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.
Payments & pricing Emdash +40
Emdash 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.
Gemini CLI 20
Harness reading of the published rubric. No payment protocol (0). Token prices and plan prices are public without a login (20). The 1,000 requests a day Google sign-in tier ended on 18 June 2026. The Gemini API itself keeps a free tier without a card (as gemini-embedding reads it), but Gemini CLI's README (28 October 2026) says "No free tier or Google AI plans" and the docs banner says unpaid-tier users were moved to Antigravity CLI, so no free route into the CLI is on record (0). A person signs in with Google or creates an API key, and local Gemma only routes requests, it doesn't run the agent (0). 0 + 20 + 0 + 0 = 20.
Schema & documentation Gemini CLI +38
Emdash 55
Harness reading. Docs site and a workspace server package (55).
Gemini CLI 93
Framework reading. settings.schema.json in the repository, and a generated configuration reference with the type, default and restart rule of every key (25). llms.txt at geminicli.com serving the documentation as Markdown (10). Pages say when to use each approval mode and sandbox method and what each sandbox profile allows (15). Approval modes, sandbox commands and Seatbelt profiles are enums (13). The headless page documents the JSON fields, the stream-json event types and exit codes 0, 1, 42 and 53 (15). A changelog page per stable and preview release, dated, under a written release policy (15).
Transparency & trust Gemini CLI +36
Emdash 54
Apache 2.0 (30). A telemetry page on the docs site (not read) (18 of 30). No deprecation policy (5). Disclosed with an opt-out (15 of 20). 30 + 18 + 5 + 15 = 68.
Gemini CLI 90
Apache-2.0 (30). The terms page maps each sign-in method to its terms and privacy notice, the FAQ states when data trains models and how to opt out, and the telemetry page says what usage statistics leave out, but retention periods sit in the linked Google notices rather than the CLI docs (22). Dated deprecation notices exist. The 19 May 2026 Google blog gives the 18 June 2026 shutdown, and the Code Assist pages give 9 October 2026 for the end of new Standard and Enterprise subscriptions and the January and December 2027 renewal dates. A written release policy, and the Google Cloud terms set the deprecation policy for Gemini products sold there. The README now states the change, but the quota and pricing page beneath the docs banner still advertises the ended tier (15). Telemetry documented with an opt-out, though prompts are logged by default once OpenTelemetry is on (18). 30 + 22 + 15 + 18 = 85.
Security & auth Gemini CLI +29
Emdash 38
Harness reading. Telemetry is described as optional and disabled in Settings or with TELEMETRY_ENABLED=false, which reads as on by default (15 of 30). Worktree per task and remote machines over SSH (10 of 20). No prompt-injection guidance (5). No audit log (5). No security policy file found (3). 15 + 10 + 5 + 5 + 3 = 38.
Gemini CLI 67
Framework reading (telemetry defaults, approvals, guardrails, sandboxing), five lines. Usage statistics on by default (privacy.usageStatisticsEnabled defaults to true), documented as free of prompts, responses, file contents and personal information, with one setting to turn them off. Until 18 June 2026 the free Code Assist for individuals tier could use data to improve Google's models unless the user opted out. Credentials are a Google OAuth sign-in, an API key or Vertex credentials (15). Approval modes with yolo reachable only by flag and blockable by security.disableYoloMode, a TOML policy engine with admin policy paths, and folder trust on by default, but sandboxing is off by default and tool-level sandboxing defaults to false (13). Environment-variable redaction, and 0.61.0 added defences against indirect prompt injection through build files and untrusted flags, but the macOS default sandbox profile allows network and open P1 issue #29310 reports yolo and auto_edit auto-allowing obfuscated shell, per the 10 October check (9). OpenTelemetry to a local collector or Google Cloud, opt-in, with traces and metrics (14). SECURITY.md routes reports to g.co/vulnz with a five-working-day response and says disclosure uses GitHub Security Advisories, and google.com has a valid security.txt to 2030. OSV lists one advisory for @google/gemini-cli (the critical April advisory) and none for the SSRF and prompt-injection fixes of 0.59.0 and 0.61.0 (16). SOC 2 isn't scored on the framework reading. 15 + 13 + 9 + 14 + 16 = 67.
Agent ergonomics Gemini CLI +23
Emdash 55
Harness reading. Issue intake from Linear, GitHub, Jira and others, diff review, pull requests and CI checks in one place, local or over SSH (55).
Gemini CLI 78
Framework reading, adapted to a harness driven by a pipeline. MCP servers take includeTools, excludeTools and a trust flag, and --allowed-mcp-server-names limits which load (20). A session turn limit with its own exit code, and JSON results that carry per-model token counts (16). Documented exit codes and an error object in JSON output (18). --resume and checkpointing (14). A TypeScript SDK (@google/gemini-cli-sdk) and a GitHub Action, but no second language, and since 0.39.1 a CI run has to set GEMINI_TRUST_WORKSPACE to work in its own checkout (10).
Maintenance & community Gemini CLI +18
Emdash 70
v1.2.11 on 6 November 2026 (30). v1.2.9, v1.2.10 and v1.2.11 within two weeks (20). GitHub issues and pull requests weren't read (GitHub's pages refuse these sessions), so that line is scored absent (0). Current installers and Homebrew cask (15). Release workflows, no test CI (5). 30 + 20 + 0 + 15 + 5 = 70.
Gemini CLI 88
0.66.0 on 2026-10-27 (30). 14 stable releases from 3 August to 1 November (0.54.0, 0.54.4, 0.55.1 and 0.56.0 to 0.66.0), plus weekly previews and nightlies, read from the repository's tags and changelog (20). 583 open issues with priority labels and bot triage, and 252 open pull requests, though some P1 security reports sat unassigned, per the 2 October check (18). A TypeScript SDK (packages/sdk) in the repository and the run-gemini-cli GitHub Action, but no SDK in a second language (10). CI, nightly evals and an Allstar policy (10). 30 + 20 + 18 + 10 + 10 = 88.

How the scores have moved
Verdicts
Emdash
A mature open-source app for parallel coding agents in Git worktrees, with issue intake from a dozen trackers and remote machines over SSH. Telemetry is on unless you turn it off, and no test workflow was found in the repository.
Gemini CLI
Apache-2.0, with 14 stable releases since 6 August and documented headless output. Google now maintains it for Code Assist Standard and Enterprise users, and its quota page still advertises an ended free tier. Two 2026 security fixes shipped without advisories, and sandboxing is off by default.
Before you call either
Emdash
- Launch with TELEMETRY_ENABLED=false if you don't want telemetry
- Use the SSH mode to keep agents on a remote machine
Gemini CLI
- Set
GEMINI_TRUST_WORKSPACEto true only for trusted inputs in CI. Since 0.39.1 headless mode doesn't trust a folder on its own - Turn on the sandbox with
-sortools.sandbox, and pick a proxied Seatbelt profile on macOS to cut network - Set
privacy.usageStatisticsEnabledto false to stop usage statistics - Since 0.63.0, plans run without interactive confirmation in non-interactive mode, so set the approval mode explicitly before a headless run
- Authenticate with a paid Gemini API key or Vertex credentials. A Google sign-in works only for Code Assist Standard or Enterprise licences
