Mamba vs SurveyJS
A side-by-side editorial comparison of Mamba and SurveyJS — release velocity, themes, recent moves, and the top alternatives to consider.
Mamba vs SurveyJS: at a glance
What is Mamba?
Mamba is adding the reproducibility controls conda users have been asking of the solver.
The 2.9.0 release candidates introduce two user-facing controls: excluding builds newer than a given timestamp with --exclude-newer, and opting out of link script execution. Around them sit fixes with an operational bent, leaving permissions on shared package cache directories alone, explaining missing packages when string ids collide with solvables, and static linking corrections. The earlier alpha in this window is entirely bug fixes to noarch Python entry point linking and root package expansion.
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.

◆ Current state
The 2.9.0 release candidates introduce two user-facing controls: excluding builds newer than a given timestamp with --exclude-newer, and opting out of link script execution. Around them sit fixes with an operational bent, leaving permissions on shared package cache directories alone, explaining missing packages when string ids collide with solvables, and static linking corrections. The earlier alpha in this window is entirely bug fixes to noarch Python entry point linking and root package expansion.
◆ Where it's heading
Both new options point the same way: making an environment solve predictable and less trusting. A timestamp cutoff turns a solve into something reproducible after the fact, and disabling link scripts removes arbitrary code execution from installation. The bug fixes concentrate on shared and multi-user installs, which suggests the pressure is coming from environments where one package cache serves many users.
◆ Prediction
With a timestamp cutoff and a link-script opt-out both landing in the same release, the direction is toward solves that can be audited and repeated; further work most likely continues on the shared-cache and permissions handling these fixes keep touching.
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.
