Overview
Lints your code with a feather touch, flagging only the problems that matter. Includes the beloved rule "no-count-chickens-before-hatching" for async code.
FeatherLint is part of our Development Tools line, and it plays nicely with CluckCode and PecKit, so you can adopt it one perch at a time. Write, compile, and debug with the precision of a rooster's peck.
Teams usually start with the free Chick plan, move to Hen when the flock grows past a handful, and graduate to Rooster once the security team wants audit logs. The upgrade is one click, and nobody needs to molt.
Key features
- Works offline, because chickens do not trust the cloud near a fox.
- Hot-reload that is faster than a startled hen leaving a coop.
- Plugin system called Feed: anyone can drop in corn, and it gets pecked up.
- Ships with 40 keybindings, 39 of which are some variation of pecking Enter.
- Telemetry is opt-in, and the only thing we collect is the sound of you clucking in frustration.

What the flock says
It is, in the words of our CFO, "fine, actually good". We have it on tape.
Honestly better than the previous coop. Support answered within a cluck.
FeatherLint paid for itself the first week. Then it paid for the second week, too. Strange.
Frequently asked questions
Do you offer discounts for non-profits?
We offer 50% off to non-profits, schools, and sanctuaries. Rescue hens get a free Chick plan for life.
Where is my data stored?
In the coop you pick at sign-up. Data never leaves that region unless you tell it to. Chickens like to know where they live.
Can I try FeatherLint for free?
Yes. Every software product has a Chick plan that never expires, plus a 30-day trial of Hen, no credit card required. Just a firm, honest handshake with a wing.
