# Best AI Coding Assistants in 2026 Source: https://listme.name/best/ai-coding-assistants AI coding assistants now come as editors, terminal agents and agents inside GitHub. This ranking weighs what each one does on real repositories, how it handles cost and model choice, and whether its source is open for inspection. ## 1. Claude Code (score 93.0) Agentic coding from the terminal, IDE, Slack or the web, included in Pro and Max. It has no free tier, and heavier daily use points to the Max plan. - Best for: Terminal-first agentic coding inside a Claude plan - Subscription | Command line, Web - Website: https://claude.com/product/claude-code - Page: https://listme.name/software/claude-code ## 2. Cursor (score 92.0) An AI-first editor with agents, cloud agents and team controls, and a free Hobby plan with limits. It is an editor you switch to, so teams that want to keep their current editor may prefer an extension. - Best for: Developers who want an AI-first editor - Free plan, paid upgrades | macOS, Windows, Linux - Website: https://cursor.com/ - Page: https://listme.name/software/cursor ## 3. GitHub Copilot (score 91.5) Works in VS Code, the Copilot CLI and GitHub.com, and can take an issue to a pull request. Usage is metered in AI credits, and it fits best where code already lives on GitHub. - Best for: Teams already hosting code on GitHub - Free plan, paid upgrades | Web, Windows, macOS, Linux, Command line - Website: https://github.com/features/copilot - Page: https://listme.name/software/github-copilot ## 4. OpenCode (score 87.5) MIT-licensed agent that runs in a terminal, an IDE or a desktop app, with free models included and any provider's models connectable. Its public repository and session features place it near Cline in this list. - Best for: Open-source terminal agent with any model provider - Free and open source | Windows, macOS, Linux, Command line | open source (MIT) - Website: https://opencode.ai/ - Page: https://listme.name/software/opencode ## 5. Cline (score 86.5) An Apache 2.0 agent for desktop, IDE, terminal and SDK, with Plan and Act modes and MCP support. Cost depends on the model provider, and its ability to run commands needs careful permission settings. - Best for: Open-source agent that works with any model - Free and open source | Windows, macOS, Linux, Command line | open source (Apache-2.0) - Website: https://cline.bot/ - Page: https://listme.name/software/cline ## 6. Kilo (score 85.0) MIT-licensed agent with VS Code and JetBrains extensions, a command-line tool and cloud agents, using 500 or more models at provider prices. Its paid cloud and enterprise tiers are separate from the open-source agent. - Best for: Open-source agent across IDE, terminal and cloud - Free and open source | Windows, macOS, Linux, Command line | open source (MIT) - Website: https://kilo.ai/ - Page: https://listme.name/software/kilo ## 7. Aider (score 83.5) A terminal tool that commits each AI edit to git and runs lint and test loops after changes. It has no graphical editor, which suits developers who already work in the terminal. - Best for: Terminal pair programming with git history - Free and open source | Command line | open source (Apache-2.0) - Website: https://aider.chat/ - Page: https://listme.name/software/aider ## 8. OpenAI Codex (score 81.0) An Apache 2.0 terminal agent from OpenAI that runs on the user's computer. The pages checked tie model access to OpenAI sign-in, and it offers no graphical interface. - Best for: Open-source terminal agent in the OpenAI ecosystem - Free and open source | Command line | open source (Apache-2.0) - Website: https://github.com/openai/codex - Page: https://listme.name/software/openai-codex ## 9. Kiro (score 80.5) AWS-built agentic IDE and CLI that turns prompts into specs and runs parallel agents. The Free plan includes 50 credits, and usage is metered in credits that vary by model, so cost is harder to predict than a flat plan. - Best for: Spec-driven work inside the AWS ecosystem - Free plan, paid upgrades | macOS, Windows, Linux, Command line - Website: https://kiro.dev/ - Page: https://listme.name/software/kiro ## 10. Zed (score 79.5) A fast multiplayer code editor with a free Personal plan and AI through Pro or your own keys. AI is an add-on to the editor, so it ranks below the dedicated coding agents here. - Best for: Fast editor with optional AI and real-time collaboration - Free plan, paid upgrades | macOS, Linux, Windows | open source (GPL-3.0) - Website: https://zed.dev/ - Page: https://listme.name/software/zed ## How to choose - **Where you work:** Editors suit people who want AI inside the screen they already use; terminal agents suit scripted, remote or server work. - **Cost and limits:** Compare free-tier limits and usage metering, since Claude Code, GitHub Copilot and Cursor each meter usage differently. - **Open source:** Aider, Cline, OpenAI Codex and Zed publish their source, which helps when you need to audit what an agent does. - **Model choice:** Cline and Aider accept models from several providers, while the commercial tools here use the models their vendors offer. ## Criteria - Agent capability on real code - Cost and usage limits - Model and provider choice - Source openness and licensing - Fit with editor or terminal ## FAQ **What is the best free AI coding assistant?** Aider and Cline are open source and free to install, so their cost is the model provider you connect. Cursor's Hobby plan and GitHub Copilot's Free plan are free to start with usage limits. **Is Claude Code free?** Claude Code is included in the paid Pro and Max plans. The product page lists no separate free tier for it. **Which coding assistants are open source?** Aider, Cline and OpenAI Codex publish their code under Apache 2.0. Zed publishes its editor under GPL-3.0, with Apache 2.0 components. OpenCode and Kilo publish their code under MIT. **Which coding tools run in the terminal?** Claude Code, Aider and OpenAI Codex are terminal-first. Cline also has a command-line tool, and GitHub Copilot includes the Copilot CLI.
