Cold starts steal the run
Every issue begins with dependency installs, missing tools and broken services. The agent spends its best context rebuilding what should already work.
Autonomous issue-to-PR delivery
Full speed.Verified landing.
Turn GitHub issues into merge-ready pull requests — lightning-fast, verified and secure.
FLIGHT LOG
Example issue
- Issue assigned — execution starts
- Environment ready — implementation starts
- Tests and declared checks — 86 / 86 passed
- Running app verification
- Merge-ready PR delivered
The problem
The agent is ready. The environment isn’t.
Verification gets cut first
When setup is slow or fragile, the budget for testing disappears. Code may arrive quickly, but confidence arrives late — or not at all.
Access expands the blast radius
Raw repository credentials and unrestricted network access turn hostile input into a path for credential theft and source-code exfiltration.
How it works
From issue to merge-ready PR
Codebase.run is work-item driven, not an interactive coding chat. Your setup ends at connecting the repository — the environment work is ours. GitHub issues are the task boundary, pull requests are the review boundary, and you keep merge authority.
-
Connect the repository
Install the GitHub App and pick a repository. That is the whole setup on your side.
-
We optimize the environment
Codebase.run prepares and validates a project-specific Agentic Work Environment — dependencies, toolchains and caches, ready before implementation begins.
-
Assign an issue
Assign a GitHub issue to Codebase.run. It takes it from there.
-
Watch it land
Review the merge-ready pull request and its execution evidence.
Why Codebase.run
Built for verified arrivals
Fast setup matters because verification that is too expensive gets skipped. Codebase.run treats the environment as a validated product artifact.
- fewer tokens spent on the same task
- ~2×
- faster execution, from issue to merge-ready PR
- ~4×
- testing and application checks become affordable
- deeper
Internal tests: identical tasks run in a prepared AWE versus a cold environment.
Warm start
We prepare dependencies, toolchains and caches ahead of time, so agent time is not spent on cold starts.
A running application
Codebase.run has the application environment ready before implementation begins — not just source files.
Credentials stay outside
Runtime credentials stay behind a proxy instead of entering the agent process, and outbound traffic is filtered against exfiltration.
Your model, your harness
The model and agent configuration remain project choices.
You own the merge
Every result arrives as a merge-ready pull request. You keep final control of the merge.
Who it is for
Bounded work, delivered for review
“Spend agent time on implementation and verification, not rebuilding the workstation.”
“Move a bounded software issue to a verified, merge-ready pull request without supervising an AI agent inside an IDE.”
