IDE AI apps

The open-source, provider-agnostic AI coding agent for your terminal, IDE, or desktop.

OpenCode is an open-source AI coding agent from Anomaly, the team behind SST. It runs in the terminal, a desktop app, or an IDE extension, connects to 75+ model providers through Models.dev — frontier APIs and local models alike — and stores none of your code on external servers. The optional paid Zen gateway adds a curated, benchmarked model set under one bill.

Spec-driven agentic IDE — turn prompts into specs, then code.

Kiro is AWS's agentic IDE that brings engineering rigor to AI coding. Instead of vibe-coding straight to a diff, it first generates durable spec artifacts — requirements, a technical design, and a task list — then implements them. Agent hooks automate routine actions on file events, and it runs on Claude models.

Privacy-first AI coding assistant you control — completions, chat, and agents.

An AI coding assistant built for enterprise control, offering completions, chat, and agentic workflows across all major IDEs. It never trains on or retains your code, and can be deployed as SaaS, in a VPC, on-premises, or fully air-gapped. Supports access to major LLMs plus bring-your-own and private models.

Google's open-source Gemini AI agent, in your terminal.

An open-source command-line agent that brings Gemini into the terminal for coding, debugging, content generation, and research. Ships built-in Google Search grounding, Model Context Protocol support, and project context via a GEMINI.md file, plus a non-interactive mode for scripting and CI. Free to use by signing in with a personal Google account, with paid options through AI Studio, Vertex AI, and Gemini Code Assist.

OpenAI's open-source coding agent for the terminal.

A lightweight, open-source coding agent that runs locally in your terminal, reading your repository, editing files, and running commands in a conversational loop you review in real time. Built in Rust for speed, it supports Model Context Protocol tools, subagents for parallel tasks, and switching between GPT models. Sign in with a ChatGPT plan (Plus, Pro, Business, Edu, or Enterprise) or use an OpenAI API key.

Self-hosted AI coding assistant — an on-prem Copilot alternative.

Open-source, self-hosted code-completion and answer engine that teams run on their own infrastructure for full data control. Ships IDE extensions for VS Code, JetBrains, and Vim plus an in-IDE chat. The core is Apache-2.0; enterprise features (SSO, seats) live in a separately licensed 'ee/' directory.

AI pair programmer in your editor — completions, chat, and agents.

The original in-editor AI coding assistant, offering multi-line completions, chat with codebase context, agent mode, and a cloud coding agent that opens pull requests. Runs across VS Code, JetBrains, Visual Studio, the CLI, and GitHub.com. A free tier covers light use; paid tiers add premium models and more allowance.

Free AI-native IDE with an autonomous build mode.

VS Code-based AI IDE from ByteDance whose Builder/SOLO agent plans tasks, edits across files, runs commands, and previews results. Bundles access to frontier models like Claude, GPT, Gemini, and DeepSeek without requiring your own API key, on free and paid usage tiers.

Agentic development platform built on a VS Code fork.

Google's agent-first IDE where autonomous agents plan, execute, and verify coding tasks across the editor, terminal, and browser. A Manager view orchestrates multiple agents in parallel, and agents produce Artifacts — task lists, plans, screenshots, browser recordings — so you can check their work at a glance. Launched in public preview alongside Gemini 3.

Agentic coding assistant tuned for large, multi-repo codebases.

Augment Code is an AI coding platform whose Context Engine indexes large, multi-repo codebases so its completions, chat, and agents reason across cross-file dependencies. It runs as a VS Code and JetBrains extension, a CLI, and asynchronous remote agents, and targets engineering teams working in enterprise-scale repositories.

The fast, open-source AI code editor in Rust, from the Atom creators.

A GPU-accelerated, Rust-built editor with first-class agentic AI — parallel agents, edit prediction, and an open Agent Client Protocol that plugs into Claude, GPT, Gemini, MCP servers, and external CLI agents like Claude Code. Fully open source (GPL-3); BYO key or an optional hosted Pro tier.

Open-source AI coding assistant for VS Code, JetBrains, and the CLI.

An open-source AI coding assistant delivered as a VS Code extension, a JetBrains plugin, and a CLI, with chat, autocomplete, and agent workflows. It runs locally in your editor and works with any model provider, including local models via Ollama, using your own keys. The core is Apache-2.0 and free; the company also offers a hosted Continue Hub for sharing and managing assistants.

Agentic development environment born out of the terminal.

A modern terminal and agent platform — multi-agent orchestration, codebase indexing, a built-in editor (Warp Code), and granular permission controls for running coding agents. Adds the Oz cloud layer for remote agent execution and team knowledge via Warp Drive. Free tier with monthly AI credits; paid Build/Max/Business plans add more credits and BYOK.

AI-first code editor. Multi-model, tab-completion native.

Fork of VS Code with deep model integration — multi-line tab completion, agent mode, chat with codebase context. Strong for fast iteration on existing repos.

Cascade agent + IDE. Codeium's developer surface.

Agent-first IDE that pairs autocomplete with Cascade, a planning-then-acting agent. Strong terminal integration; good when the diff spans many files.

Anthropic's official CLI / IDE / web agent.

Anthropic's agentic coding tool. It reads the spec, drafts the diff, runs the tests, and opens the PR — across the CLI, IDE extensions, the desktop app, and the web.

Terminal-native pair programmer. BYO key, BYO model.

Open-source CLI for AI pair-programming directly against your git repo. Brings any model (Claude, Gemini, GPT, local) into a tight commit-per-task loop.
