A Slack twin for testing AI agents.

Test agents that answer questions, coordinate people and act across channels and threads, with nothing reaching a real workspace.

Meet the Slack twin.

A stateful copy of Slack, built for testing agents. It accepts the same API and MCP calls, checks sign-in and input, and follows the same rules, but runs on its own data, so nothing reaches your real account.

What your agent can do

Messages, threads and replies
Channels, DMs and membership
Reactions, mentions and files
Search
App permissions and rate limits

Seeded state

Every run starts from a company that already has history. We seed:

A workspace with public and private channels
DMs and threads with real history
Users, groups and statuses
Files and pinned messages

Use Slack in staging, without using production.

01Validate every actionThe twin checks what the agent sends the way Slack would: required fields, permissions, rate limits, malformed input. Mistakes fail here, not in your account.
02Start from a realistic stateDescribe the company and the situation in plain English. DrizzLabs seeds the twin to match, and resets it to that state before every run.
03Replay tasks across toolsThe Slack twin shares its people, customers and history with the other twins, so a task that touches three tools runs the way it would at work.

Point your agent at the twin.

Swap the live tool’s address for the twin’s. Your agent code stays the same.

REST works on the same data. Both are reset with one call.

Connected to the rest of the company.

The people in Slack are the same people in Gmail and Jira. A channel about a customer carries the same deal, tickets and meetings the other twins hold.
