run402 - The full stack an AI agent can spin up and pay for

run402 is a full-stack platform (Postgres, auth, storage, functions, frontend hosting) an AI agent can provision, deploy, and pay for on its own: per call via x402 or MPP, or card credits as its allowance. Atomic deploys, hard spend caps, structured errors. Open source.

kysigned - E-sign documents by forwarding an email. $0.25.

No signature company to trust. Forward the document, type "I sign this document", and your email provider's DKIM signature, the one that already authenticates your mail, signs it. The proof is one self-contained file anyone can verify offline in a browser: no account, no app, it holds up even if we disappear. We never hold a key, so we can't forge or alter anything. Open source, Apache-2.0: self-host, or use the hosted version. Start with 4 free, then $0.25 a document, no subscription.
