The autonomous backendbuilt for coding agents

Real Postgres, APIs, auth, storage, and realtime, driven by your agent over MCP, with every change governed, verified, and reversible.

A 63-second narrated film of Backenly. On screen, an MCP key is created in Backenly and pasted into Claude Code, which builds the backend for UrbanCart, an online store, and publishes it. Orders arrive, and the console shows its Database, Auth, Storage, Realtime and Monitoring pages. At 3:12 AM a request slows down; Backenly adds a missing index on its own, while a foreign-key fix waits until a person approves it. The narration: Copy one command. Paste it into your coding agent, and it’s connected. Ask for the backend you need. It builds through Backenly, and every change is verified. Publish it. And it’s live. Then the first orders come in. Each one lands in your database. With Auth, every customer signs in. Product photos load from Storage. Realtime streams every order. And Monitoring sees every request. And when something breaks while you’re away, Backenly finds it, fixes what’s safe, and proves the fix worked. Anything risky waits for you. Fixed, verified, and reversible.

Works with the agent you already use, and any other MCP host

  • Claude Code
  • Cursor
  • Codex
  • Antigravity
  • Cline
  • GitHub Copilot
  • Zed

Every change tested and reversible

One day on production. Your agent ships a feature and asks for something risky, then at 3am, with nobody online, Backenly fixes a slow query on its own.

One project, one day and one night, drawn from the real flow. Names and times are illustrative.

14:02

Your agent ships a feature

Backenly turns the request into planned steps, applies them behind a restore point, then tests the live backend with real requests. Done means it works, not that it ran.

17:40

Anything risky waits for you

A change that would delete data stops and shows you exactly what it touches. Your agent can ask. Only you can approve, and every change can be undone.

03:12

Backenly fixes it while you sleep

Every minute, on every plan, Backenly checks the live backend. It snapshots first, fixes only what is safe, tests the fix, and never spends your AI credits doing it.

Every primitive, wired together from the first table

Not a kit of parts for you to assemble. One backend, where the database, the API, auth, storage, realtime and functions already know about each other.

Postgres, a schema of your own

Tables, relations, indexes, constraints and pgvector, in a PostgreSQL schema per project. Isolation is a Postgres grant, not a WHERE clause.

  • Standard PostgreSQL
  • pgvector
  • Direct connection strings
  • pg_dump exports

Auth

Sign-up, OAuth, magic links and verification emails for your users. Each project signs with its own secret.

REST APIs

PostgREST serves every table from the catalog: filters, ordering, pagination, embedded resources, OpenAPI.

Realtime

Inserts, updates and deletes as they land, plus presence and broadcast. Delivered over SSE, with no socket server to run.

Storage

Buckets, uploads, metadata and expiring signed URLs, on local disk or any S3-compatible provider.

Functions and triggers

Run code on insert, update, delete or signup, or on a cron schedule. Webhooks and rate limits included.

Also built in

Every feature

Row-level security by description

Say who can read and write what. Backenly writes and enforces the Postgres policies.

Branches for risky work

Clone the backend, let your agent experiment, review the diff, merge what works.

Teams and organizations

Invite teammates with roles. Every actor writes to the same change ledger.

One command, and your agent reads the real schema

The key is scoped to one project and revocable from the dashboard. It can request a destructive change, and it can never approve one.

  • MCP server

    Typed tools for schema, data, auth, storage and functions. Driving the backend this way is never metered as AI.

  • CLI

    Schema, generated types, CI diffs, logs and read-only SQL: the part of the workflow that belongs in a pipeline.

  • Agent skill

    A canonical skill at backenly.com/skill.md, so an agent learns the platform before it touches anything.

terminal
# Project id and key: dashboard, Connect, Agents
claude mcp add backenly -- \
  npx -y @backenly/mcp-server --project <project-id> --key <mcp-key>

# Then, in a new session:
# > add comments to posts. Only the author can delete theirs.

Hosts load MCP servers when a session starts, so the tools appear in the next one.

Questions before you trust us with production

Anything else, ask the person who built it.

One command installs the Backenly MCP server for Claude Code, Cursor, Codex, Cline, or any MCP host. The key is scoped and revocable from your project dashboard. There is also a CLI (npx @backenly/cli) for schema, generated types, CI diffs, logs, and read-only SQL, and a canonical agent skill at backenly.com/skill.md.
