Which agent can write and run code for me from the terminal or a ticket?

Claude Code leads with an evidence score of 80/100, ahead of Cursor (70) and GitHub Copilot (58). 16 of 19 can be used free, 9 are open source. Best for developers comfortable delegating whole tasks from the terminal: Claude Code.

Ranked by evidence — GitHub stars, Hacker News mentions, release activity and how much you can use for free. Recomputed nightly. How the score works.

1
Terminal-based agentic coding tool that reads, edits, tests, and commits in your repo.

+ Handles long multi-step tasks across a whole repo with strong tool use and MCP support.
− Token spend on the API plan can be high and Pro-plan rate limits reset only every five hours.

Cursor Free tier
A VS Code fork with built-in AI autocomplete, chat, and an agent mode that edits across your codebase.

+ Tab autocomplete predicts multi-line edits across files better than any competitor.
− Usage-based pricing changes and request limits on Pro have repeatedly frustrated heavy users.

GitHub Copilot Free tier
AI pair programmer in your IDE and on GitHub, with completions, chat, code review, and a cloud coding agent.

+ Deepest GitHub integration: assign an issue to Copilot and it opens a PR.
− Completions and agent lag behind Cursor and Claude Code in quality despite more models being offered.

OpenAI Codex Free tier
OpenAI's coding agent, available as an open-source CLI, an IDE extension, and a cloud sandbox in ChatGPT.

+ Cloud mode runs many tasks in parallel sandboxes and opens PRs for each.
− Native Windows support in the CLI arrived late and sandboxing can block legitimate commands.

Goose Open source
Open-source, extensible local AI agent that automates engineering tasks via MCP extensions.

+ MCP-first design means any MCP server becomes a Goose capability with no glue code.
− Less tuned for coding than Claude Code, so results vary widely by model.

Gemini CLI Open source
Open-source terminal agent that brings Gemini into your shell for coding and automation tasks.

+ Free tier gives a 1M-token context window and around 1,000 requests per day.
− Less reliable at multi-step edits than Claude Code and quietly falls back to Flash under load.

Devin Paid
Cloud-hosted autonomous software engineer that takes tickets and ships pull requests.

+ Runs fully unattended in its own VM with browser, shell, and editor, and reports back on Slack.
− Struggles with ambiguous tasks and the price per compute unit adds up on long sessions.

Claude Agent SDK Open source
SDK exposing the Claude Code agent loop, tools, and MCP support for building custom agents in Python or TypeScript.

+ Inherits Claude Code's file, shell, and subagent tooling, so agents are production-grade on day one.
− Tied to Claude models and the Claude Code runtime rather than a provider-agnostic design.

Cline Open source
Open-source autonomous coding agent for VS Code with plan/act modes and MCP support.

+ Plan mode lets you approve an approach before the agent touches files or runs commands.
− Reading whole files into context burns API tokens fast on big projects.

Aider Open source
Open-source terminal pair programmer that edits files and auto-commits with any LLM.

+ Repo map and git-native workflow make it cheap and precise with any model, including local ones.
− It is a chat-driven editor rather than an autonomous agent, so you steer every step.

Kilo Code Open source
Open-source VS Code agent merging Cline and Roo Code features with built-in model access.

+ Works out of the box with a built-in provider so no API key setup is needed.
− Less mature than the projects it forked and still catching up on polish.

OpenHands Open source
Open-source platform for autonomous coding agents, formerly OpenDevin, with a hosted cloud option.

+ Top-ranked open agent on SWE-bench that you can run on your own infrastructure.
− Docker-based local setup is heavy and the UI is rougher than commercial agents.

Roo Code Open source
Cline fork with custom modes, boomerang subtasks, and more configurable agent behaviour.

+ Custom modes (Architect, Code, Debug) and Orchestrator subtasks keep context small per step.
− Rapid releases mean frequent regressions and settings sprawl.

Amp Free tier
Agentic coding tool from Sourcegraph that runs in VS Code and the CLI with shared threads.

+ Threads are shareable, so a team can inspect exactly how an agent produced a change.
− No model picker; Amp chooses the model and spends your credits accordingly.

AI chat, completions, and the Junie coding agent built into IntelliJ, PyCharm, and other JetBrains IDEs.

+ Uses the IDE's own semantic index and refactorings, so edits respect project structure.
− Quota-based AI credits run out quickly on the lower tiers.

Windsurf Free tier
AI-native code editor whose Cascade agent tracks your actions and makes multi-file changes.

+ Cascade keeps context of what you just did in the editor and terminal without being told.
− Ownership turmoil in 2025 (OpenAI deal collapse, Google, then Cognition) caused model-access gaps.

AI coding assistant and agent built around a context engine for very large codebases.

+ Context retrieval holds up on monorepos with hundreds of thousands of files.
− Pricing moved to credits and sits well above Copilot for individual developers.

Kiro Free tier
AWS's agentic IDE that turns prompts into specs, then implements them with hooks and steering files.

+ Spec-driven workflow produces requirements and design docs before code, which keeps agents on track.
− Waitlists and tight free-tier limits made it hard to actually use after launch.

Jules Free tier
Asynchronous coding agent that clones your GitHub repo into a cloud VM and opens PRs.

+ Runs in the background and sends an audio changelog summarising each PR.
− Limited daily task quota and no way to intervene mid-task once it starts.
