Open-source communication infrastructure that sends product notifications and connects agents to Inbox, email, SMS, push, chat and messaging channels.
Every product and every agent eventually has to talk to people on the channels those people already use. Novu is the open-source layer that handles that traffic, so teams stop rebuilding Inbox feeds, provider integrations and channel webhooks from scratch at the start of each project.
Two ways of building sit on the same foundation, one API and one unified conversation model. The first is notification infrastructure for products, delivering across Inbox, email, SMS, push and chat. The second is Agent Communication Infrastructure, which connects an agent you already built to Slack, Microsoft Teams, Telegram, WhatsApp and email.
The platform covers the parts most teams would otherwise write themselves.
- Workflow engine: notification workflows with branching and per-channel conditions decide how each message goes out.
- Digest engine: several notifications batch into one message instead of flooding a user.
- Embeddable Inbox: a real-time notification center component drops into a web app, alongside a preferences component users control themselves.
- Bidirectional messaging: inbound messages from each channel are normalized, routed to your agent and answered through the same layer.
- Bring your own agent: whatever you built works, and Novu places no constraint on the agent logic.
A no-code email editor and one API across messaging providers round out the product side. Novu connects an agent to the world rather than being the agent itself, and a single connect command wires an existing agent into Slack, Telegram or email in a couple of minutes for a trial.
A programmable telecommunications stack for developers who want voice applications and PBX features running on infrastructure they control themselves.
Telephony bolted onto an application usually arrives as a metered vendor API. Fonoster offers an open source alternative to Twilio, a programmable telecommunications stack connecting telephony services to the internet through a cloud-based utility, for businesses that want call handling on their own terms.
A Voice Application here is a server that controls the flow of a call, written with the Node.js SDK. Verbs such as answer, say, gather, dial, record and hangup compose the logic, speech is synthesized through Google Speech APIs, and a bidirectional stream carries audio both ways. Everything is API first, so originating a call is a handful of lines through the same SDK.
The platform covers the operational surface a phone system needs.
- Multitenancy: separate tenants served from a single deployment.
- PBX features: private branch exchange functionality deploys without manual assembly.
- Access control: OAuth2 and JWT authentication paired with role-based access control.
- Secure endpoints: API endpoints protected with Let's Encrypt certificates.
- Storage: recordings and media held through Amazon S3 support.
A plugin-based command-line tool handles administration, and self-hosting is documented as a Docker deployment. The project describes itself as researching this stack and still frames onboarding through an early access quickstart, so treat it as a platform under active development rather than a settled product. Development happens in the open, with issues and discussion on GitHub and a sizable Discord community around it.
