Created by StackBlitz, Bolt is an AI web development sandbox. It doesn’t just write code; it boots up an entire Node.js environment in your browser, installs dependencies, and runs the app.

The Best AI Terminal & CLI Tools

5. Warp

Warp is a modern, Rust-based terminal that features built-in AI block commands. Instead of googling tar commands, you simply ask Warp’s AI to execute the exact file operation you need.

6. GitHub Copilot CLI

Brings the power of Copilot directly to the terminal. It helps translate natural language into shell commands and explains what cryptic shell scripts actually do.

The Best Autonomous AI Agents

7. Devin

Billed as the “first AI software engineer,” Devin can plan, write, test, and deploy code autonomously. It operates its own sandbox environment to complete complex GitHub issues.

8. Aider

An open-source, command-line AI pair programmer. Aider is incredibly effective at modifying code inside your local git repository and auto-committing the changes with descriptive messages.

This is just a small sample of what’s available. The best tool for you depends entirely on your tech stack, budget, and workflow preferences.
