Hatchet vs LaunchDarkly: at a glance
What is Hatchet?
Hatchet takes durable tasks serverless, with handlers for Cloudflare Workers, Vercel and Node.
Hatchet's new @hatchet-dev/serverless 0.1.0 runs tasks on Cloudflare Workers, Vercel and Node. An in-engine operator delivers them by signed POST or by an invocation websocket that also carries durable sleeps, waits and child runs. Around it, the engine shipped three patches in a day: DAG replays no longer take an advisory lock, worker shutdown now waits for durable tasks, and status queries use partition pruning. The API now declares 429 with Retry-After on every authenticated call.
What is LaunchDarkly?
LaunchDarkly is moving experiment analysis into the customer's own warehouse.
April's work runs on two tracks. Warehouse-native experimentation reached both Redshift and Databricks within a day of each other, letting teams run experiments in LaunchDarkly while metrics compute inside their own warehouse, with automated health checks added for those connections. Separately, the React SDK shipped a ground-up v4 rewrite on the new JavaScript client, and flags gained the ability to restore a previous version from change history.

Hatchet

Hatchet takes durable tasks serverless, with handlers for Cloudflare Workers, Vercel and Node.
◆ Current state
Hatchet's new @hatchet-dev/serverless 0.1.0 runs tasks on Cloudflare Workers, Vercel and Node. An in-engine operator delivers them by signed POST or by an invocation websocket that also carries durable sleeps, waits and child runs. Around it, the engine shipped three patches in a day: DAG replays no longer take an advisory lock, worker shutdown now waits for durable tasks, and status queries use partition pruning. The API now declares 429 with Retry-After on every authenticated call.
◆ Where it's heading
Until now, running Hatchet meant running long-lived workers. The serverless package removes that requirement, so durable execution can run where JavaScript teams already deploy. The engine work points the same way: rate limits declared in the spec, safer worker acks, cheaper status queries. Patch cadence is still very high, often several engine tags a day, and much of it fixes durable-task edge cases.
◆ Prediction
Expect quick 0.1.x serverless releases as early users hit edge cases on each platform, and possibly matching Python handlers. More engine patches on durable-task shutdown and replay are likely.

LaunchDarkly is moving experiment analysis into the customer's own warehouse.
◆ Current state
April's work runs on two tracks. Warehouse-native experimentation reached both Redshift and Databricks within a day of each other, letting teams run experiments in LaunchDarkly while metrics compute inside their own warehouse, with automated health checks added for those connections. Separately, the React SDK shipped a ground-up v4 rewrite on the new JavaScript client, and flags gained the ability to restore a previous version from change history.
◆ Where it's heading
The experimentation story is the one that matters. Rather than pulling customer event data into LaunchDarkly to analyse it, LaunchDarkly is computing where the data already lives — which sidesteps the data-movement and governance objections that stall experimentation platforms in larger companies. Shipping Redshift and Databricks back to back, then immediately adding connection health checks, is the pattern of a capability being made operational rather than demonstrated.
◆ Prediction
Expect the remaining major warehouses to follow the same integration pattern, and more tooling around connection reliability as the warehouse becomes a dependency in the experiment path. The SDK rewrite suggests the other client SDKs will be consolidated onto the same JavaScript core.
