Your throwaway ClickHouse database

One click gets you a real ClickHouse database on a real server: SQL over HTTP, native protocol, MySQL and PostgreSQL wire protocols, a web UI, and an SSH endpoint that already knows your GitHub keys.

Create a new ClickHouse database

Sign-in with GitHub is required — it prevents abuse, gives an audit trail, and lets us reuse your public SSH keys for authentication. We ask for no permissions beyond your public profile.

What you get

  • a database named after your GitHub login
  • a user with an autogenerated password
  • login with your GitHub SSH keys over SSH
  • HTTP(S), native TCP, MySQL & PostgreSQL protocols
  • gRPC and Arrow Flight endpoints
  • web UI and web terminal

Limitations

  • up to 10 tables, 25 GB per table
  • 5 concurrent queries, 30 s per query
  • 32 GB memory per query; under memory pressure the largest query is killed
  • quotas on read/written/returned data per 5 minutes
  • all CPU and disk bandwidth when idle, fair share between users under load
  • deleted when empty for a week or under disk pressure
