Lovable-like — AI Site Builder

import { Mesa } from "@mesadev/sdk";

const mesa = new Mesa();
const repo = await mesa.repos.create({ name: "user-site" });

// AI generates and commits site code
await repo.commit({
  files: {
    "index.html": generatedHTML,
    "styles.css": generatedCSS,
    "app.js": generatedJS,
  },
  message: "feat: create landing page"
});

// Deploy and get live URL
const deploy = await repo.deploy();
console.log(deploy.url); // https://user-site.mesa.dev

WHY MESA

Postgres + S3

Build it yourself.

Good luck.

No Git semantics

You lose branching, merging, and diff. Recreating version control is a project unto itself.

Custom everything

Indexing, search, conflict resolution—months of engineering before you ship anything.

Performance is your problem

Optimizing queries, caching, scaling—all on you to figure out.

GitHub

Hit the rate limit.

Retry in 3600 seconds.

Rate limits block agents

5,000 requests/hour sounds like a lot until your agent hits it in minutes.

Not designed for AI

Built for humans clicking buttons, not agents making thousands of API calls.

Latency kills loops

200-500ms per request adds up fast in tight agent feedback loops.

Mesa

Built for agents.

Ship today.

Full Git semantics

Branch, merge, diff, blame—everything you expect, via API.

No rate limits

Make as many requests as you need. We scale with your agents.

Sub-50ms latency

P99 under 50ms. Your agent loops stay fast.

FEATURES

File Storage

Time Machine for your agent's filesystem. Backed by Git and S3, with complete version history—branch, diff, and merge with sub-50ms latency.

Sub-50ms API latency
Built-in indexing & code search
Bidirectional GitHub sync
Bring-your-own S3

const repo = await mesa.repos.create({ name: "my-app" });

// Commit files with full Git semantics
await repo.commit({
  files: { "app.py": code },
  message: "feat: add auth flow"
});

// Branch and merge
const branch = await repo.branches.create("experiment");
await branch.commit({ files, message: "try new approach" });
await repo.merge(branch);

// Time travel: restore any previous state
await repo.checkout({ commit: "abc123" });

Your Agent

fs.writeFile("src/app.py", code)

fs.readFile("config.json")

fs.mkdir("components")

WHY MESA

Built for AI

Traditional code infrastructure wasn't designed for AI. Mesa is built from the ground up for autonomous coding systems, with APIs and performance that match how agents work.

Enterprise Ready

Tenant isolation, fine-grained access controls, and bring-your-own infrastructure. Deploy with confidence knowing your code is secure.

Developer First

Clean APIs, comprehensive documentation, and SDKs in your language of choice. We obsess over DX so you can focus on building.
