# LastSaaS

A free, MIT-licensed Go + React SaaS boilerplate with multi-tenant billing, RBAC, and an MCP server

https://topboilerplates.com/lastsaas

Framework: Go | Pricing: Free | GitHub stars: 160

## Verdict

Best for: Developers who want a Go backend instead of Node/Python for their SaaS, with multi-tenant billing, RBAC, and MFA already built in.

Skip if: You're not comfortable with Go, or you want a Postgres/SQL-based backend rather than MongoDB.

## Description

LastSaaS is an open-source, MIT-licensed SaaS boilerplate combining a Go backend (gorilla/mux) with a React 19 + TypeScript + Vite + Tailwind CSS frontend, built by Jon Radoff. It ships JWT/OAuth/MFA authentication, role-based access control, Stripe billing with subscriptions and credit-based usage, white-label branding, outgoing webhooks, system health monitoring, and an admin dashboard, plus an MCP server that lets AI assistants query admin data conversationally.

## Pros and cons

+ Free, open source, and MIT licensed with a real GitHub following (160 stars)

+ Go backend is a rare, welcome option among mostly Node/Python SaaS boilerplates

+ Includes credit-based usage metering and an MCP server for AI-assisted admin queries, both unusual extras

- MongoDB rather than Postgres may not fit teams standardized on relational databases

- Go + React combination requires comfort in two different language ecosystems

- Relatively young project (single maintainer, no changelog/roadmap visible) despite active recent commits
