The short version

  • Only TimescaleDB has a free tier, so it costs nothing to try first.
  • Each has a real cost: Convex the Free and Starter tier includes only 1 million function calls and 0.5 GB of database storage per month before per-unit overage charges of $2.20 per million calls apply, as of August 2026.; TimescaleDB inherits PostgreSQL write path limitations, creating a ceiling on ingestion throughput
