Open source pricing tradeoffs
By Erik Loyd, SaaS CEO and former COO/CFO of an AWS Premier Partner.
Data as of October 16, 2026
"Open source" and "free" are not the same thing. Across the 1447 tools we have analyzed and classified by pricing model, 73.5% are genuinely, fully free with no paid tier waiting behind them. 23.9% offer free as a doorway to a paid plan: open core, freemium, or free to self-host but paid in the cloud.
The tradeoff sharpens with team size. Of the 1038 tools whose analysis covers large-team use, 801 are the right free choice for a solo developer. At least 247 of those same tools then point explicitly to a paid tier, an enterprise plan, or self-hosting once a large team depends on them. That gap is the clearest measure of what "free" stops covering as you scale. We count only the tools that say so outright, so the real number is higher.
How the catalog splits by pricing model
| Pricing model | Tools | Share |
|---|---|---|
| Fully free | 1063 | 73.5% |
| Open core | 181 | 12.5% |
| Free self-hosted, paid cloud | 145 | 10% |
| Source available | 38 | 2.6% |
| Freemium | 20 | 1.4% |
Where the recommendation flips by team size
Out of 1038 tools carrying a large-team recommendation. Recommendations are written as prose, so the third figure counts only tools that name a paid, enterprise, self-hosted, or licensed option outright — treat it as a floor, not a total.
Where open source most often means open core
Categories with at least 10 analyzed tools, ranked by the share shipped as open core: a free base with the features teams grow into held back for a paid edition.

Methodology
Every tool here has been read and classified by hand into one of five pricing models, and given a team-size recommendation for solo, small, and large teams. The classification rides alongside the same editorial pass that produces each tool's Lens and Discovery Score. For how the Discovery Score is built, see how we score tools. For who does the analysis and why, see about the author. The figures on this page are recomputed from the live catalog, not frozen into copy, so they move as the catalog grows.
