Choose Medusa.js.
If you want to own your data, save money, and avoid vendor lock-in, Medusa.js is more popular among developers.
What Actually Matters
No fluff — just the differences that affect your decision
Both open source, different licenses: Medusa.js uses MIT, Posnic uses AGPL-3.0. Check the fine print if you're building commercial.
Medusa.js lets you self-host with Docker — your data, your rules. Posnic? Cloud only. If privacy matters, that's a dealbreaker.
Medusa.js dominates with 36.7k GitHub stars vs 11. Bigger community = more plugins, more answers on Stack Overflow, faster bug fixes.
Medusa.js is built in TypeScript, Posnic in JavaScript. Matters if you want to contribute, extend, or debug internals.
Try both — most offer free tiers. The right pick depends on your stack size, team, and tolerance for DevOps.
