Free Claude Max for Open-Source Maintainers

Free Claude Max for open-source maintainers: the short answer

Anthropic gives free Claude Max to open-source maintainers through a program called Claude for Open Source. An approved applicant gets six months of Claude Max 20x, the highest individual Max tier, at no cost. You qualify through one of several routes. Each route measures how much other code depends on your work. You apply with a form that uses GitHub sign-in.

Everything below comes from two pages we read on 2026-10-06: the program page at claude.com/open-source-max and the program terms at anthropic.com/claude-for-oss-terms. Both pages can change without notice. If a detail matters to you, read the live page before you rely on it.

What the program gives you

The program page states the offer in one line: "6 months of Claude Max on us." The terms name the plan precisely as "Claude Max 20x for a period of six months". That is the larger of the two Max tiers. Max is an individual plan, so the benefit is a complimentary subscription on your personal Claude account. Neither page mentions API credit.

This guide does not repeat what Max 20x includes, because those limits change and we track them in one place. For the difference between the two Max tiers, read Claude Max 5x vs 20x, the $100 and $200 plans compared. For what a single Max subscription covers across the Claude apps and Claude Code, read what one Claude Max plan covers. If you have never used Max before, how the Max usage limits reset explains the session and weekly windows you will work inside.

The terms also say the subscription cannot be sold or transferred, and that you are responsible for any tax on it. If you live somewhere a free subscription counts as income, check that before you accept.

Who qualifies: the five routes on the live page

The program page lists five groups. You need to meet one of them, not all of them. Here they are, quoted from the page as of 2026-10-06.

1. Maintainers and library authors: "500 or more dependent repos, 100 or more dependent packages, or 200,000 or more combined monthly downloads across any registry".
2. Core contributors: a "listed committer or maintainer on a recognized foundation or language project: CPython, Rust team, Node.js TSC, Apache PMC, CNCF, Kubernetes, Linux kernel, Django, Rails, or similar".
3. Active contributors: "100 or more pull requests merged into repos you don't own in the last 12 months".
4. Community builders: "20 or more unique external contributors with merged pull requests in the last 12 months".
5. Critical infrastructure: an "OpenSSF criticality score of 0.4 or above".

The last route uses the OpenSSF (Open Source Security Foundation) criticality score. That score runs from 0 to 1. It estimates how much the wider ecosystem depends on a project. A project at 0.4 or above is one that many other projects rely on.

The page also invites projects that the numbers miss: "If you maintain something the ecosystem quietly depends on, apply anyway and tell us about it." The terms call this the Ecosystem Impact Track. It covers people who "maintain or significantly contribute to a project that the open-source ecosystem meaningfully depends on", such as infrastructure libraries and developer tooling. This route has no number attached, so approval depends on how clearly you explain your project's role.

The eligibility rules changed after launch

If you read about this program elsewhere, you may have seen a different rule. Several third-party write-ups still describe a launch-era test based on GitHub stars and npm download counts, plus a fixed number of places. Those articles are out of date. The program page we read on 2026-10-06 does not use GitHub stars at all. It lists the five routes above instead.

The cap is less clear. The program page shows no cap. The terms page, read the same day, still says the program "is intended to provide subscriptions to up to 10,000 approved recipients", and Anthropic can raise that number. The page and the terms do not agree on this point. Treat the terms as the binding text, and do not assume places are unlimited. Anthropic does not publish how many places remain.

The practical lesson is simple. Trust the live page and the live terms. Do not trust any summary with no date on it, including this one a year from now.

The general requirements in the terms

In addition to one qualifying route, the terms set a short list of conditions that every applicant must meet:

• You are a natural person, not a company or other entity.
• You are at least 18, or the age of majority where you live, and you live where Claude is available.
• Your GitHub account is in good standing and at least two years old.
• You have public open-source contribution activity in the 90 days before you apply.
• You maintain or contribute to at least one project under an OSI-approved (Open Source Initiative) license.

The two-year account rule and the 90-day activity rule are the ones people miss. A maintainer who moved to a new GitHub account last year fails the age rule on that account, even with a long history on an older one. A maintainer who has been inactive for four months fails the activity rule until they contribute again.

How to apply, and are applications open?

You apply from the program page. The terms say applications go through a form at claude.com/open-source-max with GitHub sign-in. GitHub sign-in is how Anthropic checks your contribution history.

As of 2026-10-06 the program page shows an "Apply now" button. The terms say "the application period remains open until Anthropic closes it", and neither page gives a closing date. So applications were open on the day we checked, and no deadline is published.

The terms describe what happens after you apply:

• "Applications are reviewed on a rolling basis. Anthropic does not commit to any timeline for reviewing or responding to applications."
• "Anthropic will contact you only if your application is approved and does not send notifications for applications that are not approved."
• If approved, you get an email with a unique activation link, and you "must activate your subscription within 90 days".

The second point matters. Silence does not prove your application is still waiting for review. It can also mean a rejection, because rejected applicants get no message. Check the inbox tied to your Claude account. When the approval email arrives, write the 90-day activation deadline in your calendar, because an unused link expires.

What happens at month six

The free period ends on its own. The program page says: "At the end of the 6-month period, your complimentary subscription ends. We'll email you before it does." The terms add that it "does not renew automatically" unless Anthropic chooses to extend it.

If you were already paying for Claude when you were approved, your old plan restarts at your old price at the end of month six unless you cancel it. The program page puts it this way: "If you had a paid plan, it resumes at your prior plan and rate unless you cancel; otherwise your account returns to the free plan." The terms explain the mechanism. Your paid subscription is paused for the six months, not cancelled, and it "will resume at your then-current plan and rate".

This surprises people because six months is a long time to remember a paused plan. A maintainer who paid for Max 20x before approval will see that charge return in month seven. A maintainer who paid for Pro will drop from Max 20x back to Pro, and Pro billing restarts. The terms promise an email "at least 30 days before billing for a paused subscription resumes". Act on that email. If you do not want the old plan back, follow how to cancel or downgrade a Claude plan before the resume date.

If you had no paid plan, nothing is charged. Your account returns to the free plan.

Using the six months well

Six months on the top individual tier is enough time to learn what your real usage looks like. Track how close you get to the weekly limits in normal working weeks. That number tells you which paid plan, if any, you need when the free period ends. A maintainer who uses only a small part of the Max 20x allowance may find that Pro or Max 5x is enough afterwards.

If you plan to use Claude Code on your own project, check the project's contribution rules first. Many projects now have written rules for AI-assisted changes, and some refuse them completely. How open-source projects handle AI-assisted code covers the policies you are likely to meet as a contributor, and the ones you may want to write as a maintainer.

If you do not qualify: honest alternatives

Most developers do not meet any of the five routes, and no discount code changes that. These are the real options, as of October 2026.

• Students: many universities buy a campus-wide Claude for Education plan. Claude for students explains how to find out whether your school has one and what it includes.
• Nonprofits: Anthropic sells discounted Team and Enterprise plans to registered nonprofits. The nonprofit page lists Team at $8 per user per month, and $3 per user per month for organizations in low- and middle-income countries. This is for an organization, not for one person.
• Annual billing: Pro costs less per month when you pay for a year in advance. Max is billed monthly only, so this saving applies to Pro. Claude annual vs monthly billing shows when the yearly plan pays off.
• The right tier: much overspending comes from paying for more usage than you use. How to pay less for Claude covers the legitimate ways to cut the bill.

If you maintain something important that the numbers miss, the Ecosystem Impact route is the honest path. Apply, and describe plainly who depends on your project and how.

FAQ

Who qualifies for free Claude Max as an open-source maintainer?

As of 2026-10-06 you need to meet one of five routes on claude.com/open-source-max: 500+ dependent repos, 100+ dependent packages or 200,000+ combined monthly downloads; a listed committer or maintainer role on a recognized foundation or language project; 100+ merged pull requests to repos you do not own in 12 months; 20+ unique external contributors to your repo in 12 months; or an OpenSSF criticality score of 0.4 or above. You also need a GitHub account at least two years old, public activity in the last 90 days, and a project under an OSI-approved license.

Is the Claude for Open Source program still accepting applications?

On 2026-10-06 the program page showed an "Apply now" button, and the terms say the application period stays open until Anthropic closes it. No closing date is published. The terms still mention a limit of up to 10,000 approved recipients, which Anthropic can raise. The number of places left is not published.

Will I be charged when the six free months end?

Only if you had a paid Claude plan before you were approved. That plan is paused during the free period. It resumes at your previous plan and price at the end, unless you cancel it first. Anthropic says it emails you at least 30 days before billing resumes. If you had no paid plan, your account returns to the free plan and nothing is charged.

Why have I not heard back about my application?

Anthropic reviews applications on a rolling basis with no promised timeline, and the terms say it contacts only approved applicants. No reply can mean your application is still under review, or that it was not approved. If you are approved, you must use the activation link within 90 days.

Do I still need a minimum number of GitHub stars to qualify?

No. A star-count rule appears in older third-party articles about the program's launch. The live program page read on 2026-10-06 does not use GitHub stars. It uses dependents, downloads, merged pull requests, external contributors, foundation roles and the OpenSSF criticality score instead.
