Windsurf alternatives (2026)

AI coding agent built into a VS Code-style editor. Cursor combines inline Tab autocomplete, an in-editor Agent that edits across files, and Cloud/Background Agents that run remotely (launchable from the editor, Slack, GitHub, or via API) to fix bugs and open pull requests on their own.

Devin is Cognition's autonomous AI software engineer. You assign it a task or ticket (via web, Slack, Linear/Jira, or API) and it plans, writes code, runs commands in its own cloud VM, and opens pull requests largely without supervision. I

AI coding agent and pair programmer embedded in your IDE, terminal, and GitHub. Offers inline code completions, chat, an autonomous agent mode, a cloud-based coding agent that opens pull requests, and automated code review, with a choice of models from OpenAI, Anthropic, and Google.

Enterprise autonomous software development platform. Blitzy orchestrates 3,000+ specialized AI agents in parallel across multiple frontier models (Claude, GPT, etc.), grounding them in a knowledge graph it reverse-engineers from your existing codebase to autonomously build, refactor, and modernize software at scale.

Lovable is an AI app and website builder built around "vibe coding": you describe what you want in plain language and it generates a working full-stack app with a React/Tailwind frontend, Supabase backend, Stripe payments, and GitHub sync. It is prompt-to-app, with usage metered in credits per AI message. The company raised a $330M Series B in 2025.

Base44 is a chat-based, no-code AI app builder that turns plain-language prompts into full-stack web apps, handling the database, authentication, backend functions, and deployment behind the scenes. Acquired by Wix in June 2025, it targets non-developers who want working internal tools and SaaS-style apps without writing code. Pricing runs on a two-currency credit system: message credits for AI build prompts and integration credits consumed when end users trigger features like LLM calls, email, or file uploads.

CodeRabbit is an AI code-review agent that auto-reviews every pull request, leaving line-by-line comments, summaries, and one-click autofixes. It plugs into GitHub, GitLab, Azure DevOps and Bitbucket, and also runs reviews in your IDE and CLI before code is even pushed. Pricing is per developer, with a free tier and free reviews forever on public repos.

Anthropic's agentic coding tool that lives in your terminal, IDE (VS Code, JetBrains), and the web. It reads your whole codebase, edits files, runs commands, and ships changes through git on its own. Access comes bundled with a Claude Pro/Max subscription or via pay-as-you-go API usage on a Claude Console account.

OpenAI's agentic coding tool that runs as a terminal CLI, an IDE extension, a cloud agent, and inside ChatGPT, all sharing the same account. It is not sold on its own: access is bundled into ChatGPT subscriptions (Plus, Pro, Business, Enterprise) and is also available pay-as-you-go through the OpenAI API with an API key. It runs OpenAI's GPT-5.x and GPT-5.x-Codex models to read, write, run, and refactor code across local and cloud environments.

Cline is an open-source (Apache 2.0) autonomous coding agent that runs as a VS Code extension, a JetBrains plugin, and a CLI. The extension itself is free with no subscription or seat fee; you pay only for AI model usage, either by bringing your own provider API keys or by buying credits through the optional Cline provider. It emphasizes no vendor lock-in, a Plan/Act workflow with human approval, and an MCP marketplace for connecting tools.

Aider is a free, open-source AI pair programmer that runs in your terminal and edits code in your local Git repo with automatic commits. The tool itself costs nothing; you bring your own LLM API key and pay the model provider directly, so spend scales with usage. It connects to almost any model, including local ones via Ollama for near-zero cost.
