Hatchet
Hatchet takes durable tasks serverless, with handlers for Cloudflare Workers, Vercel and Node.
A side-by-side editorial comparison of Jackett and Optimizely — release velocity, themes, recent moves, and the top alternatives to consider.
Jackett ships a daily build to keep hundreds of torrent indexers working as sites move and close.
Jackett is an open-source proxy that turns hundreds of torrent tracker sites into a single Torznab API for media automation tools. It ships an auto-generated release roughly every day, and nearly every one is indexer upkeep: new domains, category mappings, selector fixes after site redesigns, and removing dead trackers.
Optimizely's public release feed is mostly roadmap scaffolding, with Opal AI as the visible bet.
The available updates are largely roadmap-page navigation and legal disclaimers rather than concrete release notes. The one substantive signal is the existence of a dedicated Opal AI roadmap surface, indicating the company is publicly anchoring its AI work under the Opal brand. Actual feature shipping cadence isn't visible through this channel.

The work is entirely maintenance. Its value depends on keeping up with a tracker ecosystem where sites change domains and layouts weekly. Where possible, the project is moving definitions to sturdier integrations, such as switching world-of-tomorrow to its Torznab API and retiring trackers that moved to direct downloads.
Expect the daily cadence to continue, with more trackers moved to API-based definitions and more dead sites removed. Core changes stay rare.

Optimizely appears to be repositioning publicly around Opal AI as the unifying narrative across content marketing, experimentation, personalization, and commerce. The dominant safe-harbor disclaimer language suggests the AI roadmap is still being marketed ahead of broad availability. Without concrete shipped features in the feed, it's hard to gauge real velocity.
Expect the Opal AI roadmap page to start filling in with shipped, branded capabilities (likely first in Personalization and Content Marketing where Optimizely has the most data leverage) rather than a single big launch.
