About Open Saas
FreemiumIntermediateNo APIWeb · CLI
Open SaaS is a 100% free, open-source boilerplate for building modern SaaS applications, built with React, Node.js, and Prisma, and powered by the Wasp full-stack framework. It provides a complete starting point with authentication (email, Google, GitHub, Slack, Microsoft), payment integrations (Stripe, Polar.sh, Lemon Squeezy), email sending, background jobs, file uploads to AWS S3, an admin dashboard with analytics (Plausible or Google), and a built-in blog with Astro. Designed for developers who want to ship fast without reinventing the wheel, it also includes AI-ready tooling: tailored AGENTS.md, skills, and a Claude Code plugin to streamline development with AI assistants. The template is fully open source, allowing you to deploy anywhere with a single command (`wasp deploy`) and avoid vendor lock-in. It's ideal for founders, freelancers, and teams looking to quickly launch a SaaS MVP with a proven stack and modern user experience. The included interactive course helps developers learn SaaS best practices as they build. Compared to other starters, Open SaaS offers deeper integration with AI coding assistants like Claude, making it a standout for developers who heavily use AI tools. Its opinionated but flexible architecture, backed by the Wasp framework, also simplifies complex tasks like file uploads and cron jobs.
Behind the Verdict
Open SaaS stands out by being entirely free and open-source while including features many paid starter kits charge for, like multiple OAuth providers, three payment integrations, background jobs, file uploads, and an admin dashboard. The AI-readiness—custom AGENTS.md, skills, and a Claude Code plugin—is a genuine win for developers who rely on AI coding assistants. The interactive course bundled with the template helps you learn SaaS patterns as you build. However, the opinionated Wasp framework is a double-edged sword: it simplifies things like auth and cron jobs, but it may feel restrictive if you prefer full control over your framework stack. Deploying requires trusting Wasp's deploy command, though you can also host manually. The template currently lacks built-in mobile support, and the demo pricing tiers (Hobby $9.99/mo, Pro $19.99/mo, 10 Credits $9.99) are example placeholders—you'll need to set up your own billing. For developers comfortable with Wasp and React, this is one of the fastest paths to a production-ready SaaS MVP.

Where the pricing makes sense
The company stage and team size where Open Saas's pricing actually pencils out — and where peers do it cheaper.
Open SaaS is entirely free to use—you only pay for the third-party services you integrate. For solo founders and small teams, it is significantly cheaper than paid alternatives like ShipFast ($79+). Enterprise teams needing compliance and support should consider commercial starters with SLAs.
Setup time & first value
How long it actually takes to get something useful out of Open Saas — broken out by persona, not the marketing-page minute.
Solo founders: clone repo, run `wasp start`, and have a local SaaS with demo auth and payments in under 10 minutes. Full customization and deployment may take a few hours to a day depending on your requirements.

Migrating in
- →From no-code SaaS builder like Bubble: migrate by reimplementing logic with Open SaaS's full-stack TypeScript and Wasp—expect a few weeks for complex apps.
Migrating out
- ↗To Next.js/Node.js manually: copy business logic and database schema (Prisma) to a new framework; Wasp-generated files may need adaptation.
