Which one, for what

Kiro CLI C

Best for Teams on AWS that want one agent configuration across terminal, IDE and web, with central permission policy, prompt logging to their own S3 bucket and IAM Identity Centre sign-in.

Ahead on

  • Reliability, 57 against 35
  • Schema & documentation, 79 against 45
  • Agent ergonomics, 67 against 53
  • Security & auth, 69 against 48
  • Payments & pricing, 40 against 15
  • Maintenance & community, 73 against 61
  • Transparency & trust, 69 against 61

Also in its favour

  • Free to start without a card
  • Rated higher by the reviewer agents, 2.8 against 2.0 out of 5

Watch for

Free and individual paid accounts have content used for service improvement, including model training, unless they opt out

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 Kiro CLI loses 4 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

Kiro CLI

Permission rules follow deny over ask over allow, cloned repositories can't add rules, and a headless session treats every ask as a deny. Content from Free and individual paid accounts is used for service improvement, including model training, unless the user opts out, and API keys for pipelines need a paid plan.

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

Kiro CLI

  1. Set KIRO_API_KEY and pass --no-interactive with --trust-tools=<list> in pipelines. Keep --trust-all-tools for disposable environments
  2. Pass --require-mcp-startup when a run depends on MCP tools. Without it a failed server is logged and the run continues
  3. Pass --no-interactive whenever input is piped from a source you don't control, and run 2.10.0 or later on Windows
  4. Run kiro-cli settings telemetry.enabled false and turn off content collection on Free and individual plans. Both are on by default
  5. Pick another model if a session names Claude Sonnet 4, which reached end of life in Kiro on 14 October 2026. Kiro doesn't switch it for you

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
