Hatchet vs Stacker
A side-by-side editorial comparison of Hatchet and Stacker — release velocity, themes, recent moves, and the top alternatives to consider.
Hatchet vs Stacker: 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 Stacker?
Stacker's AI agent has absorbed every part of app building except the data itself.
Stacker builds internal tools and customer portals on top of existing data. From late October 2025 the entire changelog is one project: an AI Builder Agent that generates and edits apps by conversation. In under seven weeks it went from generating initial pages and layouts to editing tables and fields, creating lookups, rollups and formulas, reshaping create forms, reordering navigation, building white-labelled external portals with custom domains and permissions, and finally taking a spreadsheet upload and configuring a schema and matching layouts from it.

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.
Stacker
0.0INFRA · APIS
Stacker's AI agent has absorbed every part of app building except the data itself.
◆ Current state
Stacker builds internal tools and customer portals on top of existing data. From late October 2025 the entire changelog is one project: an AI Builder Agent that generates and edits apps by conversation. In under seven weeks it went from generating initial pages and layouts to editing tables and fields, creating lookups, rollups and formulas, reshaping create forms, reordering navigation, building white-labelled external portals with custom domains and permissions, and finally taking a spreadsheet upload and configuring a schema and matching layouts from it.
◆ Where it's heading
The sequencing is deliberate: each release hands the agent one more thing that previously required the no-code editor, while the company repeatedly reassures users that the full editor still works on AI-built apps. That dual framing — build by conversation, refine by hand — is the position Stacker is defending, and it is a reasonable answer to pure prompt-to-app tools that leave nothing to adjust afterwards. The portal release is the notable widening, since it points the agent at the external-user product rather than internal tools.
◆ Prediction
Every surface except data connection has now been handed to the agent; connecting and mapping an external source — the step still done manually before any of this works — is the remaining gap, and the spreadsheet uploader is the first move toward closing it.
