AI Coding Agents and Assistants: Choose Your Workflow
48 tools · listed in dataset order, no ranking · 1 discontinued, listed last
AI coding tools are not interchangeable. This category covers AI code editors (Cursor, Devin Desktop, Kiro, Google Antigravity), assistants and agents inside the IDE you already use (GitHub Copilot, Cline, Junie, Kilo Code), terminal agents (Claude Code, OpenCode, OpenAI Codex, Qwen Code), cloud agents that work on their own machines and return pull requests (Devin, Amp, Capy, Replicas), and tools that run several agents side by side (Orca, T3 Code, JetBrains Air, OpenHands). It also lists app builders (Replit, Lovable), code review and testing agents (Open Code Review, Momentic Mo, ARTEMIS), operations agents for incidents and cloud reviews (AWS DevOps Agent, Polylane), and a docs agent that opens pull requests when code changes (Mintlify Autopilot). Start with where you want the work to happen and who pays for the model, then compare tools of that kind.

How to choose a coding tool
Workflow fit beats raw model capability
The strongest model in the wrong interface costs productivity. AI code editors (Cursor, Devin Desktop, formerly Windsurf, Kiro, Google Antigravity) replace your editor. IDE assistants and extensions (GitHub Copilot, Cline, Junie, Kilo Code) add completions, chat, and agents to VS Code or JetBrains. Terminal agents (Claude Code, OpenCode, OpenAI Codex, Qwen Code, Pi) take a task, edit files, and run commands from your shell. Cloud agents (Devin, Amp, Capy, Replicas, Cursor Cloud Agents, Copilot's cloud agent) take a ticket and come back with a branch or pull request to review. Many tools now span several of these, so check which surface you would actually use.
Local or cloud: where the agent runs
Local agents such as Claude Code, Codex CLI, OpenCode, Cline, and goose work in your checkout with your tools and test setup, and stop when your machine does. Cloud agents run in isolated machines: Cursor Cloud Agents clone your repo into cloud VMs, Codex cloud tasks keep working while your computer is asleep, Amp runs each thread on a remote machine it calls an orb, and Replicas and Capy run agents in cloud VMs connected to your repositories. Cloud runs need repository access and secrets set up for that environment. Orchestration tools (Orca, OpenRig, T3 Code, JetBrains Air) run several agents at once, and Orca and T3 Code give each one its own git worktree.
Separate the software price from the model bill
Open-source agents such as OpenCode, Cline, Kilo Code, goose, Qwen Code, and Pi are free software, but you pay a model provider per token or sign in with a subscription you already have, so cost depends on the model and how long tasks run. Orca, OpenRig, and T3 Code supply no model at all and run the agents you already pay for. Subscription products bundle model usage with limits: GitHub Copilot plans include AI credits, Claude Code needs a paid Claude plan or API usage, Codex's CLI and cloud tasks start at ChatGPT Plus or work with an API key, and Muse Code plans run from $5 to $200 a month. Cloud features can sit on higher tiers: Cursor's cloud agents start on its $30 Premium plan.
Code review is not optional
No AI coding tool eliminates the need for human review. Generated code introduces bugs, security issues, and license problems at rates proportional to the complexity. Approval defaults differ too: the Cline extension asks before acting unless you turn on auto-approve, while OpenCode V2's Build agent and the Cline CLI run commands without asking by default; Claude Code offers permission modes from plan-only to automatic approval; Muse Code turns on approvals and sandboxing by default. Check the default before you point an agent at a real repository.
Not every tool here writes your code
Replit Agent and Lovable build and host full apps from prompts, for people who may not start in an IDE. Open Code Review posts line-level review comments from the terminal or CI. Momentic Mo explores web and mobile apps to find and reproduce bugs, and ARTEMIS drives Android devices for test automation. AWS DevOps Agent and Polylane investigate production incidents, and AWS Well-Architected Agent, in preview, reviews AWS accounts and infrastructure code. Mintlify Autopilot, in beta, reads merged code changes and opens pull requests that update docs hosted on Mintlify; it needs a Mintlify Pro or Enterprise plan and GitHub. These complement a coding agent rather than replace it.

Editorial framing, not a ranking. Listings on this page are unordered.
Common tradeoffs
Editor-native vs terminal-first
Editor-native tools (Cursor, Devin Desktop, Kiro) offer tight IDE integration and visual diffs; terminal-first agents (Claude Code, OpenCode, Codex CLI) give task-driven automation and broader tool flexibility.
Autocomplete speed vs multi-file reasoning
Inline completions (GitHub Copilot, Cursor) stay in your editing flow but only touch the code around your cursor. Multi-file agents (Cursor's agent, Copilot agent mode, Claude Code) take longer but handle bigger refactors.
Local vs cloud execution
Local agents use your machine, tools, and credentials and need you nearby. Cloud agents (Devin, Amp, Capy, Replicas, Codex cloud) keep working when you log off, but need repository access and secrets configured in their environment.
Bundled subscription vs bring your own model
Cursor, Copilot, Claude Code, and Codex bundle model usage into plans with limits. OpenCode, Cline, Kilo Code, and goose are free software with a separate model bill that grows with task length and model choice.
One agent vs several in parallel
A single agent is easier to supervise. Orchestrators (Orca, OpenRig, T3 Code, JetBrains Air) and cloud platforms run several at once, which multiplies both output and the amount of review you need to do.
Single file vs whole codebase context
Inline completions draw on the code around your cursor; agent modes (Cursor, GitHub Copilot, Claude Code) read and edit across the repository. Sourcegraph Cody, available only with Sourcegraph Enterprise, draws context from local and remote codebases through Sourcegraph search.
Common questions about coding tools
Which AI coding tool should I choose if I'm just starting out?
Start with where you already work. In VS Code or JetBrains, try GitHub Copilot's free tier (2,000 completions and 50 chat requests a month), or an open-source extension such as Cline with a model you choose. If you are willing to switch editors, Cursor has a free plan with limited agent requests. If you prefer the terminal, Claude Code comes with paid Claude plans and Codex's CLI with ChatGPT Plus and above. Compare Cursor and Copilot →
What is the difference between Cursor and GitHub Copilot?
Cursor is a full editor built around AI: it works across your codebase, handles multi-file edits with its agent, and offers cloud agents on its Premium plan. Copilot runs inside editors you already use (VS Code, JetBrains, Visual Studio, Xcode, and more) with completions, chat, and agent mode, plus a cloud agent that works on a branch and opens a pull request when you ask it to. Cursor requires switching editors; Copilot fits into your current one. Full comparison →
What is the difference between autocomplete and agentic coding?
Autocomplete (inline completions in GitHub Copilot or Cursor) suggests code as you type. Agentic tools (Cursor's agent, Copilot agent mode, Claude Code, OpenCode) take a task description, plan the changes, execute across multiple files, and let you review before applying. Autocomplete is faster for small edits; agentic is better for larger refactors and multi-file workflows.
Should I pick a local agent or a cloud agent?
Use a local agent (Claude Code, Codex CLI, OpenCode, Cline) when you want to watch the work in your own checkout with your own tools. Use a cloud agent (Devin, Amp, Capy, Replicas, Codex cloud tasks, Copilot's cloud agent) when you want to hand off a ticket and review a pull request later, and you can give the agent repository access and the secrets its environment needs. Many teams use both.
If an open-source coding agent is free, what does it cost?
The software is free; the model is not. OpenCode, Cline, Kilo Code, goose, and Qwen Code send your requests to the model provider you connect, and you pay that provider per token, or use a local model on your own hardware. Long autonomous tasks can use a lot of tokens, so watch usage on a real task before you commit. See OpenCode →
Should I choose an AI coding tool based purely on model strength?
No. Workflow fit matters more than raw model capability. The strongest model in the wrong interface costs productivity. Start by choosing a tool that fits how you actually work (terminal-first, editor-first, autocomplete-only, or a cloud agent) and then evaluate model quality within that kind of tool.
Is AI-generated code safe to commit to production?
No, not without review. Always carefully review AI suggestions, especially for authentication, data handling, and security-sensitive code. AI tools can introduce subtle bugs and security issues. Treat AI suggestions as a first draft that still requires your judgment and testing.
Which coding assistant is best for teams?
It depends on what the team wants to delegate. Teams adopting AI in existing editors often start with GitHub Copilot. Teams handing off tickets look at cloud agents such as Devin, Copilot's cloud agent, or Codex cloud tasks. Teams running several agents can look at JetBrains Air, which adds policies and credit limits across them, or Factory, which offers one governed agent across the delivery lifecycle. Teams with self-hosting or air-gapped requirements can look at IBM Bob, which runs on your own Red Hat OpenShift cluster. Teams wanting maximum control can run OpenCode or Cline with the model provider they choose. There is no single best tool.
Why are some coding tools marked Discontinued?
Continue was acquired by Cursor and its repository is read-only after a final 2.0.0 release, so its listing is labelled Discontinued and shown after every active tool. The Windsurf IDE plugins (formerly Codeium) still work but are in maintenance mode. Check a tool's status before building a workflow on it. See Continue →
