What is Harbor?

Harbor 2.16 RC1 brings official arm64 builds, custom project roles and smarter proxy caching.

Harbor spent September and October on security patch candidates and rolling back defaults that broke webhooks and legacy signer pulls. The first 2.16.0 candidate is the first feature release in that window. It adds full amd64 and arm64 builds, custom project roles in the UI, proxy-cache repository filters and referrer API proxying, and member audit events.

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.

Harbor vs Hatchet: editorial side-by-side

5.0

Harbor 2.16 RC1 brings official arm64 builds, custom project roles and smarter proxy caching.

◆ Current state

Harbor spent September and October on security patch candidates and rolling back defaults that broke webhooks and legacy signer pulls. The first 2.16.0 candidate is the first feature release in that window. It adds full amd64 and arm64 builds, custom project roles in the UI, proxy-cache repository filters and referrer API proxying, and member audit events.

◆ Where it's heading

The 2.16 line shifts Harbor from patching toward enterprise registry features: finer RBAC, deeper audit trails, and a proxy cache that handles OCI referrers such as signatures and SBOMs. Multi-arch builds make Harbor a straightforward fit for arm64 clusters. Security fixes keep landing alongside, so the 2.14 and 2.15 patch lines will likely continue.

◆ Prediction

Expect further 2.16.0 release candidates before GA, plus more 2.14.x and 2.15.x patch tags. Whether custom roles get a matching API-level story is not yet clear from these notes.

6.3

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.
