# Omnia vs Dify

> Omnia gates every version on simulated users, rolls out in steps with automatic rollback, and gives each team its own workspace in one cluster. Dify’s release is a manual preview, a publish button and a restore that overwrites your draft.

## Built it in Dify? Omnia tests each version before it’s published.

Omnia is built for the release side, and for a platform team running agents for everyone else. Dify’s release is a manual preview, a publish button and a restore that overwrites your draft.

## When it matters: A published support agent starts misrouting refunds.

**On Omnia:** The new version was on its first step of traffic. The misrouted refunds moved the metrics, promotion stopped and the previous version took over. The engineer’s work in progress is untouched, and the failing conversation is now a regression scenario. (Omnia docs: https://omnia.altairalabs.ai/tutorials/progressive-rollouts/)

**On Dify:** Restoring a version replaces your current draft completely, and you publish it again. Restore is on paid plans. Staged rollout isn’t documented. (source: https://docs.dify.ai/en/cloud/use-dify/build/version-control)

## Tested before it publishes

In place of a preview you click through, simulated users take the agent through its real tools, some of them hostile and some on the phone. Publishing waits on the result. (Omnia docs: https://promptarena.altairalabs.ai/arena/explanation/scenario-design/)

Dify: Preview mode is the final check before you publish. Built-in evaluation isn’t documented; Dify points to third-party tools. (source: https://docs.dify.ai/en/cloud/use-dify/build/new-agent/build)

## A rollout with a brake

Each step of traffic waits on the metrics, and a conversation that started on the old version finishes there. *(enterprise)* (Omnia docs: https://omnia.altairalabs.ai/tutorials/progressive-rollouts/)

Dify: Publish an update to make the draft live; restore an old version into the draft to roll back. (source: https://docs.dify.ai/en/cloud/use-dify/build/version-control)

## One cluster, every team

Workspaces give each team its own agents, RBAC and network isolation in a shared cluster, with budgets per workspace. All of it is in the free core. (Omnia docs: https://omnia.altairalabs.ai/how-to/workspaces/manage-workspaces/)

Dify: The community edition has a single workspace, and its licence forbids operating a multi-tenant environment without written authorisation. (source: https://github.com/langgenius/dify/blob/main/LICENSE)

## Questions

**Is Dify open source?**

Its licence is a modified Apache 2.0 that forbids operating a multi-tenant environment without authorisation and protects the console logo. Omnia is proprietary and free to run; the test harness underneath it, PromptArena, is Apache 2.0.

**Can I keep building in Dify and run on Omnia?**

Omnia runs agents from other frameworks under its own policy and testing, and its scenarios run against any endpoint you can reach, including a published Dify app.
