We Felt Your Pain
As founders ourselves, we wasted thousands of hours building the same authentication, payment, and database code over and over.We thought: there has to be a better way.
The Old Way
- Weeks of setup before shipping anything
- Integrating authentication from scratch
- Building payment systems (complicated!)
- Configuring databases and migrations
- Managing deployments and DevOps
- Dealing with security vulnerabilities
By the time you're ready to ship, your funding is running out and your idea has pivoted 3 times.
The Closr Way
- Everything configured and ready to go
- Authentication built-in (Clerk)
- Payments integrated (Square)
- Database schema included (Prisma + PG)
- Deploy to Vercel in 2 minutes
- Security best practices pre-configured
Ship your product on day one. Focus on what makes your idea unique.
