Dify vs Promptfoo
A side-by-side editorial comparison of Dify and Promptfoo — release velocity, themes, recent moves, and the top alternatives to consider.
Dify vs Promptfoo: at a glance
What is Dify?
Dify 1.19 traces workflows layer by layer, down to the LLM calls inside nested tools.
Dify 1.19.0 sends nested workflow traces to external observability tools: steps inside called Workflow Tools now appear beneath the span that invoked them, with prompts, responses and token usage attached. It also makes Workflow Tools portable inside App packages, adds Skill Hub automation and easier Agent file uploads. It follows 1.18.0, which let an Agent node pick the next workflow branch and introduced the .ifpkg package and difyctl CLI.
What is Promptfoo?
Promptfoo's feed has gone quiet except for small fixes to its code-scan action.
The newest entries are code-scan GitHub Action patches: 0.2.1 updates type definitions and 0.2.2 mints the OIDC token after the CLI installs. The main evaluator's last visible release, 0.121.20 in July, added Claude Opus 5, Kimi K3 and websocket URL templating, following a run of releases that tracked each new frontier model.

Dify
6.3AI-ASSISTANTS
Dify 1.19 traces workflows layer by layer, down to the LLM calls inside nested tools.
◆ Current state
Dify 1.19.0 sends nested workflow traces to external observability tools: steps inside called Workflow Tools now appear beneath the span that invoked them, with prompts, responses and token usage attached. It also makes Workflow Tools portable inside App packages, adds Skill Hub automation and easier Agent file uploads. It follows 1.18.0, which let an Agent node pick the next workflow branch and introduced the .ifpkg package and difyctl CLI.
◆ Where it's heading
After several releases that made agents act inside workflows, Dify is now making that behaviour inspectable and portable. Tracing nested calls and packaging tools with apps are what teams need before trusting agent-routed workflows in production.
◆ Prediction
Expect more observability and evaluation work around agent decisions, such as tracing why an Agent chose a route. Packaging will likely extend to more component types as .ifpkg becomes the deployment unit.
Promptfoo
5.0AI-ASSISTANTS
Promptfoo's feed has gone quiet except for small fixes to its code-scan action.
◆ Current state
The newest entries are code-scan GitHub Action patches: 0.2.1 updates type definitions and 0.2.2 mints the OIDC token after the CLI installs. The main evaluator's last visible release, 0.121.20 in July, added Claude Opus 5, Kimi K3 and websocket URL templating, following a run of releases that tracked each new frontier model.
◆ Where it's heading
The evaluator's rhythm is provider coverage plus red-team strategies, and the code-scan action is maintained on its own track. The feed shows no evaluator release since July, which may be a feed gap rather than a pause.
◆ Prediction
If the evaluator is still shipping, the next visible entry will likely add the latest frontier models; the feed doesn't show whether it stopped.
