Is Bloom or Onyx better for AI endpoint control?

Neither is scored on this site. Bloom describes 0 of four product control types and Onyx 3 on the pages we read, and they differ on 11 recorded facts. Which fits depends on the AI tools people use, your devices, where the work happens and whether you block or guide; the finder checks those.

Which of the two decides on a tool call before it runs?

Bloom: Partly. Onyx: Matches. Warn or ask: Bloom Not in our sources, Onyx Matches.

Do Bloom or Onyx publish prices?

Bloom: Not published. Onyx: Not published.

Bloom vs Onyx: AI endpoint control facts side by side

Short answer

Bloom describes 0 of the four product control types on the pages we read and Onyx describes 3; they differ on on-device control, browser extension and AI or MCP gateway. On decisions, Bloom describes some control over tool calls and Onyx decides on a tool call before it runs. We do not score either; the right choice depends on the AI tools people use, your devices, your current stack and whether you block or guide.

Choose Bloom if

Your first worry is unvetted extensions and packages arriving on developer machines
You want an inventory of everything on the endpoint before you write AI-specific rules

Choose Onyx if

You want masking or steering rather than only allow or block
AI use spans the browser, desktop apps, coding tools and cloud workloads

Which limits should you check?

Bloom

Deployment method and pricing are not published.
