Platform
Everything you need to manage maintenance windows.
Stop shipping emergency deployments to flip a feature flag. maintenance.dev gives your team a single control plane for every maintenance scenario.
Real-time delivery
Persistent WebSocket connections push state changes to every connected user in milliseconds. No polling, no propagation delay.
Zero-deploy toggles
Flip maintenance on or off from the dashboard. Changes propagate instantly with no code deploys, CI/CD runs, or rollback windows.
Universal integration
One API for every platform. Drop a script tag on your website, hit our REST endpoint from your API, or subscribe via WebSocket from mobile.
Custom payloads
Define structured JSON payloads for mobile apps and APIs. Build your own UX while we handle distribution and state management.
Branded pages
Fully customizable maintenance pages with your colors, logo, and copy. Update messaging in real time during active maintenance.
Origin validation
Per-project allowed origins, project-scoped tokens, and connection limits. Production-ready security from day one.
Use cases
One platform, every surface.
Web, mobile, and backend teams use the same control plane. Different surfaces, identical guarantees.
Websites
Drop-in script integration
Add a single script tag to your site. We render the maintenance overlay on demand, with full control over styling and copy. Active users see the change without refreshing.

APIs
REST + WebSocket
Subscribe your services to project state via WebSocket, or fall back to a REST endpoint. Return the current maintenance status in any response your API serves.
GET /v1/projects/proj_a3f9c2{"in_maintenance": true,"message": "Scheduled maintenance"}
Mobile apps
Native payload delivery
Define a structured JSON payload your iOS or Android app understands. Receive it instantly via WebSocket and render any UX you want — full screen, banner, or modal.
{"in_maintenance": true,"screen": "FULL_SCREEN","title": "Back at 14:00 UTC"}
Page builder
Design maintenance pages without writing code.
Configure your branded maintenance experience with a visual editor. Pick colors, set messaging, upload your logo, and preview everything live.
- Custom background, modal, and text colors
- Branded image and logo upload
- Live preview before you publish
- Update copy mid-maintenance, no toggling required
