Convex vs SurveyJS
A side-by-side editorial comparison of Convex and SurveyJS — release velocity, themes, recent moves, and the top alternatives to consider.
Convex vs SurveyJS: at a glance
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 SurveyJS?
SurveyJS keeps a notes-free v1 line alive while v3 grinds through theming in beta.
SurveyJS is maintaining two branches in parallel. The v1.12.x line ships tagged releases with no published notes — the feed carries only the version string and a CI skip marker — while v3.0.0 moves through numbered betas whose changelogs are raw PR lists dominated by theming, layout, and CSS variable work. Nothing in the recent window adds a question type or changes the library's public surface.
Convex vs SurveyJS: editorial side-by-side
Convex
2.5DEVOPS
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.
SurveyJS
5.0DEVOPS
SurveyJS keeps a notes-free v1 line alive while v3 grinds through theming in beta.
◆ Current state
SurveyJS is maintaining two branches in parallel. The v1.12.x line ships tagged releases with no published notes — the feed carries only the version string and a CI skip marker — while v3.0.0 moves through numbered betas whose changelogs are raw PR lists dominated by theming, layout, and CSS variable work. Nothing in the recent window adds a question type or changes the library's public surface.
◆ Where it's heading
v3 reads as a design-system rewrite rather than a feature release: SCSS variable refactors, theme tokens for dropdown menus and component radii, and repeated theme update passes recurring across consecutive betas. The v1 line is in pure upkeep, tagged every one to two weeks with nothing documented. The branches are not converging yet — v3 betas still carry Merge/v2 commits pulling stable-branch fixes forward.
◆ Prediction
The beta numbering and continued styling churn suggest a stable v3.0.0 is not close; the betas would have to shift from CSS refactors to migration and API notes first. What these entries do not show is whether the v1 line gets a documented final release or simply stops being tagged.
