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 Paseo +40

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.

Paseo 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.

Schema & documentation Gemini CLI +28

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).

Paseo 65

Harness reading. Public docs, a CLI and plugin examples in the repository (65).

Transparency & trust Gemini CLI +22

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.

Paseo 68

Apache 2.0 for everything but third-party components (30). No telemetry and agents run on your machine (22 of 30). CHANGELOG.md, no deprecation policy (10). States no telemetry (20). 30 + 22 + 10 + 20 = 82.

Reliability Gemini CLI +21

Gemini CLI 71

Local-package reading. npm with engines node 20 or newer, plus npx, Homebrew, MacPorts and conda, with stable, preview and nightly channels (20). Public CI with ci.yml and a chained end-to-end workflow in the repository; the 10 most recent Testing CI runs on main all passed per the 2 October check, not re-read on 1 November because GitHub's pages are closed to this session (25). 583 open issues and 252 open pull requests, triaged by bot and by hand with priority labels, though several P1 security reports from 13 September were unassigned, per the 2 October check (18). releases.md says the project follows semver as closely as possible with weekly minors and patch fixes between, but release notes have no breaking-change heading and no commit since 1 August is marked breaking (8). 0.66.0, pre-1.0 (0). 20 + 25 + 18 + 8 + 0 = 71.

Paseo 50

Local software. Desktop builds, an Android APK, a Docker image and a Nix package (20). ci.yml 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). CHANGELOG.md (15). Version 0.15.3 (0). 20 + 15 + 0 + 15 + 0 = 50.

Maintenance & community Gemini CLI +13

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.

Paseo 75

v0.15.3 and commits on 7 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 builds (15). CI on push (10). 30 + 20 + 0 + 15 + 10 = 75.

Security & auth Gemini CLI +9

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.

Paseo 58

Harness reading. The README says no telemetry, tracking or forced log-ins (30 of 30). Worktree per agent, on your own machine (10 of 20). No prompt-injection guidance (5). No audit log (5). SECURITY.md (8). 30 + 10 + 5 + 5 + 8 = 58.

How the scores have moved

Verdicts

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.

Paseo

A self-hosted, open-source workspace for running many coding agents on your own machines, scriptable from the CLI and reachable from phone, web or desktop, with no telemetry or forced log-in. It's pre-1.0 and run largely by one maintainer.

Before you call either

Gemini CLI

  1. Set GEMINI_TRUST_WORKSPACE to true only for trusted inputs in CI. Since 0.39.1 headless mode doesn't trust a folder on its own
  2. Turn on the sandbox with -s or tools.sandbox, and pick a proxied Seatbelt profile on macOS to cut network
  3. Set privacy.usageStatisticsEnabled to false to stop usage statistics
  4. Since 0.63.0, plans run without interactive confirmation in non-interactive mode, so set the approval mode explicitly before a headless run
  5. Authenticate with a paid Gemini API key or Vertex credentials. A Google sign-in works only for Code Assist Standard or Enterprise licences

Paseo

  1. Run the daemon on the machine that has your tools and credentials, and connect from the clients
  2. Script runs from the CLI for repeatable agent jobs

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
