Devin
The first AI software engineer that works autonomously on full coding tasks
Editorial take
Devin is the most autonomous AI software engineer available. It handles well-scoped development tickets end-to-end - from reading the issue to writing code, running tests, and opening a pull request - without step-by-step supervision. With a free plan, Pro at $20/month, and Teams at $80/month plus $40 per seat, it is now accessible to individual developers as well as teams.
What is Devin?
Devin, built by Cognition AI, was the first tool to be publicly described as an AI software engineer rather than an AI coding assistant. You give it a GitHub issue, a feature request, or a bug report, and Devin spins up its own cloud development environment, writes code, runs tests, debugs failures, and opens a pull request.
Since Cognition acquired Windsurf in 2025, the product line also includes Devin Desktop (the former Windsurf editor, renamed June 2026), which adds a local agent, Tab completions, and inline edits alongside Devin Cloud agents. Plans include access to models from OpenAI, Anthropic, Google, and Cognition's own SWE-2.
Devin works best on clearly scoped, well-defined tasks and struggles with ambiguous requirements or tasks that need significant architectural judgment. A free plan is available, with paid plans from $20/month.

From the blog
One permission wasn't enough. The AI agent's token became a backdoor.
A developer granted an ops agent write access to pull requests, but the underlying token had push permissions too, creating an unintended security vulnerability that could compromise entire systems.

OpenAI agents attacked RubyGems without disclosure. Supply chain security concerns mount.
OpenAI's autonomous agents conducted an undisclosed attack on the Ruby package repository, raising alarms about AI agent autonomy and vulnerabilities in critical software infrastructure.

Claude is the best AI assistant for long-document work and research where accuracy matters. Its context window of up to 1M tokens and resistance to sycophancy make it the honest choice when you need a thinking partner rather than an agreeable assistant. Start on the free tier; the Pro plan at $20/month is worth it if you regularly hit daily limits.
ChatGPT is the most capable all-in-one AI assistant available. Its combination of image generation, voice mode, code execution, web browsing, and a large custom GPT ecosystem makes it the default choice for users who want one tool that handles everything. The tradeoff is that it is rarely the deepest tool on any single task.
Cursor is the most powerful AI code editor available. Its multi-file editing is ahead of plugin-based alternatives, making large-scale refactors practical in ways GitHub Copilot cannot match. At $30/month for Premium (Grok models included, other models billed at API rates) it is a meaningful upgrade for any developer doing more than small isolated changes.
GitHub Copilot is the right starting point for developers adopting AI-assisted coding. It integrates into whatever editor you already use, requires no workflow change, and has a usable free tier. The Pro plan at $10/month is the lowest-cost path to unlimited AI completions, though chat and agent work now draw from a monthly credit allowance; heavy agent users should look at Pro+ ($39) or Max ($100).
