Grit vs the MERN stack
These aren't the same kind of thing. MERN — MongoDB, Express, React, Node — is a popular stack you assemble yourself, all in JavaScript. Grit is one generated, batteries-included framework: a Go backend, a generated admin, and typed clients from a single command. MERN is one of the friendliest ways to learn and ship full-stack JS; the question is whether you want to wire the pieces or have them generated.
The short version
Reach for MERN when you want to stay in one language, keep full control over every layer, and lean on a huge community and a document database. Reach for Grit when you'd rather skip the assembly — a typed backend, auth, roles, jobs, an admin, and multiple clients generated for you — and you're happy with a relational database and a second language for the backend.
DIY vs generated
With MERN, nothing is generated: you build CRUD, auth, validation, and an admin by hand, exactly how you like them. With Grit, grit generate resource emits the model, service, handler, Zod schema, TS types, React Query hooks, and an admin page at once — the wiring MERN leaves to you.
Side by side
| Grit | MERN (assembled) | |
|---|---|---|
| What it is | One generated framework | A stack you assemble yourself |
| Backend language | Go (Gin + GORM) | JavaScript / Node (Express) |
| Database | PostgreSQL (relational) | MongoDB (document / NoSQL) |
| CRUD + resources | Generated in one command | Hand-write each route + model |
| Typed API → client | Generated Go → TS + Zod | Manual, or add tRPC / codegen |
| Admin panel | Generated, Filament-like | Build it yourself |
| Auth + RBAC | Built in (roles + permissions) | Wire up JWT / Passport yourself |
| Background jobs / cron | Built in (asynq) | Add a queue (BullMQ, etc.) |
| Storage, email, cache | Built in (S3/R2, Resend, Redis) | Wire up each yourself |
| Mobile + desktop clients | Generated (Expo, Wails) | Assemble separately |
| One language end to end | No — Go + TypeScript | Yes — JavaScript everywhere |
Choose Grit when
- You'd rather generate CRUD, an admin, and clients than build them by hand.
- Your data is relational and Postgres fits it better than documents.
- You want types flowing end to end — Go → TS + Zod — with no drift.
- You want Go's performance and batteries (auth, jobs, storage) included.
Choose MERN when
- You want one language — JavaScript — across the entire stack.
- Your data is unstructured or document-shaped and a NoSQL DB fits.
- You want full control and no opinions imposed on your structure.
- You value the huge community and the gentlest learning ramp.
The honest trade-off
Grit is opinionated, adds a second language (Go), and rides a younger ecosystem than the JS stacks — MERN has years of tutorials, jobs, and Stack Overflow answers behind it, and keeping everything in JavaScript is genuinely simpler to learn and hire for. In exchange, Grit hands you a typed backend, an admin, and clients you didn't assemble. If you want to stay all-JS with a document database and control every layer, MERN is a great choice. If you'd rather skip the wiring and start from a generated, typed, batteries-included stack, that's Grit.
