Free Claude credits for solo builders go through Amazon

In late May, Anthropic rebuilt its Claude for Startups page around a self-serve form. Before that you needed a link from a partner VC. The FAQ now answers "Do I need VC funding to apply?" with a plain no, which is true and a little misleading. Joining gets you the community, Founder Days, launch news and hackathon invitations. Credits are a separate question, and the same page is explicit about it: your company needs equity funding from an institutional investor, must have been founded in the last four years, and cannot have received Anthropic startup credits before. The official program terms add that Anthropic weighs traction, funding, and Claude usage.

There is also no published amount. The tiers that circulate ($5,000 direct, $25,000 with a partner code, $100,000 at Anthropic's discretion) come from third-party guides and appear nowhere on Anthropic's own pages. The $25,000 most people repeat seems to belong to the Menlo Anthology Fund, which is a venture fund and takes equity. Apply to the startup program anyway. It takes two minutes and costs nothing. Just do not budget against it.

The second thing the headline numbers hide is routing. Anthropic's startup credits work on Anthropic's own API and nowhere else; the program page says they cannot be used on Bedrock, Vertex, or other third-party platforms. Google's startup credits cover Gemini and bill third-party models directly. Microsoft's cover OpenAI models on Azure, and Claude is not one of them.

AWS runs the other direction. Activate credits are redeemable on third-party foundation models in Amazon Bedrock, and Anthropic's models are among them. That makes a $1,000 AWS grant the largest pot of Claude-spendable money most solo builders can get without a pitch deck. It is the one fact this post exists to deliver, and it lives in a cloud provider's FAQ rather than on the model vendor's page.

With an LLC, a domain email and a live website, the list is real but modest.

AWS Activate Founders is $1,000, with up to $5,000 for select participants. It wants a company founded within ten years, a working website, and an AWS account on the Paid plan. New accounts start on a Free plan that cannot receive credits, which is the step that trips people up. AWS says it answers within seven to ten business days.

Claude hackathons are the only route that ignores incorporation and funding entirely. For the Opus 4.6 and 4.7 builds, run with Cerebral Valley, 500 selected participants each got $500 in API credits for the week, with a $100,000 pool in Claude credits split among the winners. The 4.6 round drew more than 13,000 applicants, so treat selection as a lottery you enter every time. Anthropic lists upcoming events at anthropic.com/events, and community meetups gather at luma.com/claudecommunity.

Two Anthropic doors stay open without a company, if the work is genuinely research: External Researcher Access grants $1,000 for AI-safety work, and AI for Science goes to $20,000 over six months for researchers attached to an institution.

Everything else in the self-serve pile pays for someone else's models: Microsoft's $5,000 for GPT on Azure, Google's $2,000 for Gemini, and Cloudflare's entry tier with $2,500 of Workers AI for open models. That is still worth having. Bulk extraction, summarization and classification do not need Claude, and they are where a vibe-coded app quietly spends most of its tokens. I compared what those models cost to serve in the napkin math post, and the site's own inference table lists the list prices of every model it routes to.

Almost every program assumes a company that looks like a company. Form the LLC, get email on your own domain, and put a real product page on a real site before you apply anywhere. NVIDIA Inception requires incorporation outright, and Google's FAQ says it may turn down personal blogs and agencies.

Then give Anthropic something to look at. Its credits land on the Console organization you submit, so apply from the org that already carries your real traffic, not a fresh one.

The quiet rule: a company that has received Anthropic startup credits cannot receive them again. If an accelerator or a small check is plausibly a few months away, joining now is free, but asking for credits now may spend your one chance on the smallest award.

If your monthly API spend is in the tens of dollars, forming a company to chase a $1,000 grant is paperwork dressed up as savings: a state filing fee, an annual report, a separate bank account, and credits that expire. Anthropic's credit terms default promotional credits to one year from issue unless the grant says otherwise. Run your own number below. With the company formed and a hackathon seat won, the $1,500 of Claude money outlives that year at anything under $125 a month, and the surplus simply lapses.

Credits are the loud lever. The quiet ones cost nothing to apply for. Some of the work never needs a hosted model at all: this site's semantic shelf runs its embeddings on the reader's own device, and the Hugging Face field notes track which open models are good enough to try first. I wrote up how that went in three trips into Hugging Face. The other quiet lever is noticing what runs while you are not looking. A scheduled job that fires every hour costs money whether or not anyone reads its output; did the cron actually fire is about catching the ones that do nothing, and the cheaper fix is often turning them off.

And if you are the reader this post is for, notice the pattern. Tracking down a dozen programs, building a table of their tiers and a toggle board of their gates is its own kind of vibe coding. I built the board anyway; it is above. The useful part fits on an index card.

Route bulk work to the free Gemini, Groq and Cloudflare tiers. Apply to AWS Activate Founders and spend it on Claude through Bedrock. Enter every Claude hackathon you can. Join Claude for Startups because it is free, and ask for credits only once real money is in the company. If that day comes, reapply everywhere at once, because an institutional check is the one lever that moves AWS, Microsoft, Google and Anthropic together.

Every figure here is as of September 26, 2026, and several of these programs changed between June and September alone. Independent trackers like Klymentiev's free LLM API list re-verify often, but check the vendor's own page before you plan around any of them.
