AI coding agents, ranked

15 reviewed agents compared

Standalone tools you can write code with today — terminal CLIs, IDE extensions, desktop apps — not plugins or config packs. The order is not popularity: it is one FARS review across trust, reliability, adaptability, convention, effectiveness and verifiability, and every score links to its evidence.

How this ranking is built

What qualifies: standalone, maintained tools of this kind that people search for by name. Plugins, skill packs and config layers built on top of them are left out and listed on the host tool's profile. The membership list is kept in our public repository, so every change is on record.

The order is the FARS total; stars only break ties, because popularity measures attention rather than whether something holds up. Two limits are worth knowing before you read the order. These are static reviews — source, documentation and repository metadata, with no runtime reproduction — which caps reliability, effectiveness and verifiability and puts the achievable maximum at 77 rather than 100. And a gap of a few points sits inside the noise of that method. Read the table as a shortlist worth investigating, not as a verdict; every score links to its full dimension breakdown and the evidence behind it. Review method →

2. Kilo Code — The Open-Source All-in-One Coding Agent

Where it differs

The source does not mention specific competitors.

3. Gemini CLI

4. Cline

Where it differs

Cline is not tied to one model provider: the material lists Anthropic, OpenAI, Google, OpenRouter, Vercel AI Gateway, AWS Bedrock, Azure/GCP Vertex, Cerebras, Groq, Ollama, LM Studio, and any OpenAI-compatible API. The documented differentiation is therefore the connected model or gateway rather than a change in Cline's CLI, editor, or SDK delivery modes.

5. Oh My Pi

Where it differs

Oh My Pi is a fork of Mario Zechner's Pi (pi-mono). The repository describes it as extending Pi with a coding-focused surface for sessions, subagents, slash commands, extensions, native tools, and multi-provider workflows.

6. Qwen Code

Where it differs

Qwen Code names Claude Code as a comparison point and states corresponding support for SubAgents, Agent Teams, MCP, Plan Mode, LSP integration, sandboxing, Git worktrees, IDE plugins, SDKs, headless mode, and session management. Its listed differentiators are open-source models and framework, multi-protocol provider support, Agent Arena, the qwen serve shared-agent service, and Telegram, DingTalk, WeChat, and Feishu channels.

8. goose

Where it differs

Compared to coding-focused terminal agents like Codex CLI or opencode, goose's key differentiator is generality — it isn't limited to code tasks, and natively supports reusing a Claude/ChatGPT/Gemini subscription instead of forcing a separate API. If you need a local agent that spans more than just coding, or want to build an internally distributed variant on the same base, goose fits better.

9. opencode

Where it differs

Compared to similar terminal coding agents like Codex CLI or Claude Code, opencode's main differentiator is being fully open source (MIT) without tying you to a single model vendor's subscription, plus much broader install channel support. It suits teams who want to self-host, audit the code, or avoid being locked into one AI vendor's account system.

10. Open Interpreter

Where it differs

Compared with OpenAI Codex, this repository identifies itself as a Codex fork focused on emulating high-performing agent harnesses for low-cost models while retaining Codex exec protocol compatibility. The original Python Open Interpreter project continues as the community-maintained endolith/open-interpreter fork; this repository is the newer Rust version.

13. Pi Agent Harness

Where it differs

The README does not explicitly mention other agents, but as a multi-provider LLM API and agent toolkit, it can be compared to LangChain, Claude Code, or OpenAI Codex. However, Pi emphasizes self-extensibility and a TUI, and is MIT-licensed.

14. OpenClaude — Universal Terminal AI Coding Agent

Where it differs

Compared to Claude Code, OpenClaude is designed for multi-provider support, whereas Claude Code is primarily for Anthropic models.

Where it differs

The repository does not explicitly mention other AI coding agents, so no comparison is provided.

In scope, not ranked yet

These projects belong in this ranking, but their FARS review could not find enough public source evidence to score (for example, the repository ships no source, or its docs moved off-repo). A 0 would be a verdict FollowAgents never reached, so they are listed here instead of ranked.
