Yes. SpawnMail core is MIT licensed. You can run it on your own infra forever, with no limits on inboxes or emails. The cloud tiers pay for managed infrastructure, not the software itself.
Community is self-hosted — you run the Docker stack on your own servers. Cloud is managed by us — same codebase, but we handle uptime, scaling, DNS, and deliverability for you.
Absolutely. The API is identical. Point your agents at your self-hosted instance instead of api.spawnmail.sh and everything works the same.
API calls return 429 with a Retry-After header. No surprise charges, no silent degradation. Upgrade or wait for the next billing cycle.
