Typebase – A single-folder back end you write in TypeScript
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…
In plain words
Typebase is a TypeScript backend library that lets developers define databases, server functions, and authentication in a folder within their existing app repository. Frontend code calls backend functions like local functions with full type safety and zero REST boilerplate. It combines the developer experience of Convex with the openness of Supabase, built on oRPC, Drizzle, and better-auth. A single CLI command deploys to Vercel, Cloudflare Workers, Deno Deploy, or generates code for custom deployment.

Write actions, a database schema, and auth as TypeScript files in a typebase/ folder inside your app. Your frontend calls them like local functions, end-to-end typed, zero REST boilerplate.
// just use code. AI loves code. // just use code. AI loves code. Define your database schema, server actions, and auth in a typebase/ folder inside your app. One command deploys a fully typed server your frontend calls like local functions. import { action } from '../../_generated/server' ; import { z } from 'zod' ; export const getMany = action . output ( z . array ( z . object ( { id : z . number (), value : z . string (), }))) . handler ( async ( { db } ) => { return db . query . todos . findMany (); }); src/app/page.tsx client import { client } from '@/lib/typebase/client' ; export default async function Page () { const todos = await client . queries . todos . getMany (); // ^? {…from typebase.io
In the maker’s words, at launch
Hey HN! I built Typebase, a library that gives you Convex's DX with Supabase's openness.

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!

Hi all, Aram and Eduard here - authors of Modelence (https://github.com/modelence/modelence), an all-in-one backend platform for teams that love TypeScript + MongoDB. Think Supabase, but for MongoDB: auth, cron jobs, email, monitoring, without glue code before you can ship. As Karpathy (and many of us) noted, getting from prototype to production is mostly painful integration work. The pieces exist, but stitching them together reliably is the hard part: https://x.com/karpathy/status/1905051558783418370. YC AI Startup School talk about this -…
- DTDBOS TypeScript – Lightweight Durable Execution Built on Postgres2025 · github.com · ▲77
Hi HN - Peter from DBOS here with my co-founder Qian (qianl_cs) Today we want to share our TypeScript library for lightweight durable execution. We’ve been working on it since last year and recently released v2.0 with a ton of new features and major API overhaul. https://github.com/dbos-inc/dbos-transact-ts Durable execution means persisting the execution state of your program while it runs, so if it is ever interrupted or crashes, it automatically resumes from where it left off. Durable execution is useful for a lot of things: - Orchestrating long-running or…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
