Curated quotes from Hacker News, Reddit, Product Hunt, and review blogs. Dates shown so you can judge whether early criticism still applies.
“It's like having a senior dev who actually reads and understands your entire codebase before making suggestions.”
“Cline is the OG with 5 million installs — still the best open-source autonomous agent in VS Code.”
“Step-by-step permission gating is the right safety model — but on long tasks the constant prompting slows you down vs more autonomous agents.”
“Kilo Code and Roo Code (both Cline forks) ship features faster — Cline still wins on stability and ecosystem.”
“Brilliant coding assistant — works great for both VS Code and JetBrains IDEs with access to many providers.”
“The model switching UI is the clearest advantage over Cline — swapping models takes two clicks.”
“On VS Code, this is the best AI coding extension by far — it blends Cline and Roo Code with better UX and reliability.”
“Sometimes stuck in loops — not sure if it's the LLM or the prompt's problem.”
“My biggest complaint is no ability to use it within Zed.”
Key criteria to evaluate when comparing Coding Agents solutions:
Cline is the most-installed open-source autonomous coding agent on the VS Code marketplace, with 5M+ installs. As a VS Code extension it can autonomously create and edit files, run terminal commands, use the browser, and handle complex multi-step engineering tasks — always asking for permission at each step rather than running silently.
Cline pioneered the agentic coding pattern that Kilo Code and Roo Code later forked. It supports the Model Context Protocol (MCP) so the agent can extend its own toolset, and it works with any LLM provider — Anthropic Claude, OpenAI, Google, and local models. Pairing Cline with Claude Sonnet's tool-use capabilities produces some of the most capable open-source agent workflows available.
The OSS extension is completely free for individuals — you only pay for AI inference on a usage basis with no markup or vendor lock-in. The Cline Teams plan is free through Q1 2026, then $20/user/month with the first 10 seats always free, adding JetBrains support, centralized billing, and team admin features.
Kilo Code is an open-source AI coding agent that runs as an extension in VS Code, JetBrains IDEs, and as a standalone CLI. It was forked from Cline and Roo Code in 2024 and now serves 1.5M+ developers, ranking as the most-used open-source coding agent extension.
Kilo's standout feature is Orchestrator mode, which decomposes complex tasks into subtasks and routes them to specialist sub-agents — Architect for planning, Coder for implementation, and Debugger for testing and fixes. It also provides inline autocomplete, browser automation, automated refactoring, and connects to 500+ models across 60+ providers (Anthropic, OpenAI, Google, Mistral, local Ollama, OpenRouter).
Pricing is BYO API key with zero markup — Kilo charges the exact list price of Anthropic, OpenAI, and Google. Optional Kilo Pass credit subscriptions start at $19/mo, with Teams at $15/user/mo. Co-founded by GitLab co-founder Sid Sijbrandij; raised $8M in seed funding (December 2025) led by Cota Capital with participation from General Catalyst, Breakers, Quiet Capital, and Tokyo Black.
AI-powered developer tools that can write, review, debug, and refactor code—ranging from IDE copilots to fully autonomous software engineering agents.
