mini-swe-agent vs Warp (Warp Agent CLI and the Oz Agent API)
Warp (Warp Agent CLI and the Oz Agent API) scores 59.8 (C) on agent readiness against mini-swe-agent's 56.7 (C), and leads in 3 of 7 scored categories. mini-swe-agent leads on reliability and payments & pricing. Both do agent harnesses.
Best agent harnesses and coding agents · All 713 harnesses comparisons
Which one, for what
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 52
- Payments & pricing, 60 against 20
Also in its favour
- No key needed to call it
- 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
Warp (Warp Agent CLI and the Oz Agent API) C
Best for Teams that want one agent across an interactive terminal session and API-started cloud runs, including Claude Code and Codex runs on Warp's infrastructure or their own workers.
Ahead on
- Schema & documentation, 89 against 58
- Maintenance & community, 84 against 49
- Transparency & trust, 72 against 51
Watch for
The warp CLI has no print or headless mode. Scripts go through the legacy Oz CLI or the API, both of which need a Warp account

Verdicts
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.
Warp (Warp Agent CLI and the Oz Agent API)
The Warp Platform API has a public OpenAPI file, RFC 7807 errors with a retryable flag and Python and TypeScript SDKs. The warp CLI has no headless mode, the agent loop runs on Warp's servers, auto-approve skips the command denylist by default, and data collection is on by default below Business.
Before you call either
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
Warp (Warp Agent CLI and the Oz Agent API)
- For unattended work, call
POST https://app.warp.dev/api/v1/agent/runswithAuthorization: Bearer $WARP_API_KEY. ThewarpCLI is interactive only - Use an agent key, scoped to one cloud agent and given an expiry, for CI rather than a personal key. Keys are created in the Oz web app or the Warp app
- Set
auto_approve_bypasses_command_denylist = falseunder[agents.warp_agent.other]before startingwarp --auto-approve - Read
codeandretryablein error bodies. A 429resource_unavailablemeans capacity is full and the platform retries the task itself - Pin a version with
WARP_TUI_VERSIONat install, or setgeneral.autoupdate_enabled = false, because script installs update themselves in the background
