LibFPGA Pro

Everything on LibFPGA stays free — the tools, the course, the playground, the library. Pro adds the conveniences working engineers asked for, and funds the free stuff for everyone else.

What Pro adds

  • API keys — generous rate limits for the JSON API: regenerate CRCs and register maps in CI without being polite about it.
  • Private, permanent snippets — share playground runs with your team, not the world.
  • VCD downloads — take any playground waveform into GTKWave.
  • Extended simulations — longer runs, bigger designs.
  • Ad-free, everywhere, forever.

$9/month

One plan. Cancel anytime. Expense it without a meeting.

Pro opens soon. Join the list and you'll get founding-member pricing when it does:

Prefer to support without subscribing? The library accepts GitHub Sponsors, and telling one colleague about the site helps more than you'd think.
