I’ve noticed a renewed interest in open source eCommerce platforms lately, especially with more businesses looking for full control over their tech stack, customization, and long-term cost savings. I'm currently evaluating whether to go with a commercial SaaS or commit to an open source eCommerce marketplace for a project targeting multi-vendor and international audiences.

A few questions I’d love insights on:

• What are the top open source eCommerce platforms in 2025 worth considering (Magento Open Source, Bagisto, Saleor, etc.)?

• How do these platforms stack up for headless commerce use cases and PWA readiness?

• Are community-supported plugins/extensions reliable enough for production-grade marketplaces?

• What kind of DevOps and security overhead should I anticipate with a self-hosted eCommerce stack?

Would appreciate your feedback, recent experiences, or even benchmarks you’ve run. Especially interested in hearing from those running high-traffic or B2B storefronts.

Thanks in advance!
