Tester programme
Break it before our customers do
Point Caterfli at something you actually run, then tell us where it got in your way. Accepted testers get Pro free for one month. Our top testers keep it for life.
What testers get
Pro, free for one month
Applied to your own workspace, with no card and nothing to cancel. When it ends the workspace drops back to the free plan — every agent, connection and conversation stays exactly where it is.
Top testers keep it for life
The people whose reports actually change the product get Pro permanently. No leaderboard and no quota — we pick by hand, because the most valuable report is usually the one that is hardest to score.
A person reads every application
We look at your GitHub profile, not your star count. You get an email either way — including when the answer is no, with the reason.
The deal
What we actually want from you
Not a bug bounty, and not a survey. We want somebody using this on real work for a few weeks, because the interesting failures only show up when the data is real and the stakes are ordinary.
- Connect one system you really use A database, an internal API, an MCP server — whatever your team already lives in. One is enough.
- Tell us where it got in the way Especially the moments you expected it to just work and it did not.
- Show us what it refused Anything an agent stopped for approval when it should not have, or waved through when it should not have. This is the feedback we cannot generate ourselves.
- Be honest about giving up If you stopped using it after four days, that is a more useful report than a polite one at the end of the month.
Apply
One form, one profile
Create a free account first
The reward is a plan applied to your workspace, so there has to be one for it to land in. The free plan takes a minute and needs no card — then come back here and apply.
FAQ
Before you apply
What do I get?
An accepted tester gets Pro free for one month, applied to their own workspace. No card, and nothing starts charging when it ends — the workspace drops back to the free plan and every agent, connection and conversation stays exactly where it is.
What does "top tester" mean?
The testers whose reports actually change the product. We decide by hand rather than by a leaderboard, and there is no quota. A top tester keeps Pro for life, on us.
Why do you want my GitHub profile?
It is the fastest honest signal we have. We are not scoring your stars — we are checking that there is a person behind the application, and getting a sense of what you build so we know which part of the product to point you at.
Do I need to be a developer?
No. Caterfli is operated in plain language, and the people who find the sharpest edges are usually the ones running operations rather than writing code. The GitHub profile is identity, not a qualification.
What are you asking me to do?
Connect one system you actually use and work with it for a few weeks. Tell us where it got in your way — especially anything an agent refused to do, or stopped for approval when it should not have. That is the feedback we cannot get any other way.
How long does a decision take?
A person reads every application. You will get an email either way, whether we can take you on or not.
Can I apply more than once?
No — one application per person, and per GitHub account. That is what stops one account collecting the reward under several email addresses, so it applies to everybody. If we turn you down and your situation changes, get in touch rather than reapplying.
