Free tier	250 MB data; 500,000 commands per month; 10 GB bandwidth per month; 10,000 commands per second; one database unit mixed; metered on request-count
Price	USD 0.20 per 100K commands; storage USD 0.25/GB-month beyond the first 1 GB

Identity	anonymous POST upstash.com/start-redis with an Idempotency-Key provisions a database with no account, no email and no card; the database is deleted after 3 days unless claimed in a browser. A permanent free database needs an email

Retention	a database on a free account persists while the account is active. An anonymous database created with no account is deleted after 3 days unless claimed (3 days)
Interface	rest, cli a body-style REST API that takes the command as a JSON array; the Redis protocol on the same endpoint; a developer API
Tooling	redis-cli against the TLS endpoint, or any HTTP client against the REST form; @upstash/redis SDKs
Composes with	the cheapest free cache in front of a free Postgres: 100,000 reads a day off the database, if the write path fits 1,000 a day
Reliability	an unclaimed database carries a warning not to store sensitive data because it is not tied to an account; the documented developer API host api.upstash.com did not resolve on 2026-10-22 while the per-database endpoint worked
Notes	The 10,000-commands-per-day figure in circulation is the pre-2025-03 plan. 500,000 a month is 16,600 a day, which is a different shape: a burst is fine and a steady 1/second is not.
Evidence note	measured a database was provisioned anonymously, PING/SET/GET/DBSIZE were run against it, and the 3-day expiry was read from the response. The free-plan limits are a first-party page.

Composes with	Free tier is 1 database per account (pricing table: 'Max databases \| 1'). 250 MB x N accounts. The command quota, not storage, is the wall: 500K commands/month = 16,667/day, and each GET returns at most 10 MB (verified), so max read throughput is 16,667 x 10 MB = 167 GB/day — 3x short of 500 GB/day even with a mythical 250 MB dataset read 667 times a day.
Reliability	Works and is fast; the killer is the command meter. Every GET, SET, EXISTS, and even pipelined command counts. Operational commands (PING, AUTH, INFO, CONFIG, SELECT, COMMAND, RESET, QUIT) are explicitly not charged. Free DBs minted anonymously are DELETED after 3 days unless claimed.
