Best agent harnesses and coding agents · All 713 harnesses comparisons
Which one, for what
Best for A technical owner who wants an agent with its own Linux machine, reachable from Telegram, WhatsApp or email, with scheduled tasks and editable memory.
Ahead on
- Schema & documentation, 64 against 58
- Maintenance & community, 75 against 49
Watch for
No approval step before shell commands, file changes or outgoing messages. Tool Access defaults to allow
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 57
- Agent ergonomics, 69 against 62
Also in its favour
- Free to start without a card
Watch for
The default local environment runs commands on the host with no isolation and the full host environment

Verdicts
Agent Zero
Self-hosted under the MIT licence, with nine releases in the 90 days to 12 October 2026 and breaking changes listed in the release notes. The agent runs shell commands in its container with no approval step, the web interface has no login by default, and five CVEs from the past year have no published GitHub advisory.
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
Agent Zero
- Set a UI login and password in Settings before publishing the port or opening a tunnel. The default has none
- Fill
allowed_users,allowed_numbersorsender_whitelistbefore enabling a channel. An empty list accepts every sender - Enable the Infection Check plugin when the agent reads mail, web pages or MCP results. It ships disabled
- Run v2.12 or later. It fixes a Telegram webhook authentication bypass and a WhatsApp media path traversal
- Call
POST /api_messagewith theX-API-KEYheader. The token changes when the UI login or password changes
mini-swe-agent
- Run with
-y --exit-immediatelyfor unattended use. Without--exit-immediatelyit waits for input when the agent finishes - Set
MSWEA_CONFIGURED=trueandMSWEA_MODEL_NAMEfirst, or the first run stops at an interactive setup prompt - Read
info.exit_statusin the-otrajectory file. A run that hits its limits still exits normally - 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 - Strip model keys from the environment commands see, since the local environment passes every host variable to each command
