Ditch theSaaS Tax
Every alternative gets three independent scores — repo health, technical quality, dependency risk — not a vendor's pitch or a star count.
Three independent scores
Every app and package scored the same way — deterministic, disclosed, and repeatable.
Repo Health
Deterministic, pulled straight from GitHub — activity, maintenance, community, maturity, momentum. No opinions, just data.
Technical Score
A second, independent read — architecture, code quality, innovation, how hard it is to learn. Scored separately, so one bad metric can't hide behind the other.
Dependency Health
What the app depends on gets scored too — staleness, footprint, known vulnerabilities via OSV.dev. An app inherits every dependency's risk.
