Open Saas
Free, open-source React + Node.js + Prisma SaaS starter kit with AI-ready tooling, powered by Wasp.
Open SaaS is a standout free starter kit for developers who want to ship a SaaS MVP fast and who are comfortable with the Wasp framework. Its AI-ready tooling (AGENTS.md, Claude Code plugin) genuinely streamlines AI-assisted development, a differentiator over next-js-based templates like ShipFast or saasfly.io. The trade-off: you're betting on Wasp, and you must bring your own API keys. If you prefer Next.js or need a traditional server-rendered stack, look elsewhere.

Skip Open SaaS if you prefer a traditional server-rendered stack like Next.js or if you're uncomfortable building your app on top of the Wasp framework, or if you need out-of-the-box mobile app support.
You'll need to pay for third-party services like Stripe, AWS S3, and email providers, as the template only integrates with them—API keys and usage costs are yours to bear.
Open SaaS itself is free and open-source, so your only cost is your time and third-party services. Compared to paid starters like ShipFast ($249 one-time) or saasfly.io (free tier), you save the license fee but invest in learning Wasp. For solo founders and small teams, the free price plus AI-ready tooling is unbeatable value, but budget for API costs.
In short
Open Saas — Free, open-source React + Node.js + Prisma SaaS starter kit with AI-ready tooling, powered by Wasp. Best for Solo founders, Freelancers, Small teams building MVP. Plans from $9.99/mo.

About Open Saas
Open SaaS is a free, open-source SaaS starter kit built with React, Node.js, and Prisma, powered by the Wasp full-stack framework. It gives you a complete, production-ready foundation to launch a SaaS product quickly: pre-configured authentication (email, Google, GitHub, Slack, Microsoft), payment integrations (Stripe, Polar.sh, Lemon Squeezy), email sending with cron jobs, file uploads to AWS S3 via presigned URLs, an admin dashboard with analytics (Plausible or Google), a built-in Astro blog, and E2E testing with Playwright. The template is designed for the AI era: it includes custom AGENTS.md files, skills, and a Claude Code plugin to supercharge your AI-assisted development workflow. You own all the code, so there's no vendor lock-in—deploy anywhere with a single command (`wasp deploy`). The project also includes an interactive course that teaches you SaaS best practices as you build. It's ideal for solo founders, freelancers, and developers who want to ship an MVP in days rather than weeks.
Behind the Verdict
Open SaaS shines as a free, open-source base for React developers who want a production-ready SaaS skeleton without reinventing the wheel. The integration of Wasp's abstractions means you get full-stack type safety, auto-generated CRUD, and simplified data modeling—all of which cut down boilerplate significantly. The starter includes a surprising amount of out-of-the-box functionality: auth with multiple providers, payment processing via Stripe, Polar.sh, or Lemon Squeezy, an admin dashboard with charts, and a blog. The AI-ready additions (AGENTS.md, Claude Code plugin) are a genuine differentiator in a crowded market of starter kits, saving you hours in setting up your AI workflow. The built-in course is a nice bonus for learning. However, the primary dependency on Wasp is a double-edged sword. If you're not familiar with it, there's a learning curve, and you're coupling your project to a specific framework. While you own the code, the architecture is opinionated. Also, you must supply your own API keys for services like Stripe and AWS, and you handle the real-world configuration of payments and email yourself. The template is geared toward web apps—there's no mobile support out of the box. For solo founders and small teams, it's an excellent starting point for a web-based SaaS. If you need a Next.js stack or have enterprise-level requirements, other options might be more appropriate.

Use Cases
- Launch a subscription-based SaaS with Stripe or Polar.sh in minutes
- Build an AI-powered app that needs file uploads, file processing, and background jobs
- Create a membership site with social logins and email campaigns
- Prototype and validate a SaaS idea using the pre-built admin dashboard and analytics
- Learn full-stack development with TypeScript, React, and Prisma in a real-world codebase
- Accelerate development with AI assistants using provided AGENTS.md and Claude Code plugin
Limitations
- Open SaaS is built around the Wasp framework, so if you prefer plain Next.js or a more traditional architecture, this may not fit.
- You must supply your own API keys for external services like Stripe and AWS, and you are responsible for configuring real payments and email in production.
- The template is web-focused, with no mobile app support.
- The included pricing tiers (Hobby, Pro) are demo examples, not actual billing plans—you need to set up your own subscription logic.
- There's also a learning curve if you're new to Wasp.

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 itself is free and open-source, so your only cost is your time and third-party services. Compared to paid starters like ShipFast ($249 one-time) or saasfly.io (free tier), you save the license fee but invest in learning Wasp. For solo founders and small teams, the free price plus AI-ready tooling is unbeatable value, but budget for API costs.
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.
For a developer familiar with Wasp, you can get a demo running in minutes and deploy to a platform like Fly.io within an hour. If you're new to Wasp, expect a few hours to set up the environment and review the architecture. The included course helps accelerate the learning curve.
Switching to or from Open Saas
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From a plain React app: You can gradually adopt Wasp's features by integrating the starter's structure, but the template is designed as a full-stack base, so a rewrite may be simpler.
- →From a manual boilerplate: Copy over your custom logic and reuse the starter's auth, payments, and dashboard components.
- ↗To a custom React+Node stack: Since you own all code, you can port the components and logic, but you'll lose Wasp's abstractions and need to set up infrastructure manually.
- ↗To a Next.js stack: You'll need to adapt the routing and API patterns; consider using a Next.js starter like ShipFast instead if migration is likely.
