Diffbot and Remo follow the sponsorware release strategy, which means that new features are first exclusively released to sponsors as part of Insiders. Read on to learn what sponsorships achieve, how to become a sponsor to get access to Insiders, and what's in for you!

What is Insiders?

DiffBot and Remo Insiders are private forks of DiffBot and Remo respectively, hosted as a private GitHub repository. Almost1 all new features are developed as part of these forks, which means that they are immediately available to all eligible sponsors, as they are made collaborators of this repository.

Every feature is tied to a [funding goal] in monthly subscriptions. When a funding goal is hit, the features that are tied to it are merged back into DiffBot or Remo and released for general availability, making them available to all users. Bugfixes are always released in tandem.

Sponsorships start as low as $10 a month.2

What sponsorships achieve

Sponsorships make this project sustainable, as they buy the maintainers of this project time – a very scarce resource – which is spent on the development of new features, bug fixing, stability improvement, issue triage and general support. The biggest bottleneck in Open Source is time.3

How to become a sponsor

Thanks for your interest in sponsoring! In order to become an eligible sponsor with your GitHub account, visit fjp's sponsor profile, and complete a sponsorship of $10 a month or more. You can use your individual or organization GitHub account for sponsoring.

You can cancel your sponsorship anytime.4

Frequently asked questions


We don't want to pay for sponsorship every month. Are there any other options?

Yes. You can sponsor on a yearly basis by switching your GitHub account to a yearly billing cycle. If for some reason you cannot do that, you could also create a dedicated GitHub account with a yearly billing cycle, which you only use for sponsoring (some sponsors already do that).

If you have any problems or further questions, please reach out to


Are we allowed to use Insiders under the same terms and conditions as DiffBot and Remo?

Yes. Whether you're an individual or a company, you may use DiffBot and Remo Insiders precisely under the same terms as DiffBot and Remo, which are given by the BSD 3-Clause License. However, we kindly ask you to respect the following guidelines:

  • Please don't distribute the source code of Insiders. You may freely use it for public, private or commercial projects, privately fork or mirror it, but please don't make the source code public, as it would counteract the sponsorware strategy.

  • If you cancel your subscription, you're automatically removed as a collaborator and will miss out on all future updates of Insiders. However, you may use the latest version that's available to you as long as you like. Just remember that GitHub deletes private forks.

  1. In general, every new feature is first exclusively released to sponsors, but sometimes upstream dependencies enhance existing features that must be supported by DiffBot. 

  2. Note that $10 a month is the minimum amount to become eligible for Insiders. While GitHub Sponsors also allows to sponsor lower amounts or one-time amounts, those can't be granted access to Insiders due to technical reasons. 

  3. Making an Open Source project sustainable is exceptionally hard: maintainers burn out, projects are abandoned. That's not great and very unpredictable. The sponsorware model ensures that if you decide to use DiffBot or Remo, you can be sure that bugs are fixed quickly and new features are added regularly. 

  4. If you cancel your sponsorship, GitHub schedules a cancellation request which will become effective at the end of the billing cycle. This means that even though you cancel your sponsorship, you will keep your access to Insiders as long as your cancellation isn't effective. All charges are processed by GitHub through Stripe. As we don't receive any information regarding your payment, and GitHub doesn't offer refunds, sponsorships are non-refundable.
