Show HN: Typebase – A single-folder back end you write in TypeScript (typebase.io)

Hey HN!

I built Typebase, a library that gives you Convex's DX with Supabase's openness.

After trying Supabase I liked how fast it is to spin up a DB and auth, but really didn't like using RLS and SQL for authorization. With Convex I loved how your server "lives" in your code, but disliked the DB model and the realtime-first defaults.

With Typebase you just write TS files inside a typebase/ folder in your existing repo. You can define your DB tables inside a schema.ts file and export server functions that your frontend calls like local functions, fully typed. Auth is built in.

Then one CLI command uploads your server to any of the available providers (Vercel, Cloudflare Workers or Deno Deploy for the servera and Neon for the DB), or generates the code so you can deploy it wherever you want.

Built on top of oRPC, Drizzle, and better-auth.

Happy to answer any questions or feedback!

It’s like next.js but for backend.

Personally not for me. These are very productive once you learn the shape they expect.

But the wheel needs to be reinvented on how to do everything.

I ran have straight forward verbose code with no hidden control flow


> once you learn the shape they expect

I’m reminded of this essay discussing frameworks versus libraries [0].

I’ve been saying for years we need CCR (Client Centric Rendering).

What we do is have the server just serve the page and let the client handle most of the rendering.

It’s novel and innovative


Smells like SPA

Am I missing something? The entire point of next.js is that it's backend+frontend in one project

that’s likely the promise but it’s so confusing and high cognitive overhead to maintain that backend <-> frontend relationship. ‘use client’ - i think the special sauce for why people use nextjs is all frontend based. the frontend that comes from the backend.

nextjs dx is a special kind of hell. disclaimer: im just a simple rails guy.


I love the (well-disclosed) fake testimonials. Hilarious!

> “I’ve told four separate therapists about Typebase. Two stopped taking me as a client. The other two are now shipping an app with it.”

So good. I laughed out loud at this.


Looks useful, congrats

I’ve been curious about trying the Supabase type of RLS model for an app but haven’t yet. I like the idea of the db defined api like postgraphile and hasura but had trouble with testing and ergonomics. This looks pretty nice though, it’s cool that you’re thinking about ergonomics for working with coding agents. I feel like a hard thing with that rn is that everyone is kind of figuring out different workflows for AI coding right now so it’s hard to optimize DX. Can you talk a little about your personal agent workflow and how this fits it?

I've only had experience in one full-stack project with supabase RLS so experience is limited. However it seemed like a mess. Seems much more human-maintainable to have a classic spring/golang backend. For sure in some projects, esp mobile apps, it makes more sense, and fable-level models might also keep it from being full spaghetti.

Also Supabase at that time wasn't reliable and it's not really made for self-hosting. Felt almost as bad as Github stability these days.

Still, based on this limited experience, I've been avoiding RLS and supabase.


I thought supabase was mainly for self hosting? Like it was self-hostable firebase... Not too familiar with it though.

Very cool!

Note that you can run Convex on top of your own Postgres, and we do this for our internal apps, with very nice performance (plenty for our internal use cases).


What, in your opinion, is this not a good fit for?

Enterprise software, stuff that you expect to scale exactly because it has queues and distributed computing.

very cool. though the deploy wasnt clear if i can just run migration on some pg url. and it wasnt clear if i can bind some middleware into my existing app server (like express)

I was about the ask a question but you just answered how it is built. I guess I will try it out, it sounds really good.

I love your approach, fake testemonials and all.


Fake reviews are a hard no-no imo. Really weird addition, but I suppose it wasn't you who got the idea.

Looks an awful lot like a orpc, just built on top of drizzle instead of raw queries. I'm sure some people want this, but it seems like gross duct tape that will bite you in three years


Scratching my head a little bit here, I'm not sure how this differs from NextJS (or Vite) with a layer of drizzle & better-auth.

Not that that layer isn't important. We ended up building something like this at Ingram, nextkit: https://github.com/ingram-technologies/nextkit - but we distribute it as a set of micro libraries that work well together rather than a unified framework. (Auth is nk-auth, built on top of betterauth, and sql is nk-db, built on top of drizzle)

You got to pretty much the same conclusions we did though regarding the "why".


This looks great. Question specifically on the Cloudflare Workers target: when you deploy there, does Typebase use D1 for the DB, or does the Postgres/Neon backend stay the same regardless of which server target you pick (Vercel/Workers/Deno) - i.e. is the DB layer decoupled from the server runtime, or does choosing Workers also mean choosing D1? I ask because I've shipped a small Workers+D1 service and the main friction I've hit isn't the server code, it's Workers' constraints around D1 (no long-running connections, HTTP-based driver quirks) - curious whether Typebase abstracts that away or whether you still feel it at the DB layer when targeting Workers specifically.

I see no code there to automatically pick D1 for the DB when you deploy to Cloudflare.

On Cloudflare, it should use the `@neondatabase/serverless` driver configured here https://github.com/typebase-io/monorepo/blob/fa3af0b71126caa...
