Managed durable event bus · Realtime · Reliable delivery · AI-native

One line to wire events into your app and its agents.

Publish once and people and AI agents receive it in realtime; nothing is lost — every message is delivered at least once and stays replayable. Underneath is a managed durable event bus — no self-hosted Kafka, Redis, or polling logic.

What you can build

Four scenarios you can ship within a day

Each is the kind of thing that takes weeks to build yourself — and a few lines with MsgMesh.

{ }
01 / AI-NATIVE

AI agents subscribe to events and react

Paste a snippet of config into Claude Desktop / Cursor and your agent watches your streams all night: orders handled the moment they arrive, alerts reported the moment they fire — no polling or relaying in between. Underneath is MCP's watch_topic long-lived loop.

Why MsgMesh: native MCP access for agents — no event bridge to build for them.

02 / REALTIME

Realtime chat / multiplayer collaboration

Chat, co-editing, live interaction — messages arrive in realtime, and the header can even show how many people are online. Open unlimited isolated rooms within one stream via room, instead of a topic per group; browsers connect directly with short-lived tokens, so your backend never exposes long-lived keys.

Why MsgMesh: presence, reconnects, and auth are built in — skipping a whole WebSocket stack.

03 / WEBHOOK

App event notifications / webhook relay

Deliver notifications reliably from system A to B, none dropped: automatic retries, anything undeliverable set aside to resend, and every message signed so the receiver can verify it. Delivery status is visible and replayable (HMAC + DLQ).

Why MsgMesh: no retries / DLQ / signing to write yourself, and no queue to run.

04 / VIBE CODING

Let the agent provision itself

In your AI IDE, just tell the agent “create a key that can send and receive, and watch this topic” — it bootstraps itself with create_key / create_topic, and you never open the panel.

Why MsgMesh: onboarding compressed into a single sentence of natural language.

Plans & pricing

See exactly what it costs

Start free, then move to usage-based pricing as you scale — limits and prices fully public, no hidden fees.

🚧 Free during beta with all features open. The plans and limits below are a planned direction and may change before launch based on real usage and feedback.

Free plan: 100K messages/month, 20 requests/sec, 3 topics, 1-day retention — free forever, no payment needed. PAYG usage-based: 2,000 requests/sec, 30-day retention, managed functions included, pricing announced at launch (lower unit price at higher volume), no monthly fee, no lock-in.

The free plan needs no payment; paid is pure usage — no monthly fee, no lock-in, pay for what you use. Payment is currently settled in the cryptocurrency USDT (TRC20 / ERC20).

5-minute setup

Copy, paste, run

Just watched events stream live in the Demo? Wire the same thing into your own app — pick any of the three paths below. Snippets are pulled live from the platform, so they always match the current API.

No key yet? After signing up, issue one on the panel's Keys page and set it as the MQ_API_KEY environment variable; or take the MCP path and just have your agent create_key itself.
