T3 Code D

Best for Developers who want one app, including on their phone, to drive several coding agents they already pay for.

Ahead on

  • Payments & pricing, 60 against 35

Also in its favour

  • No key needed to call it
  • Open source
  • No incidents deducted, where Qoder CLI loses 3 points for them

Watch for

Usage data on by default, with hashed OpenAI and Claude account identifiers, and relay traces to Axiom

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.

Schema & documentation Qoder CLI +26

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).

T3 Code 55

Harness reading. User docs in the repository (managed policy, handoffs, providers, telemetry), AGENTS.md for contributors, a server other clients connect to (55).

Payments & pricing T3 Code +25

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).

T3 Code 60

Free self-hosted software with nothing to buy, so 0 for a protocol and 20 each for public pricing, a free tier and onboarding with no sign-up, 60.

Security & auth Qoder CLI +23

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).

T3 Code 35

Harness reading. Product usage events go by default to ingest.t3.codes and PostHog, with hashed identifiers for your T3 Connect, OpenAI and Claude accounts, and relay traces to Axiom, which can include machine names and error text. Off with T3CODE_TELEMETRY_ENABLED=false or a managed policy. Disclosed in docs/user/telemetry.md, not the README (10 of 30). Permission modes and managed policies (12 of 20). No prompt-injection guidance (5). No audit log (5). No security policy file found (3). 10 + 12 + 5 + 5 + 3 = 35.

Agent ergonomics Qoder CLI +20

Qoder CLI 80

Framework reading, adapted to a harness driven by a pipeline. --tools, --allowed-tools and --disallowed-tools restrict built-in tools, and --strict-mcp-config with --allowed-mcp-server-names limits MCP servers. Nothing on deferred MCP tool loading was found (18). text, json and stream-json output, --max-turns, --max-output-tokens and --no-session-persistence (16). Distinct exit codes for authentication, input, configuration, turn-limit and tool failures, and SDK Result subtypes with error codes (16). --continue, --resume, --session-id, --fork-session, SDK checkpoints with rewind, and --max-model-request-retries (15). Official SDKs in TypeScript and Python, an ACP server, and headless runs that need only a PAT and a permission flag (15). 18+16+16+15+15 = 80. 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).

T3 Code 60

Harness reading. Remote control from phone or browser, portable handoffs between providers and managed policies for teams (60).

Transparency & trust Qoder CLI +10

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).

T3 Code 51

MIT (30). docs/user/telemetry.md lists what is sent and what isn't, but includes hashed third-party account identifiers and the README doesn't mention it (15 of 30). No deprecation policy (5). Disclosed with an opt-out, on by default (12 of 20). 30 + 15 + 5 + 12 = 62.

Reliability Qoder CLI +8

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).

T3 Code 43

Local software. An install script and desktop and mobile apps from the vendor (20). ci.yml and windows-tests.yml run on the repository; pass state not read (15). GitHub issues and pull requests weren't read (GitHub's pages refuse these sessions), so that line is scored absent (0). Stable tags v0.1.5 to v0.1.7 with many nightlies, no changelog file (8). Version 0.1.7 (0). 20 + 15 + 0 + 8 + 0 = 43.

How the scores have moved

Verdicts

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.

T3 Code

A fast-moving open-source way to run and steer several coding agents from desktop, browser or phone, using the subscriptions you already have. It's pre-1.0, and it sends usage data by default, including hashed identifiers for your OpenAI and Claude accounts, with the opt-out documented outside the README.

Before you call either

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

T3 Code

  1. Set T3CODE_TELEMETRY_ENABLED=false before starting the server if you don't want usage events sent
  2. Install and log in to at least one provider CLI first, such as codex login or claude auth login
  3. Use a managed policy to fix settings across a team
