Compare the best free, open-source SaaS boilerplates you can self-host in 2026. Auth, Stripe billing, and deployment included — no licensing fees.
Building a SaaS from scratch means months of work on authentication, billing, email, and deployment before writing a single line of product code. Open-source boilerplates solve this — they give you a production-ready foundation you can self-host, customize, and ship without licensing fees or vendor lock-in. We compared every major open-source SaaS starter across frameworks (Next.js, Django, Laravel, Rails) and ranked them by feature completeness, community activity, and developer experience.
