Grit vs the MEAN stack
MEAN — MongoDB, Express, Angular, Node — is a popular full-stack JavaScript stack you assemble yourself, in one language, choosing and wiring each piece. Grit is one generated, typed, batteries-included stack: a Go backend, a React admin, and web/mobile/desktop clients from a single command. Same goal — ship a full-stack app — very different bet on how you get there.
The short version
Reach for MEAN when you want to stay all-JavaScript, lean on Angular's built-in structure for a large frontend team, and keep the freedom to assemble each layer — including a document database — exactly how you like. Reach for Grit when you'd rather have the backend, admin, auth, jobs, and typed clients generated and wired for you out of the box.
Assembly vs generation
MEAN is a set of parts you connect: Express routes, an Angular app, a Mongo schema, and every battery (auth, admin, jobs) added by hand. Grit is one opinionated stack where grit generate resource emits the model, service, handler, Zod schema, TS types, React Query hooks, and an admin page together — typed end to end.
Side by side
| Grit | MEAN (assembled) | |
|---|---|---|
| Backend language | Go (Gin + GORM) | JavaScript / TypeScript (Node + Express) |
| Frontend framework | React (Next.js or Vite/TanStack) | Angular (opinionated, TS) |
| Database | PostgreSQL (relational) | MongoDB (document / NoSQL) |
| Resource generation | model + service + handler + hooks + admin | Hand-written, nothing generated |
| Typed API → client | Generated Go → TS + Zod | Manual, or share TS interfaces |
| Admin panel | Generated, Filament-like | Build it yourself |
| Auth + RBAC | Built in (roles + permissions, 2FA) | Add libraries and wire it up |
| Background jobs / cron | Built in (asynq) | External queue / service |
| File storage, email, cache | Built in (S3/R2, Resend, Redis) | Wire up each yourself |
| Mobile + desktop clients | Generated (Expo, Wails) | Assemble separately |
| Database backups | Built in, scheduled + restore | Roll your own |
| One language everywhere | No (Go + TypeScript) | Yes (all JS/TS) |
Choose Grit when
- You want the backend, admin, auth, and jobs generated — not assembled by hand.
- A relational database (Postgres) fits your data better than documents.
- You want Go's performance and a single self-hosted binary.
- You prefer React, and want typed web, mobile, and desktop clients from one API.
Choose MEAN when
- You want to stay in one language — JavaScript/TypeScript top to bottom.
- A large team benefits from Angular's built-in structure (modules, DI, RxJS).
- Your data is a natural fit for a document (NoSQL) database like MongoDB.
- You value flexibility and a huge, mature JS community over an opinionated stack.
The honest trade-off
Grit asks you to work in two languages (Go and TypeScript) and lives in a younger ecosystem than the battle-tested JS stacks. In exchange you skip the assembly: the admin, auth, jobs, storage, and typed clients are generated and wired from day one. MEAN keeps everything in one language with maximum freedom, but that freedom is also the work — you build the admin, choose and connect each battery, and keep the pieces in sync yourself. If staying all-JS with Angular and a document DB matters most, MEAN is the honest pick; if you want a generated, typed Go backend with React and the batteries already in place, that's Grit.
