## Which one, for what

### MagicBell (C)

Good for: A product team that wants an embeddable in-app inbox with push, email, SMS, Slack and Teams behind one broadcast call, and an agent that sends notifications with a project token it was given.

Also in its favour:
- No incidents deducted, where Novu loses 13 points for them

Watch for: No batching or digest step found. Workflows have four commands (broadcast, wait, pause, abort)

### Novu (B)

Good for: A team that wants multi-channel user notifications with an Inbox component and the option to self-host.

Ahead on:
- Reliability, 93 against 75
- Schema & documentation, 92 against 68
- Agent ergonomics, 84 against 63
- Security & auth, 64 against 50
- Payments & pricing, 40 against 35
- Maintenance & community, 92 against 49
- Transparency & trust, 66 against 58

Also in its favour:
- Open source

Watch for: The REST secret key has full administrative access to its environment, with no scopes or read-only key

## Verdicts

**MagicBell.** A public OpenAPI 3.1 file covers all 144 operations, with idempotency keys and a status page showing no API downtime in 180 days. No batching or digest step, llms.txt, error code list, SLA or sub-processor list was found, and project tokens carry no scopes.

**Novu.** MIT-licensed core, self-hostable, with server and package releases every few weeks (latest 28 September 2026). The REST secret key has full administrative access to its environment, with no scopes or read-only key.

## Before you call either

### MagicBell

1. Ask the owner for a Project JWT from the dashboard's Project Auth page. The terms forbid accounts registered by automated methods
2. Send `Idempotency-Key` with a UUID on `POST /v2/broadcasts`, and reuse it on a retry within 24 hours
3. Stay under 500 requests a minute per IP. A 429 blocks the address for 60 seconds, so put many recipients in one broadcast
4. Use a Project JWT for broadcasts, users, integrations and workflows, and a User JWT for one user's inbox, tokens and preferences
5. Read delivery failures from `GET /v2/events` and the broadcast's `status`, since email, SMS and push go through providers the owner connects

### Novu

1. Send `Authorization: ApiKey <key>` to the REST API. Bearer is for the MCP server
2. Ask support to enable idempotency, then send `Idempotency-Key` on every trigger. A 409 means the first call is still running
3. Use eu.api.novu.co and eu.mcp.novu.co for an EU account. A US key won't authenticate there
4. Pass `environmentId` from `get_environments` on MCP calls. OAuth sessions default to Development
5. Keep `limit` at 100 or below on list calls. Higher values return 422
