Find real performance bottlenecks — and keep them fixed.

CodePerformance analyzes your GitHub PRs or branches to surface real performance issues — from inefficient algorithms to blocking I/O, database misuse, and scalability risks — and helps your team track, fix, and re-verify them iteratively.
It’s performance review as a shared workflow, not a one-time optimization pass.

Performance issues don’t fail at discovery. They fail at follow-through.

Most teams spot performance problems reactively:

A slow endpoint
A spike in infra costs
A late-night incident

Fixes get pushed, assumptions are made — and no one checks if things actually improved.

CodePerformance changes that

It turns performance optimization into a clear, trackable process, so:

Hot paths are identified early

Catch performance regressions before they ever touch production.

Ownership is clear

Assign issues to the right team members and track progress transparently.

Fixes are verified, not assumed

AI confirms if your changes actually solved the bottleneck.

Performance improves with every iteration

Turn optimization from a chore into a continuous improvement workflow.

Performance work shouldn’t be guesswork. Now it isn’t.

What CodePerformance gives you

1. AI-powered performance issue detection

Every selected PR or branch is reviewed for meaningful performance risks, including:

  • Algorithmic inefficiencies
  • Blocking I/O in hot paths
  • Database and external call misuse
  • Memory and allocation pressure
  • Concurrency and contention issues
Each issue includes severity (high / medium / low) based on expected impact.

2. Actionable, impact-driven fixes

Every issue comes with:

  • Clear explanation of why the code is slow or inefficient
  • File name & precise line numbers
  • Relevant code snippet
  • Concrete, implementation-ready fix
  • Expected performance improvement
No micro-optimizations. No vague “could be faster” notes.

3. A shared performance dashboard

All performance issues live in one place — visible to the entire team.

  • Assign issues
  • Track progress
  • Discuss and resolve collaboratively
CodePerformance feels less like a profiler and more like a project board for performance.

4. Iterative review & verification

Fixes don’t end the story.
When you push changes to GitHub and re-run a review:

  • AI verifies whether performance issues are actually resolved
  • Resolved issues are closed automatically
  • Unresolved ones stay open for further action
Optimize with confidence — not assumptions.

5. Full issue history & accountability

Every issue keeps its full history:

  • Assignee changes
  • Status updates
  • Review cycles

Your team always knows:

  • What was slow
  • What was fixed
  • What still needs attention
Performance becomes visible and measurable.

How CodePerformance works

Five simple steps to a faster application.

1. Connect GitHub

Link your GitHub account and choose a repository you want to optimize.

2. Select PR, branch, or files

Review an entire PR, a specific branch, or choose specific folders and files.

3. AI reviews your code for performance

Issues are identified across algorithms, I/O, databases, and memory — with clear severity and fixes.

4. Assign & fix collaboratively

Track issues using statuses: open → in progress → resolved → closed / rejected.

5. Re-review and verify

Push fixes, re-run CodePerformance, and let AI confirm what's truly improved.
