Anthropic’s Claude for OSS Program Adds Codenotary’s immudb

Codenotary says Anthropic’s Claude for OSS program will help accelerate immudb development and improve code quality.

In February, when Anthropic started handing out complimentary subscriptions to Claude Max 20x for a period of six months to qualifying open source developers and maintainers, a lot of people missed it.

That’s because the Claude for Open Source Program was given something of a stealth launch that was almost completely without ceremony. There seem to have been no embargoed press releases, or pesky PR agencies sending out interview offers to open source websites such as FOSS Force. Basically, the company just put up a webpage on its website as far as we can tell.

“Open-source contributors keep the ecosystem running,” the page reads. “The Claude for Open Source Program is our way of saying thank you for all your hard work, with six months of free Claude Max 20x. Apply now.”

The offer is pretty clean. Ahead of the ending of the six-month trial, Anthropic will send you an email. When D-Day arrives, if you were already a paying Anthropic customer, your prior plan and rate resumes unless you cancel or make some other adjustment. Everybody else gets returned to the free plan and its limitations.

Anthropic’s Program in a Nutshell

To be sure it’s a giveaway, but it’s also a marketing tool that’s something like an audition. It makes sense for most developers or maintainers to take part, because while you’re getting those tokens for free you can be checking out what works and doesn’t work when adding AI to your workflow. If you do it right, by the time the freebie runs out, you’ll already have the ineffective ways of using Claude weeded out of your workflow.

The program is something like Camel Filters used to be back in the days when cigarettes were advertised on TV. It’s not for anybody, and it’s not automatically available to anybody who wants to try it. The Anthropic post hints on who might qualify: maintainers who build packages that others build on, committers or maintainers working with a recognized foundation or language project, projects with repos that have had 20 or more unique external contributors with merged pull requests in the last 12 months, and more.

That being said, Anthropic is offering wiggle room for those who don’t automatically fit into one of its slots:

“Don’t quite fit? If you maintain something the ecosystem quietly depends on, apply anyway and tell us about it.”

How Codenotary’s Using the Program

When Codenotary announced last week that it’s been accepted into Anthropic’s program, it offered a good example of how six-months of free Claude use can be put to work. In this case, even though the company is heavily invested in deploying AI as part of its software supply chain trust arsenal, it’s going to use Claude to enhance development of immudb, its open source immutable database.

Immudb is an important part of Codenotary’s portfolio, as it provides its customers with a way to keep cryptographically verifiable records that can’t be altered. Organizations use it to strengthen software supply chain security, ensure regulatory compliance, protect digital evidence, secure financial systems, and establish trusted data foundations for AI applications.

“As immudb has matured into production infrastructure, engineering priorities have shifted from simply adding features to continuously improving quality, scalability, performance, backward compatibility, concurrency, and security,” the company said in a statement. “AI-assisted development provides new opportunities to help engineers tackle these increasingly complex challenges while maintaining the project’s uncompromising engineering standards.”

To be sure, Codenotary says it isn’t planning on turning development over to Claude. Rather than treating AI as an autonomous software developer, its stated plans are to integrate Claude as an engineering assistant that will help its developers increase their productivity across the software lifecycle.

“The future of software development isn’t human versus AI, trustworthy infrastructure software demands disciplined engineering,” Dennis Zimmer, Codenotary’s CTO and co-founder said. “It’s experienced engineers working alongside increasingly capable AI systems to build software that is more secure, more reliable, and delivered faster than ever before. That’s exactly how we intend to continue evolving immudb.

Free Claude Program’ Details

On the Claude for Open Source Program’s Terms and Conditions page, Anthropic says that going out the gate, the program was designed to provide subscriptions for up to 10,000 approved recipients. However, it’s keeping the door open, and says it might increase this cap.

There is a “one per person” rule in effect, and the company is hedging it’s bet on the program’s duration: “The application period remains open until Anthropic closes it,” it says.

Looking at how Codenotary is putting the program to use illustrates a positive side of AI, even for those who aren’t completely sold on the current AI push.

“Modern AI isn’t replacing open source developers — it’s making experienced engineers dramatically more effective,” said Zimmer. “Claude helps our team identify subtle bugs, reason across complex code paths, generate regression tests, review pull requests, and accelerate routine engineering work. Every line of code is still reviewed and approved by our engineers, but AI allows us to spend more time on architecture, security, and innovation.”

The company says that for security-critical infrastructure, AI can be used to enhance — but not replace — human expertise.
