Backlit is in private, invite-only beta, public launch coming soon.
Coming soon

For AI agents

Agents deploy without asking

Backlit is built for two surfaces, and the agent surface is first-class. An AI agent can discover the platform, create a glow, push HTML, set an allowlist, and roll back, entirely on a user’s behalf, without a human touching a dashboard.

The MCP server and deploy API are open to private-beta accounts only right now. Public access is coming soon, the details below are for reference.

MCP server

Add Backlit as a custom connector once; your assistant gets a set of tools to build and deploy glows in the chat. No API keys to copy.

https://mcp.backlit.run/mcp

REST deploy API

A documented OpenAPI surface at a stable URL. Per-glow keys are scoped, revocable, and stored hash-only. Deploy and rollback are transactional.

backlit.run/openapi/glow.yaml

Deploy

# Upload a new version, a gzipped tar bundle of the site
curl -X POST https://glow.backlit.run/v1/glows/{id}/deploy \
  -H "Authorization: Bearer blk_..." \
  -F bundle=@site.tar.gz

# The live pointer flips in the same transaction, no partial state.
# Roll back instantly to any prior version:
curl -X POST https://glow.backlit.run/v1/glows/{id}/rollback \
  -H "Authorization: Bearer blk_..." \
  -d '{"version_id":"v-2026-05-24-abc"}'

Add Backlit to Claude

  1. Open Settings → Connectors (web: claude.ai/settings/connectors).
  2. Click Add custom connector.
  3. Name it Backlit and paste https://mcp.backlit.run/mcp.
  4. Click Connect and sign in to authorize.
  5. Add the deploy host https://glow.backlit.run under Settings → Capabilities → Domain allowlist, then enable the Backlit tools in a chat.
  6. Make your open chat aware of it. A conversation you already had running won’t notice the new connection on its own. Start a new chat, or tell Claude “Check your connections and use Backlit,” then ask it to publish.

Add Backlit to ChatGPT

  1. Open Settings → Connectors and enable Developer mode.
  2. Click Create (or Add custom connector).
  3. Name it Backlit and paste https://mcp.backlit.run/mcp.
  4. Set authentication to OAuth, click Connect, and sign in.
  5. Allow the deploy host https://glow.backlit.run, then turn on the Backlit connector in a chat.
  6. Make your open chat aware of it. An open conversation won’t load the new connector by itself. Start a new chat, or tell ChatGPT “Use the Backlit connector,” then ask it to publish.
