Simulated Redis: every round trip takes 400ms.
const name = yield* redis.set("{user:42}:name", "Ada");
const visits = yield* redis.incr("{user:42}:visits");
const plan = yield* redis.get("{user:42}:plan");
Redis and Emails are live
Composable tools for Effect.
The infrastructure your app depends on, as Effect services: Layers you can swap and typed errors you can match on.
01The kit
Pick the pieces you need.
Every package is its own install with its own Layers, so your app only carries what it uses.
Redis
Redis for Effect v4. A native client with typed commands and scoped connections.
- Typed commands and Schema-backed keys
- Pipelines, transactions, Pub/Sub
- Cluster and Sentinel routing
Emails
One Email API across 16 providers, with React templates and bounded batches.
- Capability checks before sending
- Errors that say whether it was sent
- Batches of up to 1,000 messages
Storagecoming soon
Object storage for Effect. Put, scoped get, head, delete and paginated listing.
- Conditional writes, like create-only
- Single-use reads tied to their scope
- Lazy, paginated listing
Docs coming soon
How Effect Kit fits your app.
It doesn't replace anything in your Effect application. It adds services, typed errors and Layers that slot into the program you already have.

Run the packages in your browser.
Real Effect programs against a simulated backend. Press play, change a control, break things.

Start here
Drop in one Layer and keep going.
Install a package, provide its Layer next to the ones you already have, and yield the service where you need it. Nothing else in the program moves.
