What our tests found

Cline

3/3 headless CLI runs fixed our seeded cart bug (4/4 tests pass) in 24-35s with a free OpenRouter model, without editing the test file.CLI, free model

Pros
  • Headless CLI with a -y mode ran start to finish with no prompts
  • Fixed the seeded bug in 3 of 3 runs and never touched the test file
  • Works with free OpenRouter models, so our test cost $0
Cons
  • Slower than Aider on the same model (24-35s vs 9-13s)
  • Warns on Node versions below 22.15
  • The -k flag saves your API key into the config directory

Who it’s for: Developers who like Cline in VS Code and want the same agent in a terminal or CI, with any model.

Gemini CLI

Google-account login for individuals no longer works (the CLI says to migrate to Antigravity), so we used a free-tier API key. Run 1 (16 Oct 2026) wrote a complete todo app in about 5 minutes, then hit the free tier's 20-requests-per-day limit for gemini-3.8-flash. We re-ran on 17 Oct 2026: runs 2 and 3 both failed immediately with the same 429 quota error and wrote no files. We verified the run-1 app ourselves in headless Chrome: add, complete, delete, filters, reload persistence and the mobile layout all passed.CLI, free API tier

Pros
  • The one app it finished passed every check in our own headless browser test, including mobile
  • Single command, headless mode with JSON output
  • Free API key tier, no card
Cons
  • Google-account login for individuals fails with 'client no longer supported ... migrate to Antigravity'
  • Free tier allowed only 20 requests per day on gemini-3.8-flash; one small app used them all
  • Re-test on 17 Oct 2026: runs 2 and 3 both exited 173 with quota exhausted before writing any files
  • The saved Google-login setting overrides GEMINI_API_KEY until you change settings

Who it’s for: Developers with a paid Gemini API key or Vertex AI who want an open-source terminal agent; casual free use is now very limited.

Verdict

Scores use rubric v0.1 from separate runs. Editions and tasks can differ (see Edition tested and What our tests found); some tests were a single run, which caps reliability scores. Overall: Cline 9.2, Gemini CLI 6.1. Check the free-tier limits above against your project before choosing.
