# Open SaaS Alternatives — full catalogue

# Open SaaS Alternatives

> A directory of open-source and licence-free software a small business can run instead of paying a per-seat SaaS bill. Scores use public repository signals. Unknown figures are left blank. The site is not affiliated with the SaaS products it names.

Last updated: 15 Oct 2026. Repository figures were captured on 2026-10-15 (GitHub REST API + LICENSE files read 2026-10-15; releases from releases.atom; docker/ci from raw file HEAD; OpenSSF Scorecard where the project was in the dataset.).

## Key facts

- Site: https://opensaasalternatives.com/
- 15 categories, 81 apps, 31 named SaaS products used as the job to replace.
- Score weights: Alive 20, Trusted 20, Takeoverable 25, Easy to run 20, Feature fit 15. Unmeasured signals are omitted. They are not scored as zero and the remaining points are not scaled up to 100.
- An archived repository forces the Alive pillar to 0.
- SeatLess apps use the same formula. They have no public repository, so GitHub health points are omitted, and they are not pinned to the top.
- Most incumbent list prices are not stored. The 3-year calculator uses the price on the visitor’s invoice. SaaS bill = seats × monthly price × 36. Owned = setup + (hosting + upkeep) × 36. The large number is the difference.
- Docker is mentioned only when the repository contains a production Dockerfile or Compose file. Done-for-you setup by SeatLess is offered on every app and labelled as such.
