What is Vitest?
Vitest 5 reaches RC after a beta line that reworked config, mocking defaults, and the browser runner.
Vitest has spent the last two and a half months in a v5.0.0 beta train, and 5.0.0-rc.1 is the first release candidate. Each beta carried its own block of breaking changes rather than deferring them: config lookup no longer walks ancestor directories, @vitest/runner was inlined and unpublished, webdriverio was dropped, mocks now clear before each test by default, and reporter output moved to a .vitest directory. The RC adds nested projects, a shared Vite server across inline projects, and a failure when an asynchronous assertion is never awaited.
What is WeWeb?
WeWeb opens its no-code builder to AI agents via MCP, deepens Supabase ties
WeWeb is steadily turning its visual web-app builder into an AI- and agent-friendly platform. Recent releases added MCP support so external AI tools can build directly in a project, plus AI-assisted workflow debugging, WeWeb AI planning and task tracking, and expanded AI element support. The last two releases are quieter - editor fixes, a refresh-token action, and load-time work - so the AI push is currently in a consolidation stretch.

Vitest
5.0DEVOPS
Vitest 5 reaches RC after a beta line that reworked config, mocking defaults, and the browser runner.
◆ Current state
Vitest has spent the last two and a half months in a v5.0.0 beta train, and 5.0.0-rc.1 is the first release candidate. Each beta carried its own block of breaking changes rather than deferring them: config lookup no longer walks ancestor directories, @vitest/runner was inlined and unpublished, webdriverio was dropped, mocks now clear before each test by default, and reporter output moved to a .vitest directory. The RC adds nested projects, a shared Vite server across inline projects, and a failure when an asynchronous assertion is never awaited.
◆ Where it's heading
The through-line across beta.4 to rc.1 is consolidation of the runner's architecture — one config resolution path, one Vite server, one project tree that can nest — paired with defaults that surface mistakes instead of tolerating them (strict toHaveTextContent, hoistable-scope errors, unawaited assertions failing). The browser mode is being narrowed to a single first-party stack rather than a plugin matrix. Performance work is now targeted at memory retention in vm pools and large --changed graphs, which reads as pre-GA cleanup rather than new capability.
◆ Prediction
With breaking changes still landing in rc.1, expect at least one more RC to settle the nested-projects and shared-server behaviour before a v5.0.0 final.
WeWeb
5.0DEVOPS
WeWeb opens its no-code builder to AI agents via MCP, deepens Supabase ties
◆ Current state
WeWeb is steadily turning its visual web-app builder into an AI- and agent-friendly platform. Recent releases added MCP support so external AI tools can build directly in a project, plus AI-assisted workflow debugging, WeWeb AI planning and task tracking, and expanded AI element support. The last two releases are quieter - editor fixes, a refresh-token action, and load-time work - so the AI push is currently in a consolidation stretch.
◆ Where it's heading
The direction is AI-assisted and agent-driven app building on top of a Supabase-centric backend. MCP support makes the builder addressable by whatever AI tool a developer prefers, while in-product WeWeb AI gains planning, testing, and troubleshooting. Between feature drops the cadence fills with editor and publishing cleanup, which suggests the team is stabilizing the surfaces the AI layer drives rather than widening it every release.
◆ Prediction
Expect WeWeb AI and MCP to gain deeper build-and-debug autonomy, with the Supabase integration continuing to expand as the default backend.
