Pager just blew up — 5xx spike on checkout-svc, started ~5 min ago.

How it works

Three pieces. That's it.

You bring the Slack workspace and the Anthropic key. Relay does the boring middle.

STEP 01

Create your workspace

Acme Robotics

acme.slack.com

Connect Slack

OAuth · ~2 minutes

STEP 02

Paste your Anthropic key

Drop your sk-ant- key in Settings. Encrypted at rest with AES-256-GCM. Your spend, your control.

STEP 03

@relay it

Add up to 25 agents by slug. Mention @relay or /relay <slug> in any channel. Replies post back in the thread.

What you get

A thin relay, not another platform.

Bring your own Anthropic key

You pay Anthropic directly. We just route the messages. AES-256-GCM-enveloped at rest, decrypted just-in-time.

Slack-native auth

OAuth per workspace, every install is signed by Slack. No shared bot tokens, no secrets in env vars.

Slug-based agent routing

Address agents by name: @relay vanguard ... or /relay alfred ... Thread continuity keeps follow-ups with the same agent.

Up to 25 agents per workspace

Mix Sonnet, Opus, Haiku — your call. Each gets its own slug, system prompt, and environment.

Audit log built in

Every routed message lands as a row: who, when, which agent, which channel, which CMA session. Searchable.

Up to 25 users

Email invite flow, admin + member roles. When you outgrow it, the Enterprise upsell sits right next to the limit.

Commands

Slack is the terminal.

Four ways to invoke. Pick the one that fits your team's muscle memory.

The next thread isn't going to wait.

Sign up, install Relay in your Slack workspace, paste your Anthropic key, and the next time someone needs an answer in #help they'll have one before they finish typing the question.
