The JetBrains AI Terms of Service (version 2.1, effective 30 September 2025) name AI Assistant and Junie, though the Junie EAP terms from December 2024 still call Junie a plugin (15). The terms rule out training on inputs without consent and list AI subcontractors with 30 days' notice of new ones (page updated 29 September 2026, naming OpenAI, Google, Anthropic and SpaceXAI for Junie). The AI FAQ says nothing persists unless detailed data collection is on, retained up to a year, and that it's on by default for non-commercial licences. Security monitoring keeps data for an unstated limited period (22). The terms promise 30 days' email notice before JetBrains AI is discontinued, but Junie Lite's model may change without notice and model aliases change without a stated period (10). A per-run override for anonymous statistics is documented, with no stated default and no list of what is sent (10). 15+22+10+10 = 57. Per the 18 October check, not re-read on 4 November, because JetBrains' website terms bar robots and data mining on its sites.\n- 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.\n\n### Security \u0026 auth: Junie CLI +21\n\n- Junie CLI (56): Framework reading (telemetry defaults, approvals, guardrails, sandboxing), five lines. A browser login, a long-lived Junie API key with no scopes we found, or provider keys passed as flags or environment variables. The CLI's statistics default isn't stated (13). The allowlist asks before terminal commands, MCP tools, edits outside the project, reads outside it and secret files, and checks every part of chained, nested and multi-line commands. Brave mode is interactive only. Sandbox mode limits writes and hides `~/.ssh`, but it's EAP-only, off by default, missing on Windows, and leaves the network open by default (12). Interactive runs keep an untrusted project's MCP servers, hooks and skills unloaded and a project can't widen the sandbox, but one-shot, piped, ACP and Gateway runs trust every project by design, and the docs say to run them only in trusted projects (9). `/usage` shows per-session cost and sessions are stored, and PreToolUse hooks in batch runs can log or block tools, but they're EAP, and no audit log for the CLI was found (7). A coordinated disclosure policy (updated 10 October 2026) and a security.txt contact, CVEs JetBrains publishes as a CVE numbering authority (three for Junie in cvelistV5) and a fixed-issues page, discretionary rewards with no formal bounty, and SOC 2 per the Junie homepage. The repository has no SECURITY.md, per a clone on 4 November (15). The docs, policy and homepage readings are per the 18 October check, not re-read on 4 November, because JetBrains' website terms bar robots and data mining on its sites. 13+12+9+7+15 = 56.\n- 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.\n\n### Payments \u0026 pricing: T3 Code +18\n\n- Junie CLI (42): Harness reading of the published rubric. No payment protocol (0). Plan prices and the US$1 credit are public without a login, but per-model credit rates and Junie API key usage rates weren't found (12). Junie Lite is free with a JetBrains account and no card (20). Judgement call. The docs present BYOK keys and custom endpoints such as Ollama as alternatives to a JetBrains sign-in, so a pipeline holding a provider key needs no JetBrains signup, but the headless page says a token is required and a Junie API key is created by hand at junie.jetbrains.com/cli (10). 0+12+20+10 = 42. Per the 18 October check, not re-read on 4 November, because JetBrains' website terms bar robots and data mining on its sites.\n- 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.\n\n### Maintenance \u0026 community: T3 Code +11\n\n- Junie CLI (64): Release 26.11.3 (build 3959.5) added to the release feed on 3 November 2026, read from a clone of JetBrains/junie (30). The release channel added 30 builds between 6 August and 3 November, from 2651.3 on 11 August to 3959.5, and the repository has 1,032 tags created in that window, most of them nightly builds (20). Responsiveness 5 of 25. The 18 October counts of the GitHub tracker and YouTrack came from shields.io badges and YouTrack's JSON API, both struck, so what is left is the dated What's New page and a Discord server, per the 18 October check, with replies unread (5). No SDK and no registry entry. The GitHub Action is at v1 and GitLab CI is documented, and ACP is kept current, per the 18 October check (6). Closed source with no workflow files in the repository, so no CI or dependency health to read. The installer checks sums, and npm sat five weeks behind the release feed on 18 October (3). 30+20+5+6+3 = 64.\n- T3 Code (75): Commits and nightly tags on 6 November 2026 (30). More than three releases in 90 days (20). GitHub issues and pull requests weren't read (GitHub's pages refuse these sessions), so that line is scored absent (0). Current official apps and install script (15). CI on push (10). 30 + 20 + 0 + 15 + 10 = 75.\n\n### Reliability: T3 Code +10\n\n- Junie CLI (33): Local-package reading, the same as the other closed-source harnesses. Install scripts for macOS, Linux and Windows on x86-64 and ARM64, a Homebrew tap and npm, with SHA-256 sums checked against the release feed (update-info.jsonl, read from a clone on 4 November), but the script carries on without a sum for an unlisted version and npm sat five weeks behind at 3110.7.0 on 18 October (17). No public CI or test suite. No source is published and the repository has no workflow files, per a clone on 4 November (0). Crash and regression line 0. The 18 October counts came from shields.io badges and YouTrack's JSON API, both struck in this run, and no first-hand reading of the GitHub tracker or YouTrack is possible today (github.com pages refused, JetBrains hosts paused). What's New dates every build, but entries are one line and no breaking change is called out, and versions are a date plus a build number, per the 18 October check (6). JetBrains said Junie left Beta on 17 June 2026, but the headless page dated 15 October still calls the CLI an EAP, per the 18 October check (10). 17+0+0+6+10 = 33.\n- 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.\n\n### Schema \u0026 documentation: Junie CLI +7\n\n- Junie CLI (62): Framework reading. A CLI reference that lists every flag with examples, documented formats for the allowlist, config.json, custom model profiles and hook payloads, and ACP as the editor protocol. No schema for the json or json-stream output was found, and the OpenAPI covers only update metadata (12). llms.txt exists and claims Markdown by content negotiation, but docs pages came back as HTML with `Accept: text/markdown` and llms.txt doesn't index them (6). Pages say when to use ACP and when not, and how trust works in each launch mode, but the headless page doesn't say what happens when an action needs approval (13). Output formats, effort levels, channels and allowlist actions are enumerated, though the effort values differ between the CLI reference and the model page (11). Examples throughout and nine StopFailure categories in the hooks page, but no exit codes or error format (8). A dated release list and dated docs pages (12). 12+6+13+11+8+12 = 62. Per the 18 October check, not re-read on 4 November, because JetBrains' website terms bar robots and data mining on its sites.\n- 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).\n\n## Score by category\n\n| Category | Weight | Junie CLI | T3 Code | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 33 | 43 | T3 Code +10 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 62 | 55 | Junie CLI +7 |\n| Agent ergonomics | 13% (16.2 this run) | 55 | 60 | T3 Code +5 |\n| Security \u0026 auth | 14% (17.5 this run) | 56 | 35 | Junie CLI +21 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 42 | 60 | T3 Code +18 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 64 | 75 | T3 Code +11 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 77 | 51 | Junie CLI +26 |\n| Negative events | ≤15 | -4 | 0 | |\n| **Total** | | **49 · D** | **51.9 · D** | |\n\n## Facts side by side\n\n| Fact | Junie CLI | T3 Code |\n| --- | --- | --- |\n| Kind | Agent harness | Agent harness |\n| Vendor | JetBrains | T3 Tools Inc. |\n| Hosted endpoint | no (local only) | no (local only) |\n| Transports | | |\n| Auth | OAuth or key | None |\n| Pricing | Freemium | Free |\n| x402 | no | no |\n| Licence | Proprietary, JetBrains s.r.o., all rights reserved, under the JetBrains AI Terms of Service.

Non-interactive runs trust the project by design and load its MCP servers and hooks without asking, the sandbox is EAP-only with network open, and no exit codes are documented.\n\n**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.\n\n## Before you call either\n\n### Junie CLI\n\n1. Run headless only in repositories you trust. One-shot and piped runs load the project's MCP servers, hooks and skills without asking\n2. Set `JUNIE_API_KEY` (from junie.jetbrains.com/cli) or a provider key such as `JUNIE_ANTHROPIC_API_KEY` in CI. The default sign-in opens a browser\n3. Add `--output-format json` or `--json-output-file` to parse results. Check the output, since exit codes aren't documented\n4. Pass `--share-anonymous-statistics false` if no usage statistics may leave the runner\n5. Pin a build with `--use-version` and `--skip-update-check`. The CLI updates itself on start by default\n\n### T3 Code\n\n1. Set T3CODE_TELEMETRY_ENABLED=false before starting the server if you don't want usage events sent\n2. Install and log in to at least one provider CLI first, such as codex login or claude auth login\n3. Use a managed policy to fix settings across a team\n\n## Questions\n\n### Which is better for AI agents, Junie CLI or T3 Code?\n\nT3 Code scores 51.9 (D) on agent readiness against Junie CLI's 49 (D), and leads in 4 of 7 scored categories. Junie CLI leads on schema \u0026 documentation, security \u0026 auth and transparency \u0026 trust.\n\n### Are Junie CLI and T3 Code open source?\n\nNo open-source release is listed for Junie CLI. T3 Code is open source (MIT).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/junie-vs-t3-code.json, and with the fewest tokens: https://www.anchorterminal.com/compare/junie-vs-t3-code.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"junie\", \"b\": \"t3-code\"}`.
