Pricing
FreeGemini CLI had a genuinely free tier from June 2025 to June 18, 2026: 60 model requests per minute and 1,000 requests per day via a personal Google account, providing access to Gemini 2.5 Pro and its 1M token context window at no cost. This made it the most generous free terminal coding agent in the market during that period. Starting March 2026, Google restricted free-tier users to Flash models and prioritized enterprise traffic. On June 18, 2026, Google discontinued free, Google AI Pro, and Google AI Ultra access entirely. Existing enterprise customers with paid Gemini Code Assist Standard ($19/user/month annual) or Enterprise ($45/user/month annual) licenses retain full Gemini CLI access with model updates and security patches. The Apache 2.0 source code remains publicly available. Individual users seeking free access are directed to Antigravity CLI (Google's closed-source Go-based replacement) or can self-host a fork with their own LLM API keys.
FreeCline itself is free and open source — there are no seat fees or subscriptions for the core agent. You pay AI inference costs directly to your chosen LLM provider (Anthropic, OpenAI, Google, etc.) with a full per-request cost breakdown shown in the UI. Cline shows every token used and every dollar spent transparently. ClinePass ($9.99/month) is an optional managed billing subscription that provides 2–5x more usage on popular open coding models compared to standard API rates, with one-click sign-in and no need to manage API keys yourself. It is not required — BYOK (bring your own key) is always available at zero markup. Enterprise pricing is custom and adds JetBrains extension, SSO/OIDC/SCIM, SLA, centralized billing, RBAC, team management dashboard, authentication logs, limit inference providers, dedicated support, VPC deployments, OpenTelemetry, and advanced config management.

Gemini CLI

Gemini CLI Pros & Cons

Pros

  • 105,000+ GitHub stars in ~1 year — one of the fastest-growing open source developer tools in history
  • Apache 2.0 license with source donated to Linux Foundation — maximum openness and community auditability
  • Google Search grounding enables live documentation retrieval during execution — unique capability no other terminal agent has built-in
  • 1M token context window with Gemini 3 — understands entire large codebases without chunking
  • Daily nightly builds and weekly stable releases — most actively maintained open-source terminal agent
  • Free for Gemini Code Assist Standard/Enterprise licensees — no additional per-seat cost for enterprise teams already on GCP

Cons

  • Free consumer tier discontinued June 18, 2026 — individual users must migrate to Antigravity CLI or self-host a fork
  • 28-day migration notice for shutting down a tool with 100K+ stars and 6K+ community contributors was widely criticized as too short
  • Antigravity CLI replacement is closed-source — the open-source spirit of the original project was lost in the transition
  • Self-hosting a working fork requires an independent LLM endpoint — non-trivial for most developers
  • Gemini 3 model available in Preview only on enterprise tier — free tier was restricted to Flash models from March 2026 onward
  • Enterprise-only access from June 2026 limits the product's relevance for individual developers
Cline

Cline Pros & Cons

Pros

  • Completely free and open source (Apache 2.0) — no seat fees, no subscriptions, no proprietary lock-in ever
  • 67K+ GitHub stars and 8M+ developers — largest open-source coding agent community by any measure
  • Full cost transparency at zero markup — the only major coding agent that shows exactly what you pay per request with no hidden pricing
  • Model-agnostic with 12+ provider integrations — switch any time without changing workflow or losing your setup
  • Plan/Act mode gives full human-in-the-loop control — approve every action or flip to autopilot when confidence is high
  • Trusted by engineers at Salesforce, Oracle, Amazon, Microsoft, eBay, Visa, IBM, and LG

Cons

  • BYOK means you manage your own LLM API keys and billing — can be confusing for non-technical users used to flat subscriptions
  • No built-in inline autocomplete (Tab completions) — Cline is an agent, not a code-completion tool like Copilot or Tabnine
  • JetBrains support is still Early Access — not as polished as the VS Code extension
  • Some engineers joining OpenAI's Codex team in January 2026 raised community concerns about long-term momentum (Cline confirmed no acquisition and remains independent)
  • Enterprise features (SSO, RBAC, JetBrains, SLA) require a custom sales contract — no self-serve team plan available
