Aim
An experiment tracker grinding on storage performance — and quiet for over a year.
A side-by-side editorial comparison of Plotly and Zipkin — release velocity, themes, recent moves, and the top alternatives to consider.
Plotly is turning its cloud into a metered compute platform with an enterprise on-ramp.
Plotly now ships on two tracks. Plotly Studio, the desktop AI app-builder, releases every one to two weeks and has spent v0.0.80 through v0.0.85 on credential handling, reasoning transparency and per-user personalization. Plotly Cloud is the louder track: since late May it has added viewer-seat pricing, domain verification, per-app compute modes with credit-metered billing, and customer-owned domains with managed TLS.
Zipkin's last release was January 2025 — a dependency bump, and then nothing.
The recent history is three consecutive maintenance releases whose entire content is dependency and base-image updates: 3.4.3 aligned Maven versions with the Docker images, 3.4.2 and 3.4.1 moved Spring Boot, Netty, Micrometer, Armeria, Alpine and the JRE forward to clear CVEs. The last release carrying a feature was 3.4 in May 2024, which added OpenSearch v2 as a storage backend using the existing ES_-prefixed environment variables.

The Cloud releases are assembling the standard pieces of a hosting business in order — identity first (domain verification, explicitly framed as the step before SSO), then billing (viewer seats, then metered compute credits), and now production-grade serving (custom domains, automatic certificate renewal). Studio is being hardened as the authoring front end that feeds it: Universal Deployment pushed beyond Dash apps, credentials saved once and reused, and a Winget channel to widen Windows installs. The two tracks converge on one funnel — author in Studio, deploy to Cloud, pay by compute consumed.
The Domain Verification entry names SSO as the next step and places it in the Enterprise tier, so single sign-on is the most likely Cloud release next. Studio should hold its one-to-two-week cadence, with the pending Winget approval landing inside the stated one-to-two-week window.

This is a project in preservation rather than development. The pattern across the window — feature in May 2024, then three releases of purely defensive dependency work, then silence since January 2025 — describes a mature tracing server being kept safe to run rather than extended. The distributed-tracing work that would once have landed here now largely happens in OpenTelemetry, which Zipkin interoperates with rather than competes against.
The feed has produced nothing for nineteen months, so the honest read is that no next release is scheduled. If one comes, the shape of the last three says it will be another dependency and base-image refresh rather than new capability.
