Fix handed over

The task goes to Lovable, Cursor, Claude Code or Codex. No code changes without your approval.

Task for your agent

Why not build it yourself

Sentry plus Codex, or Cirlo.

Your agent writes the code either way. The difference is what happens before and after.

What comes inSelf-built: Crashes that throw an error.Cirlo: Plus reports from your app, email, Slack and Discord, even when nothing crashes.
What comes firstSelf-built: Every crash on its own.Cirlo: Same reports grouped, sorted by affected users.
Who hears about itSelf-built: Only you.Cirlo: Every reporter, once the fix is live.

Context, not surveillance.

Cirlo sees what happened before a bug, without keystrokes and without continuous recording. The feedback button is smaller than a photo.

  • No replays
  • No videos
  • No keystrokes
  • No form values

The bug is done. So is the follow-up.

Every reporter hears about it personally, in their own language. Only once the fix is really live. And if the bug comes back, the issue reopens.

Everyone gets told

One fix. Every reporter informed.

Status without asking

A personal link shows where things stand.

Not fixed yet?

A reply reopens the issue.

An analyzed issue is the cause plus the finished task. Spam and reports that can't be reproduced don't count.

FAQ

The key questions. Answered briefly.

I build with Lovable, Bolt or Replit. Does that work?

Yes. You paste a text into your app's chat, and it has a feedback button. For every issue you get a finished task for the same chat, in Lovable with one click.

Once the bug is gone, you mark the issue as fixed and every reporter hears about it. You don't need Sentry or GitHub for that.

Does Cirlo fix bugs automatically?

Cirlo finds the cause and writes the task. Your own tool builds the fix: Lovable, Cursor, Claude Code or Codex. With GitHub, Cirlo files the task straight with your agent.

Cirlo notices when the fix is in and only then tells the reporters. For App Store apps the message says "coming with the next update".

Can't I just ask Codex or Claude Code?

Yes, for every bug you know about. Cirlo is for the others: reports sitting in your inbox, crashes nobody reported, and fixes that come back after the deploy.

And you can still hand every task to your own agent.

Who writes to my users?

You do. The message carries your name and replies come back to you. Unless you change it, nothing goes out before you approve it.

My users report bugs in Slack or Discord. Does that work?

Yes. You connect the one channel where people report. Every message there becomes a report, nobody has to learn a command or mention Cirlo.

And since Slack and Discord don't provide an email address, Cirlo replies in the same thread once the bug is fixed.

Do I need Sentry or GitHub?

No. The feedback button or support email are enough. With Sentry, Cirlo also finds crashes nobody reported. With GitHub, it notices by itself when the fix is in.

Does Cirlo change code without my approval?

No. No change goes in before you approve it.

What happens if Cirlo can't find a cause?

The issue says so openly and shows what was checked. You can pass it on or have it analyzed again later.

What do my users see?

The feedback button, their status link and messages about their own report. Diagnoses, code and other reporters stay hidden.

What happens to ideas, questions and praise?

Cirlo separates them from the bugs and collects them on their own page. If several people ask for the same thing, you'll see it.

Your app will have bugs. You don't have to give them your day.

Cirlo collects them, finds the cause and hands your agent the task.
