We had 200 tickets labeled tech-debt that nobody touched for two years. Pylon opened 40 PRs in the first week. Half are already merged.
Autonomous PR agent
Your repository has a new teammate
Codepylon runs agents that read your entire codebase, open pull requests, and defend them in review, closing the tickets your team never gets to.
// no credit card required runs on GitHub and GitLab
How it works
From ticket to merged PR, no human in the loop
01
Read the whole repo
Pylon indexes your repository graph, not just the file you are in. It understands module boundaries, import chains, test coverage gaps.
02
Open a real pull request
Not a suggestion. A diff, a branch, a PR description that explains what changed and why. Ready for your team to review.
03
Defend it in review
When a reviewer comments, Pylon reads the thread, updates the code, and re-requests review. It does not give up.
Agent catalog
Four agents. One codebase problem at a time.
Legacy modernization
Pylon-Migrate
Takes a module still written in Python 2, Rails 4, or jQuery 2 and submits a PR to bring it current. One module, done right.
CVE remediation
Pylon-Patch
Reads your dependency tree, finds the vulnerable package, applies the patch, updates tests, opens the PR before the sprint ends.
Dead code elimination
Pylon-Refactor
Finds functions called nowhere, variables set but never read, duplicate logic across modules. Cleans it without breaking anything.
Coverage gap fill
Pylon-Test
Reads your existing test suite, finds the untested paths, writes tests that pass the first time. Not placeholder stubs.
Integrations
Works inside the tools your team already uses
GitHub
GitLab
Linear
Jira
Slack
From teams using Pylon
Engineering teams closing the backlog
The thing that surprised me is how it handles review comments. It reads the thread, not just the inline comment, and actually fixes the right thing.
We built a rule: every CVE in our dependency scanner gets a Pylon-Patch job created automatically. Zero manual triage.
