Arize Phoenix vs RAGFlow: at a glance
What is Arize Phoenix?
Phoenix evals pins out a compromised LiteLLM release and the emSign root.
Arize Phoenix is shipping near-daily releases across its server, Python evals and TypeScript packages. The past week was mostly fixes and dependency hygiene: evals 3.9.3 excluded the compromised LiteLLM 1.107.0 and required a certifi build that distrusts the emSign root, and later patches refreshed playground presets and evals kwargs handling. Server 20.25 and 20.26 mainly carried the team's internal issue-to-PR agent tooling, plus a service.version attribute on Phoenix's own OpenTelemetry resource.
What is RAGFlow?
RAGFlow's dev builds settle permission ownership while the rest is migrations and test plumbing.
RAGFlow is shipping several dev builds a day ahead of its v1.0 line. This week's builds fix a migration, update the base DB model, add a model-group hook, start the standalone DeepDoc server before infrastructure, and keep enterprise test placeholders in the open-source tree. An earlier 10-23 build aligned resource and agent ownership with the new permission model.

Arize Phoenix
5.0AI-ML-PLATFORMS
Phoenix evals pins out a compromised LiteLLM release and the emSign root.
◆ Current state
Arize Phoenix is shipping near-daily releases across its server, Python evals and TypeScript packages. The past week was mostly fixes and dependency hygiene: evals 3.9.3 excluded the compromised LiteLLM 1.107.0 and required a certifi build that distrusts the emSign root, and later patches refreshed playground presets and evals kwargs handling. Server 20.25 and 20.26 mainly carried the team's internal issue-to-PR agent tooling, plus a service.version attribute on Phoenix's own OpenTelemetry resource.
◆ Where it's heading
Phoenix keeps widening tracing coverage through integration pages (Pipecat, Microsoft Agent Framework) and its TypeScript evals, which now run classifiers on AI SDK decision models. The core product sees small, frequent fixes rather than large features right now, and supply-chain pinning has become part of the release routine.
◆ Prediction
The TypeScript decision-model support is pinned to experimental AI SDK versions, so expect follow-up patches as that API changes.
RAGFlow
7.5AI-ML-PLATFORMS
RAGFlow's dev builds settle permission ownership while the rest is migrations and test plumbing.
◆ Current state
RAGFlow is shipping several dev builds a day ahead of its v1.0 line. This week's builds fix a migration, update the base DB model, add a model-group hook, start the standalone DeepDoc server before infrastructure, and keep enterprise test placeholders in the open-source tree. An earlier 10-23 build aligned resource and agent ownership with the new permission model.
◆ Where it's heading
The permission work that began with the schema migration and tenant roles is wrapping up with ownership rules, while the Go rewrite gets refactors for testability and startup order. The keep-EE-placeholders change shows the open-source and enterprise editions sharing one tree.
◆ Prediction
Expect a v1.0.0 release candidate that packages tenant roles and permissions, with model groups as a likely new configuration surface.
