Pro plan, forever free
The OSS grant
Full Pro. Free. For as long as you maintain.
This isn't a discounted plan or a 6-month trial. Approved OSS maintainers get the complete Dubleu Pro plan at no cost — unlimited projects, unlimited AI messages, Agent Mode, deploy, database, the works. It renews automatically every year as long as your project is still active.
Open source is infrastructure. We believe the people who build it deserve the best tools — not the budget tier.

Eligibility
Who qualifies?
We approve the vast majority of genuine OSS projects. Here's what we look for.
Active public repository
Your project must be publicly available on GitHub, GitLab, or another public host. Archived or private repos don't qualify.
Meaningful community use
We look for projects with real community traction — stars, forks, dependents, or active issue discussions. No minimum star count.
Open source licence
Your project must use an OSI-approved licence — MIT, Apache 2.0, GPL, MPL, and similar all qualify.
Non-commercial maintainer
The free Pro grant is for individual maintainers and small volunteer teams — not companies selling commercial products built on OSS wrappers.
