Stackline is an autonomous agent that watches your git repos, writes tests on open PRs, reviews code for bugs, and reports to Slack — 24/7. No waiting on code review. No skipped tests. Just shipped code.
One-click GitHub App install. Stackline gets read access to your repos and nothing else.
Every PR is automatically reviewed the moment it opens. Tests are drafted. Issues are flagged. Nothing falls through.
Structured review in your PR. You merge when satisfied. Stackline handles the rest — every PR, every time.
Every pull request gets a structured first-pass review within minutes of opening. Bugs, security issues, logic gaps — caught before a human reviewer ever sees it.
Stackline drafts test cases for every PR automatically. Not just stubs — meaningful coverage for edge cases and error paths. You review, approve, merge.
Stackline blocks merges until tests pass and critical issues are resolved. No more shipping broken code at 11pm because CI was green but coverage was not.
Daily digest. Weekly velocity. Individual PR summaries. Stackline keeps your team informed without you lifting a finger.
"The problem isn't that we don't know how to write good code. It's that we don't have time to write the tests, do the reviews, and catch the bugs before they hit production."
"Stackline is the team member who never sleeps, never skips the boring part, and always catches the thing you would have missed at 2am."
GitHub processed 43.2 million pull requests per month in 2025. Median PR size jumped 33%. Developers are drowning in review backlog.
Stackline exists to make autonomous code review accessible to every team — not just the enterprises that can afford it.
Connect one repo. Watch it work. Subscribe when you're ready to scale.
Code review shouldn't be a luxury. Stackline is built for the developer who ships alone.
