Novu
Novu is the open-source notification infrastructure for developers. A single REST API and workflow engine route a triggered event across in-app inbox, email, SMS, push, chat (Slack / Discord / MS Teams / WhatsApp) and custom channels — with subscriber preferences, topics, digest, snooze, and full workflow orchestration on top. Ships with the embeddable React Inbox component, the Novu Framework for code-first workflow authoring, language SDKs for nine ecosystems, a Postman collection, an MCP server, GitHub Action sync, the Maily block-based email editor, framework starters for Next.js / Remix / Nuxt / SvelteKit, and webhook bridges for Stripe / Clerk / Segment.
Novu publishes 17 APIs on the APIs.io network, including Inbox / In-App API, Activity API, Channel Connections API, and 14 more. Tagged areas include Notifications, Messaging, In App, Email, and SMS.
The Novu catalog on APIs.io includes 1 event-driven AsyncAPI specification, 1 JSON-LD context, and 3 Spectral governance rulesets.
Novu’s developer surface includes authentication, developer portal, documentation, signup flow, pricing, engineering blog, GitHub presence, and 51 more developer resources.
