Does opening the code make a product more production-ready — or less? We compared 205 open-source tools against 6639 closed web apps on the frames both can be measured on.

Open source vs Closed SaaS

What this compares

Four frames are measurable for both an open repo and a closed website — security posture, web standards, discoverability and maintenance. Each bar is the group average (0–100). Performance / accessibility / privacy need a rendered page, so they’re excluded to keep the comparison fair.

The takeaway

open source leads on security here. Open source gets credit for a license and an active history a crawler can verify; closed SaaS gets credit for the headers and polish a browser can see. Each is strong exactly where the other is opaque.

Sample composition

Not a random sample — this is what we measured. The mix below is the caveat; judge it for yourself.
