The Problem
Recording is easy — until you ship
Adding recording to your macOS app looks easy enough. But as soon as you go beyond a group of test users, the problems start. An endless list of edge cases caused by different and exotic end-user setups will come your way. And that's even before you've added features like recording input, or syncing multiple sources. Trust us, we've been there — and many with us.
- 💸 Costly — fixing edge cases takes months of engineering.
- 🤬 UX impact — in the meantime, your users suffer from bugs.
- 🐌 Slowdown — bug-fixing instead of shipping valuable features.

Frequently Asked Questions
I've got RecordKit running in my app: what's next?
Get in touch and we'll figure out a license that fits your situation. You'll be ready to go in days.
What does pricing look like?
RecordKit is priced around an annual commercial license. We have options that work for anyone from indie developers to large enterprises. Email us for an offer tailored for you.
Can't we just build this ourselves instead?
You certainly can! But there is significant cost in tackling all of the real-world edge cases that your customers will run into. We've already solved those.
(In fact most of our customers tried themselves before concluding they have better things to do with their time.)
Does RecordKit work offline?
Yes. Licensed builds make no network connections of any kind.
Can you help us with integration?
A license includes direct access to our founding team — they'll even code side-by-side with your team.
