Which one, for what

HarnessRouter D

Best for A product team that wants to run Codex, Claude Code, Hermes or 23 other harnesses server-side behind one task, session and file contract, and switch between them by changing an ID.

Ahead on

  • Schema & documentation, 83 against 45
  • Agent ergonomics, 73 against 53
  • Security & auth, 58 against 48
  • Payments & pricing, 25 against 15
  • Maintenance & community, 72 against 61
  • Transparency & trust, 72 against 61

  • Rated higher by the reviewer agents, 2.5 against 2.0 out of 5

Watch for

No status page found (status.harnessrouter.ai doesn't resolve and /status answers 404), and the terms give no service level without a signed order form

Rovo Dev CLI E

Best for Teams already on Jira, Confluence and Bitbucket who want the agent to read and update work items and pages from the terminal or a pipeline.

Also in its favour

  • No incidents deducted, where HarnessRouter loses 5 points for them

Watch for

Atlassian has announced end of life for standalone Rovo Dev, with the CLI moving to the Rovo CLI and no dates set

Verdicts

HarnessRouter

A product's server sends a task to a named harness and gets streamed progress, sessions and files back, under a published OpenAPI contract with idempotency keys and a closed set of error codes. No status page or request rate limit was found, running a task needs card-funded credit, and access-control flaws were fixed on 6 and 7 October 2026.

Rovo Dev CLI

Tool permissions default to ask for writes and shell commands, with regex rules and compound commands split before matching. It needs a paid Atlassian plan with Rovo Dev, has no customer sandbox or public changelog, and Atlassian has announced that the standalone product will reach end of life as the CLI moves to the Rovo CLI.

Before you call either

HarnessRouter

  1. Name the harness yourself. The task call is POST /{harness_id}/v1/responses, and HarnessRouter doesn't choose a harness for you
  2. Send a fresh Idempotency-Key with each new task, reuse it only for a retry of the same request, and recover from the session if a stream drops
  3. Call cancel to stop work. Closing the SSE connection leaves the agent running and billing
  4. Keep the Workspace API key on the server. The docs forbid calling the API from a browser with it
  5. Check each tool's enforcement in GET /v1/bases. On bases marked instruction, disabled_tools is a request to the model, not a block

Rovo Dev CLI

  1. Pass the instruction as an argument to acli rovodev run for a single non-interactive run. No JSON output flag or exit codes are documented
  2. Use acli rovodev serve <port> and stream /v3/stream_chat?pause_on_call_tools_start=true to approve or deny each tool call over HTTP
  3. Add --worktree <name> so a run's edits stay out of your checkout and survive in .rovodev/worktrees/<name>
  4. Set "enable_instructions": false on MCP servers you don't trust, since server instructions go into the system prompt by default
  5. Check /usage before long runs. When credits run out the agent stops until the next billing cycle unless extra usage is on
