy.strict()↻
Self-correcting
Reads its own test output and iterates until the suite is green.
// agent.retry()↷
Tool calling
Give it your APIs and CLIs; it plans, calls, and completes multi-step work.
// tools.invoke()API
One clean API
Drive Cipher from CI, a webhook, or the CLI. SDKs for every stack.

scale
From first prototype to billions of runs.
