A messaging platform for marketing, support and sales teams, combining live chat, campaigns, bots and a help center.
Chaskiq puts the front line of customer service into software you run yourself: a web messenger on your site, agents answering it, campaigns going out and a help center sitting behind both. The project describes itself as source available rather than fully open, a distinction worth understanding before building on it.
A Rails backend serves a GraphQL API with OAuth authorization, consumed by a React frontend. PostgreSQL holds the records and Redis handles caching and transient data, so the operational shape is familiar to anyone who has run a Rails application before.
The platform reaches well past a chat widget.
- Web messenger: an embeddable chat with a rich text editor, animated GIFs, embedded video, syntax-highlighted code and video calls over WebRTC.
- Segments and routing: customers are filtered by custom attributes and conversations routed to the right agent.
- Automation: triggerable conversational bots, onboarding tours and mailing campaigns run without an agent present.
- Help center: a multilingual article system that lives on a custom domain or inside the messenger itself.
- Integrations: WhatsApp, Twitter DM, Slack, Calendly, Zoom, Pipedrive and webhooks connect it to the rest of your stack.
- Governance: configurable GDPR consent, audits on access and record changes, and a composable roles and permissions system.
Development guides exist for macOS, Ubuntu, Windows and Docker, needing Ruby 2.6 or newer, PostgreSQL 10 or newer and Redis 2.6 or newer. A commercial license lifts the AGPL and commons clause terms for proprietary use.
Open source chat support widget for React, giving developers headless components, real-time messaging and the backend infrastructure behind them.
Cossistant ships a support chat widget as React components you compose, rather than a script tag that injects someone else's interface into your page. The approach is code-first and API-driven, with headless hooks and primitives, real-time messaging, and the backend to run all of it, documented for developers and the AI tools they use.
Two packages carry the client side. The React SDK provides the headless hooks and primitives, and a companion package adds Next.js bindings and utilities. Behind them sits a Turborepo monorepo running on Bun, with Hono and tRPC for the API, Drizzle ORM for the database, Better Auth for sessions, WebSockets for live messages, and Docker running Postgres and Redis locally.
The split between widget and infrastructure shapes what you actually get.
- Headless components: styling and layout stay yours, because the SDK ships behavior rather than a fixed look.
- Real-time messaging: conversations travel over WebSockets instead of polling an endpoint.
- Full backend: the API, database and auth are part of the project, not a hosted dependency you rent.
- Next.js package: a separate module covers the framework-specific bindings and utilities.
- Documentation: a quickstart for adding it to an app and a contributors guide.
The project is licensed AGPL-3.0 for non-commercial use, and commercial deployments need a license from the maintainers. It is part of the Vercel open source program and runs a program of its own for other open source projects. It suits a team that wants support chat in their product without handing the conversation to a third party.
