Puter.js user-pays developer offer: $0 infrastructure, no API keys high confidence
docs.puter.com and developer.puter.com (read 2026-10-22): developers pay $0 for infrastructure regardless of end-user count ('Whether your app has 1 user or 1 million users, it costs you zero to run'). End users cover their own AI/cloud consumption via their Puter account; 'each user gets pre-allocated resources' and every user 'starts with a free monthly allowance' (amount shown in usage dashboard, resets monthly, no rollover; purchased credits never expire). SDK exposes 500+ AI models (OpenAI, Claude, Gemini, Grok, etc.), cloud storage (puter.fs), serverless NoSQL KV (puter.kv), auth, serverless workers — via one script tag (https://js.puter.com/v2/), no API keys. Claims 80K+ developers, 130K+ apps, 400K+ installations. Matches the known baseline of in-browser IDE + instant live URL + user-pays model.
Eligibility
Any developer can use Puter.js free; no credit card, no company age/funding cap, no .edu requirement. Abuse is handled user-side ('abusers pay for themselves'), not via developer-side CAPTCHA or developer-side rate limits.
How to claim
Add <script src="https://js.puter.com/v2/"></script> (or npm @heyputer/puter.js) to your app; auth, storage, KV, AI and worker deployment work under the user's Puter account at $0 cost to you.
Expiry
No stated end date; free developer cost is architectural (user-pays), not a time-boxed trial.
Gotchas
Not a fixed credit grant: the free allowance amount is only visible per-user in the dashboard, not published. Free-tier caps apply to each end user's account (see quotas finding) — heavy users will hit limits or need paid plans themselves. Developer 'infra $0' claim excludes nothing else (e.g. no SLA stated).
Free-tier quotas & rate limits (Puter.js accounts) — exact published numbers high confidence
docs.puter.com/rate-limits-and-quotas/ (read 2026-10-22). Free (per user, per minute unless noted): AI 30 req/10s, 3 concurrent; KV get/set 400/10s, list 120/min, key 1 KB, value 400 KB; filesystem quota 100 MiB, write 120/min, stat 600/min; sites/workers: subdomain create 60/min, worker deploy 80/min, 5 concurrent workers; email 600 sends/min (but sendTransactional() paid-only); teams: 1 team/account, 3 free seats for owner; live connections 200/account; relay tokens 30/min; handler chain 4 runs. Free->paid deltas exist (e.g. AI 30->200 req/10s, concurrency 3->20, live connections 200->400). Usage credit: free monthly allowance resets monthly, no rollover; purchased credits never expire.
Eligibility
All free Puter.js accounts; same free allowance regardless of tier per docs.
How to claim
No claim step beyond creating a free Puter account; limits apply automatically and are documented at docs.puter.com/rate-limits-and-quotas/.
Expiry
Ongoing published schedule; credit portion resets monthly, no rollover.
Gotchas
Numbers are rate limits, not volumes — a 100 MiB free FS quota vs 25 MB on the marketing pricing page is a metering discrepancy (plan storage vs JS quota) that can confuse budgeting. Paid-only: transactional email, anyone-with-link shares. Event delivery has micro-cent costs (broadcast 10 μ¢/delivery, single 100 μ¢) and no-credit backlogs are deleted after 1 h.
Student/education license and startup program: none exist medium confidence
puter.com/education/ and puter.com/startups/ (fetched 2026-10-22) both fall back to the Puter homepage — no dedicated education or startup pages. docs.puter.com/llms.txt index (read 2026-10-22) contains no pages mentioning education, student, startup, trials or discounts. No .edu email path, no startup-credits application, no student discount on the $10/$25/$100 tiers.
Eligibility
N/A — no targeted offers to claim.
How to claim
Nothing to claim; students/startups get exactly the same $0 free plan + user-pays Puter.js as everyone else.
Expiry
N/A.
Gotchas
Web search budget was exhausted this session, so third-party/blog evidence of any announced 2025-2026 education or startup program (that would not yet be on official pages) could not be checked; conclusion is based on absence across all official pages fetched today.
