What Cline does
Cline is an open-source (Apache-2.0) autonomous coding agent that works inside VS Code, JetBrains (early access), the terminal, or embedded via SDK, handling multi-file edits and executing shell commands with a plan-then-act, human-approval workflow. It is free itself; users pay only for the underlying LLM inference, either via their own API keys or Cline's optional ClinePass credit subscription.
What you get: Plan-then-act agent workflow, Human-approval gating, MCP Marketplace, Multi-root workspaces, SDK embedding.
Typical jobs: BYOK agentic coding in VS Code; Budget-conscious autonomous agent use; Embedding an agent via SDK.
Worth knowing: EXCLUDED CANDIDATE: Continue (from the original candidate list) was replaced by Cline. Continue's own GitHub README states 'The continuedev/continue repository is no longer actively maintained and is read-only for all users' following its acquisition by Cursor; its last release was a final 2.0.0 with no further development. Cline is substituted as a live, actively maintained open-source alternative in the same category.
What users complain about: ClinePass page markets 'generous quotas' and a relative multiplier but does not publish an absolute monthly usage cap (Cline pricing page (official, doc-based))
Pricing and plan limits
Verified August 2026| Plan | Monthly | Annual (per mo) | Limits |
|---|---|---|---|
| Open Source | Free | n/a | Free extension/CLI/SDK; pay only for AI inference on a usage basis via your own API keys, no subscription required |
| ClinePass | $9.99 | n/a | First month promotional rate $4.99, then $9.99/month; described as 'generous quotas' and '2-5x the usage compared to standard API rate limits', exact request/token cap not published; additional processing fees may apply |
| Enterprise | not disclosed | n/a | Custom pricing |
Where it wins
- 66k+ GitHub stars and an active Apache-2.0 open-source project with a real plugin ecosystem (MCP Marketplace) rather than a closed black box
- No forced subscription -- BYOK usage is genuinely free beyond raw model inference cost, and works across VS Code, Cursor, and Windsurf as host editors
Where it falls short
- Cost-transparency is inherently variable since inference billing depends entirely on which model/provider you choose -- there is no flat, predictable monthly price unless you take ClinePass
- ClinePass itself doesn't publish a numeric monthly request/token quota, only the qualitative claim of '2-5x the usage compared to standard API rate limits'
