Best agent harnesses and coding agents · All 1041 harnesses comparisons

Which one, for what

OpenAI Agents API BB

Best for Teams that want OpenAI to run the agent loop, with sandboxes, MCP tools and subagents, and are fine with a beta API, US-only data residency and no Zero Data Retention.

Ahead on

  • Reliability, 60 against 51
  • Schema & documentation, 88 against 81
  • Security & auth, 87 against 58
  • Maintenance & community, 87 against 72
  • Transparency & trust, 85 against 61

Also in its favour

  • Agent-ready, a grade of BB or better
  • A hosted endpoint, with nothing to install
  • No incidents deducted, where Qoder CLI loses 3 points for them

Watch for

Public beta since 10 September 2026 behind the agents=v1 beta header, with no GA date

Qoder CLI C

Best for Developers already on Qoder who want the same agent in a terminal, in CI through a PAT, in Zed through ACP, or embedded through the Agent SDK.

Ahead on

  • Payments & pricing, 35 against 30

Watch for

No local sandbox is documented, and auto mode approves read-only tools on any path

Why the edge

Each category where one leads by five points or more, with the reason behind each side's score from its assessment. The numbers are in the table below; this is what they stand for.

Security & auth OpenAI Agents API +29

OpenAI Agents API 87

Project keys with restricted per-endpoint permissions, service accounts and workload identity, per the openai-api listing; we didn't confirm a key can be limited to /v1/agents (27 of 30). Automatic review for approvals, a sandbox network restricted to a host allowlist, vaults for secrets and a sandbox security guide (17 of 20). The agent reads web pages, MCP results and browser content; the sandbox security guide and approval flow are the mitigations, with no prompt-injection guide of its own found (8 of 15). Tracing, observability and usage per session and admin audit logs (15). SOC 2 Type 2, ISO 27001 family, Bugcrowd bounty and a disclosure policy, per the openai-api listing (20). Not ZDR-eligible and US residency only, recorded under transparency. 27 + 17 + 8 + 15 + 20 = 87.

Qoder CLI 58

Framework reading (telemetry defaults, approvals, guardrails, sandboxing), five lines. Browser sign-in with background refresh, or a PAT created with chosen permissions and an expiry and revocable, plus scoped service accounts for organisations. Usage statistics and AI code statistics are on by default with documented opt-outs, and the privacy policy lets users turn off Share & Improve depending on the plan, without saying which plans or the default (18). Five permission modes, deny over ask over allow across seven rule layers, ask turned into deny in headless runs, a dont_ask mode, trusted directories, protected paths and an administrator switch that disables YOLO. No local sandbox is documented, and auto mode lets an AI classifier decide and approves read-only tools on any path (14). Workspace files can't add auto-mode rules, protected paths stop the agent changing shell startup files or .mcp.json without approval, and network paths always ask on Windows. A project's .qoder/settings.json is still one of the rule layers, and nothing contains a command once approved (9). The enterprise audit log records administrative and configuration events for administrators and says it leaves out prompts, terminal commands, MCP call parameters and CLI execution, and individuals have local session history only (5). qoder.com/enterprise says Qoder is certified to ISO/IEC 27001 and has completed a SOC 2 Type II audit. No security.txt, disclosure policy or bug bounty was found, and fixes appear as one-line release notes without advisories. Graded 12 against the named comparables for ISO 27001 and SOC 2 claims with no disclosure route (fireworks-inference, people-data-labs, launchdarkly), where the 18 October check gave 9 (12). 18+14+9+5+12 = 58. Per the 18 October check, not re-read on 4 November (Qoder's terms bar scraping its Services by automated means, so its sites are paused for this run).

Transparency & trust OpenAI Agents API +24

OpenAI Agents API 85

Closed service with clear terms, Apache-2.0 SDKs (15). Session state retained until deleted, deletable sessions and artifacts, not ZDR-eligible, US residency only, and the data-controls guide agrees; no retention period for artifacts after a sandbox expires (25 of 30). Dated deprecation notices with minimum periods for GA models; a beta API can change faster (15 of 20). Subprocessors and processing countries listed, per the openai-api listing (20). 15 + 25 + 15 + 20 = 75.

Qoder CLI 61

Proprietary, with clear terms from BRIGHT ZENITH PRIVATE LIMITED under Singapore law, and the SDK's LICENSE points to the same terms (15). The privacy policy lists purposes with retention for each (mostly for as long as the account exists), names storage in the United States, Singapore and Japan and names model providers. The terms let the operator use User Content to improve the Services unless Share & Improve is turned off, and the policy says the opt-out depends on the plan. No subprocessor list or DPA was found (14). Dated notices with two weeks' warning for the Lite tier removal (4 to 18 September 2026) and for the credit factor change on 21 September, but no stated deprecation policy (8). Usage statistics and AI code statistics are disclosed as settings with an opt-out, both on by default, and the installer's telemetry isn't described (14). 15+14+8+14 = 51. Per the 18 October check, not re-read on 4 November (Qoder's terms bar scraping its Services by automated means, so its sites are paused for this run).

Maintenance & community OpenAI Agents API +15

OpenAI Agents API 87

Closed API. Last dated change 16 October 2026, Ultrafast mode and document skills (30). Four dated changelog entries in the 57 days since release, 10 September, 29 September, 9 October and 16 October (20). Changelog and help centre, as the openai-api listing reads them (12 of 15). Official SDKs carry beta.agents (15). SDK CI, per the openai-api listing (10). 30 + 20 + 12 + 15 + 10 = 87.

Qoder CLI 72

1.1.73 on 16 October 2026, 19 days before 4 November (30). 74 dated CLI versions between 20 July and 16 October 2026, well over three of them after 6 August (20). No public issue tracker. A Discourse forum with bug-report and feature-request categories, where 15 of the 29 bug reports on the first page had no reply when read on 18 October (7). Current official SDKs, @qoder-ai/qoder-agent-sdk 1.0.53 on 15 October and qoder-agent-sdk 1.0.15 on PyPI on 23 September 2026 (12). No public CI. npm versions carry registry signatures and the install script checks a SHA-256 (3). 30+20+7+12+3 = 72. Per the 18 October check, not re-read on 4 November (Qoder's terms bar scraping its Services by automated means, so its sites are paused for this run). npm and PyPI were not reachable for newer versions.

Reliability OpenAI Agents API +9

OpenAI Agents API 60

Read as a hosted API. status.openai.com has an Agents component under APIs (20). Since release on 10 September (57 days, not 90), the feed names the Agents API in a degraded-performance incident on 14 September, the elevated errors across ChatGPT, Codex and the API on 29 September (the openai-api listing reads that one as a major, 17:52 to 23:14 UTC), computer use issues and degraded workspace agents on 6 and 7 October, degraded performance across the APIs for 22 minutes on 21 October, and overbilling for hosted containers on 19 September. One major, the rest minor (10). Rate limits come from the shared guide, published per tier and model with headers, and the errors page adds a Files API allowance on session creation (15). 429 and 503 guidance with Retry-After, capped backoff and a check-then-retry procedure for turns (15). The Scale Tier SLA in the openai-api listing isn't shown to cover a beta API (0). Public beta behind the agents=v1 header (0). 20 + 10 + 15 + 15 + 0 + 0 = 60.

Qoder CLI 51

Local-package reading, the same as the other closed-source harnesses. An install script for macOS, Linux and Windows on arm64 and amd64 that checks a SHA-256 from a manifest on the same download host, and an npm package with Node.js 20 or later stated (20). No public CI or test suite, since no source is published (0). We found no public issue tracker for the CLI. The forum's bug-reports category, shared by every Qoder product, had 116 new topics in the month to 18 October, and 15 of the 29 topics on its first page had no reply. A few named the CLI (8). Versions are semver-shaped and every release is dated in the release notes, but removals such as /goal take in 1.1.11 shipped in patch versions without a breaking-change label (8). 1.0.0 on 20 May 2026, now 1.1.73 (15). 20+0+8+8+15 = 51. Per the 18 October check, not re-read on 4 November (Qoder's terms bar scraping its Services by automated means, so its sites are paused for this run).

Schema & documentation OpenAI Agents API +7

OpenAI Agents API 88

The reference is linked from the overview and the SDKs carry beta.agents types; we didn't confirm /agents/sessions in OpenAI's public OpenAPI file, so 15 of 25. llms.txt with every Agents API page and Markdown twins (10). The overview, architecture page and the agents guide that compares the Agents API, Agents SDK and Responses API say when to use it (20). Typed configuration with enumerated container sizes, network modes and environment types (13 of 15). Examples in six languages and an errors page with codes per HTTP status, turn and session (15). Dated changelog entries and a versioned beta header (15). 15 + 10 + 20 + 13 + 15 + 15 = 88.

Qoder CLI 81

Framework reading. A CLI reference with types and defaults for every flag, a settings reference with types and defaults, TypeScript declaration files and a Python reference for the SDK, and Result and error-code tables. No schema for the stream-json events was found (16). docs.qoder.com/llms.txt indexes every page with a Markdown twin, and robots.txt allows both (10). The permissions page states what each mode does and is best for, what headless runs do with ask, and which actions skip the auto classifier (17). Permission modes and output formats are enums and rules have a fixed syntax (12). CI examples, an SDK error page with exit codes 0, 1, 41, 42, 44, 52, 53, 54 and 130, Result subtypes and a troubleshooting index. Code 44 names a sandbox the docs don't describe (14). Dated release notes for the CLI and the SDK, though the SDK notes stop at 1.0.41 on 15 September while npm has 1.0.53, and the CLI reference still names the removed lite model (12). 16+10+17+12+14+12 = 81. Per the 18 October check, not re-read on 4 November (Qoder's terms bar scraping its Services by automated means, so its sites are paused for this run).

Payments & pricing Qoder CLI +5

OpenAI Agents API 30

No machine payment protocol (0). Model, tool and container prices published without a login, and no fee for the API itself (20). The Free tier reading of the openai-api listing, half (10). Sign-up in a browser (0). 0 + 20 + 10 + 0 = 30.

Qoder CLI 35

Harness reading of the published rubric, scored on the Qoder subscription the CLI needs. No payment protocol (0). Plan prices, the Credit Pack price ($20 for 1,500 credits) and per-model credit factors are public in the docs without a login. qoder.com/pricing is disallowed by robots.txt and wasn't read (20). A Free plan with basic models for a limited number of messages and a 14-day Pro trial with 300 credits. We found no statement on whether a card is needed (15). A person signs in through a browser, and a PAT is created by hand at qoder.com/account/integrations (0). 0+20+15+0 = 35. Per the 18 October check, not re-read on 4 November (Qoder's terms bar scraping its Services by automated means, so its sites are paused for this run).

Verdicts

OpenAI Agents API

OpenAI's hosted agent runtime, the Codex harness behind one session call, with MCP, functions, web search, computer use, subagents and sandboxes on OpenAI or your own infrastructure. Documentation, errors and SDKs are thorough. It's still public beta, can't use Zero Data Retention and keeps data in the United States only.

Qoder CLI

A closed-source terminal agent with a documented headless mode, an ACP server, typed TypeScript and Python SDKs and near-daily releases. Permission rules and modes are detailed, but no local sandbox is documented, usage statistics are on by default, and security fixes appear only as one-line release notes with no advisories or disclosure policy.

Before you call either

OpenAI Agents API

  1. POST https://api.openai.com/v1/agents/sessions with a project key and the header OpenAI-Beta: agents=v1, or use client.beta.agents in the SDKs
  2. Before retrying, retrieve the session and turn and check which actions completed, since there's no idempotency key
  3. Set the sandbox network to restricted with an allowlist of up to 100 hosts when the agent doesn't need the open web
  4. Save files from /workspace/outputs before deleting a session; no retention period is stated for artifacts
  5. Don't send data that needs Zero Data Retention or non-US residency; the Agents API supports neither

Qoder CLI

  1. Set QODER_PERSONAL_ACCESS_TOKEN in CI. The browser sign-in can't complete in a headless run
  2. Pass --permission-mode with --allowed-tools in headless runs. Every ask is denied, and --yolo removes all checks
  3. Set --max-turns on unattended runs, and branch on exit codes 41 (authentication) and 53 (turn limit)
  4. Set privacy.usageStatisticsEnabled and aiCodeStatistics.enabled to false in ~/.qoder/settings.json if usage data must stay local
  5. Don't pass --model lite. The Lite tier was removed on 18 September 2026 and headless requests naming it fail
