Works with stacks you already use
One SDK across common frontends and runtimes. Fork the repo when you want full control.
Featured on
Deploy in your account. Quotas live in D1. Console access can require a one-time ack; usage still runs through your Worker with your keys.
14 platforms
Slack, Discord, Telegram, WhatsApp, Teams, and 9 more on one unified adapter interface.
AI-native
Streaming markdown, tool calling, MCP client, and LLM middleware pipeline built in.
30+ SDK modules
Rooms, presence, typing, history, agents, webhooks, cards, and more, all on @fluxy-chat/sdk.
Durable agents
WorkflowAgent persists to D1, survives deploys, and resumes from the last step.
Realtime voice
Bidirectional voice-to-voice AI with provider-agnostic abstraction.
MIT self-host
Deploy the Worker + D1 in your Cloudflare account. Read every line of source.
Messaging basics, on the edge
Channels, presence, mentions, and webhooks without bolting on another realtime vendor. Tap or hover a row on desktop.
Threads, polls, and translation are up to your product layer. FluxyChat ships the realtime core: rooms, presence, typing, delivery, and AI agent events.
What ships in the box
Edge delivery, AI-native streaming, 14 platform adapters, and a console for day-two work. You own the UI; we handle rooms, delivery, agents, and ops hooks.
Most teams glue together chat, AI, support, and compliance from different vendors. That gets expensive and hard to audit. FluxyChat puts 14 platform adapters, streaming AI, MCP tools, and governance hooks on the edge you already run.
- 14 platform adapters (Slack, Discord, Telegram, WhatsApp, Teams, +9)
- AI-native streaming with tool calling & HITL approval
- MCP client for external tool servers
- LLM middleware pipeline (guardrails, caching, RAG, PII redaction)
- WorkflowAgent for durable agent execution
- Card builder with Slack Block Kit & Teams Adaptive Cards
- DevTools playground & OpenTelemetry tracing
- GDPR export, audit trails, and retention policies
Already set up? Open the console for rooms, agents, and billing.
Built-in architecture
14 platform adapters
Slack, Discord, Telegram, WhatsApp, Teams, Email, SMS, Webhook, Matrix, and 5 more on one unified interface
Streaming markdown
Table buffering, code fence tracking, inline marker healing for clean partial renders during AI streaming
MCP client + tool calling
Consume any MCP-compatible tool server. Auto-convert to LLM function-calling format with HITL approval gates
Card builder
Composable rich messaging with JSX or function API. Slack Block Kit and Teams Adaptive Card renderers built in
Middleware pipeline
Transform messages and AI responses before they land
Moderate, validate, enrich, and fan out from the edge. LLM middleware supports guardrails, caching, RAG injection, PII redaction, and logging via wrapGenerate / wrapStream / transformParams. Policy code stays on the data path, not in a sidecar you forget to deploy.
Developers
SDK, CLI, docs, and console in one repo
Auth, rooms, and retries sit behind hooks and route handlers. Scaffold a new project with create-fluxy-chat CLI. When you need keys, quotas, or billing, open the operator UI instead of wiring another admin surface.
Where teams start
Live verticals, voice, and the server event bus
Polls, breakouts, stage go-live, collab CRDT, fleet GPS, and hybrid check-in fan out as server_event frames on the room WebSocket. Voice AI, streaming AI, MCP tools, and durable agents sit on the same worker, with production readiness labels on every surface.

Why usage-based quotas?▾
Cost tracks messages, AI invokes, and webhook volume. Self-serve plans include fixed monthly quotas; heavy usage can be metered on Growth and above.
Do AI agent invokes count against my quota?▾
Yes. Each plan includes a monthly agent invoke limit. Streaming AI, tool calls, and MCP interactions count as invokes.
Are stream, collab, game, and IoT modules extra?▾
No separate SKU. Platform modules run on the same room and worker. Quotas apply to messages and agent invokes like chat.
Enterprise vs Business?▾
Business is high-limit self-serve with SSO add-on and audit export. Enterprise adds SCIM, SLA, DLP, security review, and dedicated support.
Self-host vs hosted?▾
Same worker and SDK. Hosted is fastest to start; self-host gives full control on your Cloudflare account with MIT source.

What does it actually cost on Cloudflare?
Real numbers, not vague "contact sales" ranges. The free tier is generous; the paid tier scales with usage; self-host is just your Cloudflare bill. No per-connection pricing surprises.
FluxyChat runs entirely on your Cloudflare account. You pay Cloudflare directly no per-seat or per-message markup from us on the self-host path.
| Plan | Monthly messages | D1 reads / day | Cost (USD) | Best for |
|---|---|---|---|---|
| Workers Free | ~3M / mo (100k req/day × 30) | 5M / day | $0 | Hobby · early beta · <1k MAU |
| Workers Paid ($5/mo) | ~300M+ / mo | 25M+ / day | $5 + usage | Growing SaaS · 1k–100k MAU |
| Self-host on your CF account | Unlimited* | Your plan limits | Your plan cost | Enterprise · cost-sensitive · compliance |
* D1 storage cap: 10 GB on the free plan, unlimited on paid. Message fanout uses Durable Object egress see Cloudflare's current pricing for live numbers. Run pnpm run check:pricing to verify your env assumptions match the published rates.
FAQs
Questions we hear when teams compare hosted chat APIs and edge deployments.
What is the chat API vs the SDK?▾
Your backend talks to the Worker over HTTP. The browser uses @fluxy-chat/sdk to join a room, send, and render. Same product, two surfaces.
Can I keep the frontend on Vercel?▾
Yes. Lots of teams leave Next on Vercel or Netlify and run chat on Workers + Durable Objects. You skip the platform WebSocket limits and a second Pusher-style bill.
Is this Intercom, Zendesk, or a live-chat widget?▾
No. Those are support desks. FluxyChat is the room layer for chat inside your app: SDK, webhooks, agent timeline. You build the UI. Guide: /guides/in-app-chat-vs-support-desk.
Is this a Pusher or Ably replacement?▾
For tenant-scoped in-app chat on the edge, usually yes: rooms, history, reconnect, operator tools. For generic pub/sub or SMS/WhatsApp, keep those products and use FluxyChat for the chat slice.
How is this different from a fully managed vendor?▾
You can run the Worker and D1 in your Cloudflare account, read the MIT source, and control upgrades. Hosted cloud is there when you do not want to wire infra on day one.
Can I add moderation and webhooks?▾
Yes. Middleware on the edge, signed webhooks, and console pages for the boring admin work.
What are Durable Objects for chat?▾
Cloudflare puts shared state in a Durable Object. Chat rooms are the textbook case. FluxyChat uses one Room object per room and D1 for history. Guide: /guides/durable-objects-for-chat-rooms.
Humans and AI agents in the same room?▾
tool_call and tool_result ride the same WebSocket as user messages, so you replay one timeline instead of guessing what the agent did. Streaming markdown with table buffering and code fence tracking renders cleanly during AI responses. Guide: /guides/agent-events-same-websocket-stream.
What platforms do the multi-platform adapters support?▾
14 platforms behind a unified interface: Slack, Discord, Telegram, WhatsApp, Microsoft Teams, Email, SMS, Webhook, Matrix, and more. Each adapter handles platform-specific formatting, and the card builder renders Slack Block Kit and Teams Adaptive Cards natively.
What is MCP and how does FluxyChat use it?▾
Model Context Protocol lets your agents consume external tool servers. FluxyChat acts as an MCP client and auto-converts tools to LLM function-calling format. Point your agent at any MCP-compatible server.
Can I add guardrails or RAG to AI responses?▾
Yes. The LLM middleware pipeline supports wrapGenerate, wrapStream, and transformParams hooks. Plug in guardrails, caching, RAG injection, PII redaction, or logging on the edge before responses reach users.
Does WorkflowAgent survive deploys?▾
Yes. WorkflowAgent persists state to D1 after each step. If the Worker restarts or you deploy a new version, the agent resumes from the last completed step.
I finished Cloudflare's chat tutorial. Now what?▾
That tutorial is the right start. FluxyChat adds JWT, D1 history, reconnect in the SDK, and a console. See /guides/after-cloudflare-chat-tutorial.
Why not stay on Pusher?▾
You might not need to. Edge pricing you can read, self-host on your account, no socket VPS fleet. Compare at /compare.
Where should I start?▾
Run the quickstart for a JWT and first room, or read /guides if you are still picking between DIY Workers chat and a packaged layer.
Does a public dashboard mean anyone can spend my quota?▾
No. Billable calls need your JWTs and API keys. Turn on DASHBOARD_ACCESS_MODE=ack (and optional CONSOLE_GATE_SECRET) so console routes need a one-time ack first.
Build AI-native chat on infrastructure you own.
Start on the free tier with 14 platform adapters, streaming AI, and MCP tools. Run a pilot on hosted cloud, or deploy the worker in your Cloudflare account when you are ready.
