Graphbit PRFlow
Launched this week
Your AI teammate that reviews every pull request before it ships.
Tested on 10 real projects, PRFlow found 7 critical security issues where competitors found zero.
Learns your team's standards over time. Pay per review, not per seat.

Congrats! Does PRFlow reuse its cross file context across multiple PRs to speed up?
GraphBit
@owen_shaw2 Thanks, Owen. Yes, partially. PRFlow reuses repository memory and previously indexed context across PRs, so it avoids starting from zero each time. That helps reduce repeated context-building work, while the current PR still gets a fresh review.
GraphBit
@owen_shaw2 Fresh context per PR by design, stale context from previous merges would actually hurt accuracy more than help speed.
What persists across PRs is the memory layer: team corrections, false positive flags, and coding preferences. That's what improves over time, not the runtime.
Latency sits at 1 to 3 minutes regardless. Consistency has been the bigger win than speed for most teams 🙏
What’s one real issue PRFlow caught that you’ve never seen another tool flag?
GraphBit
@wyatt_carter XSS vulnerability that spanned three files- a Ruby controller, an HTML template, and a JavaScript file. The bug only existed in how they connected, not in any single file in isolation.
Every other tool we tested on the same PR found zero issues. PRFlow caught it because it traces the function that changed and follows its dependencies across the whole PR.
That one finding is what convinced us we were building something genuinely different
GraphBit
@wyatt_carter One was an XSS issue spread across a Ruby controller, an HTML template, and a JavaScript file. Nothing looked obviously broken in isolation, but the data flow across the three files created the vulnerability. PRFlow caught it because it traced the change across dependencies, while the other tools we tested on that PR found zero issues.
Does PRFlow support monorepos with cross-project dependencies out of the box?
GraphBit
@olivia_bennett7 Yes, for monorepos inside a single repo. PRFlow uses cross-file dependency analysis and repo-level context, so it can reason across multiple projects in the same PR, with practical limits on very large PRs.
GraphBit
@olivia_bennett7 Within a single repo it handles cross-file dependencies well out of the box. Full cross-project monorepo support is something we're working on.
What's your setup? Happy to tell you exactly what PRFlow would and wouldn't catch for your case
Can developers override or train PRFlow to learn their team’s specific patterns?
GraphBit
@daniel_harris11 Yes. When your team replies to a PRFlow comment, "this is intentional" or "we prefer this pattern" it stores that and applies it to future reviews automatically.
No manual training setup. It learns from how your team actually works
GraphBit
@daniel_harris11 Yes. Today that happens mainly through configuration plus feedback loops: repo-level review rules, ignored paths, path-specific focus, and explicit corrections from developers in PR conversations. That is how PRFlow starts aligning with team-specific patterns over time.
Can teams self host PRFlow, or is it entirely GitHub cloud based?
GraphBit
@asher_luca Thanks. Right now, PRFlow is GraphBit cloud-based rather than self-hosted. The review orchestration runs through the GraphBit cloud.
GraphBit
@asher_luca Cloud-based for now. Self-hosting is something we hear interest in, especially from enterprise teams. Good to know it matters to you, noting it
Does PRFlow post comments as a bot or as a check summary on GitHub?
GraphBit
@peyton_perez Thanks. It posts as a bot on the PR, with a review summary and inline comments when needed. Not just as a check summary.
GraphBit
@peyton_perez Exactly, inline comments directly on the PR, not just a check summary. So your team can reply, discuss, and resolve right in the thread where the code lives
Can I run PRFlow retroactively on closed PRs to audit past missed issues?
GraphBit
@gaius_loxley Not yet, PRFlow currently triggers on PR events, so it works on open and updated PRs. Retroactive auditing on closed PRs is something we've heard interest in. Good signal, noting it
GraphBit
@gaius_loxley Not yet. Right now PRFlow is event-driven, so it works on open and updated PRs rather than closed PRs retroactively.
