What is Convex?

Convex raised $57M on the argument that agents need a backend built for them.

The feed is thin on releases and heavy on company milestones. A $57M Series B led by Insight Partners is the newest item, pitched around developers and their agents writing software together and needing a backend that keeps up. The substantive product news remains April's Convex for Enterprise, which added the compliance and scale posture the platform previously lacked; since then the feed carries a conference announcement and open-source recaps rather than shipped capability.

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.

Convex raised $57M on the argument that agents need a backend built for them.

◆ Current state

The feed is thin on releases and heavy on company milestones. A $57M Series B led by Insight Partners is the newest item, pitched around developers and their agents writing software together and needing a backend that keeps up. The substantive product news remains April's Convex for Enterprise, which added the compliance and scale posture the platform previously lacked; since then the feed carries a conference announcement and open-source recaps rather than shipped capability.

◆ Where it's heading

Convex is funding and positioning ahead of shipping. The enterprise release established the upmarket motion and the funding narrative attaches it to agent-written code, but nothing in the visible window shows the agent-facing product surface that framing implies. Whether that framing is real or aspirational is not something this feed answers yet.

◆ Prediction

With the round announced around agent workloads, the next substantive release is most likely on that surface, though the entries here give no detail on what form it takes.

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.
