Best agent harnesses and coding agents · All 713 harnesses comparisons

Which one, for what

Droid CLI C

Best for Teams that want a terminal coding agent with tiered autonomy, command rules and an optional sandbox, and that will pay for a Factory plan.

Ahead on

  • Schema & documentation, 79 against 58
  • Security & auth, 63 against 56
  • Maintenance & community, 79 against 49
  • Transparency & trust, 64 against 51

Also in its favour

  • No incidents deducted, where mini-swe-agent loses 4 points for them

Watch for

No free tier or trial was found. Plans start at $20 a month and included usage is stated only as rolling rate limits without numbers

mini-swe-agent C

Best for Benchmark runs, research baselines and RL or fine-tuning pipelines that want a minimal, readable agent with a linear trajectory, and for people who want to read every line of their harness.

Ahead on

  • Reliability, 70 against 49
  • Payments & pricing, 60 against 10

Also in its favour

  • No key needed to call it
  • Free to start without a card
  • Open source

Watch for

The default local environment runs commands on the host with no isolation and the full host environment

Verdicts

Droid CLI

droid exec is read-only unless --auto raises the autonomy level, with command rules, an optional kernel-enforced sandbox, JSON output and documented exit codes. No free tier, status page or security.txt was found, the source is closed, and usage metrics go to Factory by default.

mini-swe-agent

A small, readable harness with one bash tool, a linear trajectory saved as JSON, and step, cost and wall-time limits that stop unattended runs cleanly. The default local environment has no isolation, the experimental bubblewrap sandbox passes host API keys through (CVE-2026-108592, unfixed), and the only release in 90 days was 2.4.6 on 23 July 2026.

Before you call either

Droid CLI

  1. Set FACTORY_API_KEY (starts fk-) from the API keys page in Factory settings for headless runs. Interactive use signs in through a browser
  2. Start with droid exec and no flags for analysis. Add --auto low for edits and --auto medium for installs, tests and local commits
  3. Use --output-format json and read is_error, num_turns and session_id. Treat a non-zero exit code as failure
  4. Set sandbox.enabled to true before running on untrusted code. In droid exec a sandbox violation is denied without a prompt
  5. Pin the version in CI with npm install -g droid@<version>, or set FACTORY_DROID_AUTO_UPDATE_ENABLED=false on standalone installs, which update themselves

mini-swe-agent

  1. Run with -y --exit-immediately for unattended use. Without --exit-immediately it waits for input when the agent finishes
  2. Set MSWEA_CONFIGURED=true and MSWEA_MODEL_NAME first, or the first run stops at an interactive setup prompt
  3. Read info.exit_status in the -o trajectory file. A run that hits its limits still exits normally
  4. For untrusted repositories use -c mini.yaml -c environment.environment_class=docker -c environment.image=<image>. The local and bubblewrap environments both expose host variables
  5. Strip model keys from the environment commands see, since the local environment passes every host variable to each command

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
