Looking for a free or open-source alternative to Coolors Pro? Paletteforge is the closest direct swap — MIT-licensed source on GitHub, or a $15 one-time packaged install. Since you're already auditing what you pay Coolors Pro every month, here are four more pay-once tools from the same catalog worth a look while you're at it — different jobs, same idea: buy the software once instead of renting it forever.
1. Paletteforge — replaces Coolors Pro
Palette generator with lock/shuffle, contrast checking, and CSS/Tailwind/ASE export — fully offline. $15 once vs Coolors Pro's $5.99/mo. Free on GitHub, or the packaged installer on Whop.

Why this list is worth bookmarking
Every app above is a one-time purchase with MIT-licensed source, no accounts with us and no telemetry. None of them are trying to be the next Coolors Pro — they're trying to be the last subscription you pay for that specific job.
