Bolt.new

StackBlitz · Coding Agents

Bolt.new is a browser-based full-stack agent that scaffolds, runs, and deploys complete web applications from a single prompt — no local setup required. Built on StackBlitz's WebContainers, it has become the leading "vibe coding" tool for rapid prototyping and has spawned an ecosystem of open-source forks. It is especially popular with non-developers and startup founders who want functional MVPs without writing code.

Aider

Paul Gauthier · Coding Agents

Aider is the most popular open-source terminal-based coding agent, enabling AI-assisted pair programming directly in your CLI. It maps your repository with a tree-sitter code graph and surgically edits files while automatically creating git commits for every change. Aider supports virtually every major LLM via API and is the go-to choice for developers who want full control without a GUI.
