Typebase – A single-folder back end you write in TypeScript

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.

From the sources

Typebase is a type-safe backend you write as TypeScript files inside your existing repo. Define tables, server actions, and auth as plain TS. One CLI command ships them as a fully typed server. Built on oRPC, Drizzle, and better-auth.

Typebase adds a backend to your existing app. Write your database, server functions, and authentication in TypeScript. Deploy with one command.

// just use code. AI loves code. // just use code. AI loves code. Add a typebase/ folder to your repo: database, server functions, auth, and file storage, all in TypeScript. No dashboard settings, no SQL policies. Every rule is code your AI can see. Register this table in db/relations.ts to query it in your actions. Your database credentials and server logic stay on the server. The client guide covers creating and connecting your typed client. Define your Postgres tables in TypeScript. Typebase gives your server functions a typed database client. An action is a function that runs on your server. Typebase handles the endpoint and carries its types to your frontend.

In the maker’s words, at launch

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…

  Modelence – Supabase for MongoDB2025 · github.com · ▲38

  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 -…

  DBOS 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…

  Talanoa▲340

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  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…
