Knock
Knock adds single-step test runs and retries for failed workflow runs.
A side-by-side editorial comparison of Currents and Userback — release velocity, themes, recent moves, and the top alternatives to consider.
Currents opens every project on a health verdict: trend, state, and what to fix first.
Currents is a Playwright test dashboard rebuilding itself around agent access. Since September it shipped agent-readable failure links, scoped personal access tokens, a hosted MCP server with OAuth, run attachments and a trace API built for agents. The Oct 19 Project Overview adds a human-facing counterpart: projects now open on a page saying whether the suite is healthy, which way it is trending, and what to fix first.
Userback launches Sites, but the release notes don't say yet what Sites does.
Userback has spent 2026 adding capture surfaces and AI on top of its feedback widget: MCP and a mobile SDK in April, Insights theme detection, video transcription in May, and mobile surveys in August. On October 5 it shipped 'Sites', which the team calls a big release, but the captured entry has no details beyond that line.

The Oct 19 Project Overview adds a human-facing counterpart: projects now open on a page saying whether the suite is healthy, which way it is trending, and what to fix first.
The product is converging on triage as its core job, for both audiences. Agents get granular paths into failures, traces and logs; humans get a prioritized summary instead of raw run lists. Both point at the same promise: Currents decides what to look at, not just stores results.
Likely next is linking Overview's fix-first items to the agent surfaces, so a prioritized problem can be handed straight to an MCP or trace-API session. The entries don't yet show that connection.
Userback has spent 2026 adding capture surfaces and AI on top of its feedback widget: MCP and a mobile SDK in April, Insights theme detection, video transcription in May, and mobile surveys in August. On October 5 it shipped 'Sites', which the team calls a big release, but the captured entry has no details beyond that line.
The pattern is wider collection (web, mobile, Slack, surveys) feeding an analysis layer (Insights, transcription, MCP access for AI tools). Sites comes after a two-month gap and is described as major, so it may extend this, but the entry doesn't show how.
It isn't clear from the entries what Sites is or how it fits with Insights and MCP. The next releases should show whether it is a new product surface or a reorganization of existing projects.
