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.

What Makes Open Source Acquirable: Lessons from 149 YC Companies
Standalone apps get acquired roughly seven times more often than libraries. Stars barely matter. And the first three weeks after the deal predict the outcome better than anything in the press release.
