What is Vitest?
Vitest 5 is in bug-fix mode: the second RC is almost entirely hardening
rc.2 carries one feature — a custom title for the GitHub Actions summary — and otherwise fixes the failure modes the RC period surfaced. The browser mode gets most of it: failing instead of hanging when the browser stops responding, exiting cleanly on disconnect during cancellation, and triggering Chromium GC when disk runs low. Snapshot evaluation moved server-side to work under a no-unsafe-eval CSP, and the UI now requires auth for coverage reports and every subtree request.
What is WeWeb?
WeWeb adds LLM calls to backend workflows, so the apps it builds can now ship AI of their own
WeWeb's visual builder is now working on two AI axes at once. MCP and WeWeb AI let external agents and the in-product assistant build the project, while the August 13 release lets the finished app call OpenAI, Anthropic, and Google Gemini models from backend workflows. The same release adds Make and Twilio integrations plus improved usage monitoring, and the month before it was mostly editor fixes, a refresh-token action, and load-time work.

Vitest 5 is in bug-fix mode: the second RC is almost entirely hardening
◆ Current state
rc.2 carries one feature — a custom title for the GitHub Actions summary — and otherwise fixes the failure modes the RC period surfaced. The browser mode gets most of it: failing instead of hanging when the browser stops responding, exiting cleanly on disconnect during cancellation, and triggering Chromium GC when disk runs low. Snapshot evaluation moved server-side to work under a no-unsafe-eval CSP, and the UI now requires auth for coverage reports and every subtree request.
◆ Where it's heading
The v5 line has spent four betas and two candidates reshaping config resolution, projects, mocking defaults, and the benchmark API; this candidate adds nothing to that surface and only stabilizes it. The concentration of browser-mode and pool fixes says that is where the remaining risk sits, and where real-world RC adoption is finding edges.
◆ Prediction
On this trajectory the next tag is either a final 5.0.0 or one more candidate, with browser mode the deciding factor rather than any remaining API work.

WeWeb adds LLM calls to backend workflows, so the apps it builds can now ship AI of their own
◆ Current state
WeWeb's visual builder is now working on two AI axes at once. MCP and WeWeb AI let external agents and the in-product assistant build the project, while the August 13 release lets the finished app call OpenAI, Anthropic, and Google Gemini models from backend workflows. The same release adds Make and Twilio integrations plus improved usage monitoring, and the month before it was mostly editor fixes, a refresh-token action, and load-time work.
◆ Where it's heading
The build-side AI story has matured into consolidation - planning, task tracking, and workflow debugging layered onto MCP rather than new agent surfaces. The newer direction is runtime: WeWeb is becoming a place to ship AI features, not only a place where AI helps assemble a page. Supabase remains the assumed backend, and the integration list is widening toward automation and messaging rather than more databases.
◆ Prediction
Expect the new backend AI actions to accumulate the plumbing a production AI feature needs - credential handling and cost controls tied to the usage monitoring shipped alongside them. The integration cadence points to more automation and messaging connectors before the next agent-side capability.
