How to Choose a Coding Agents Tool
Key criteria to evaluate when comparing Coding Agents solutions:
About Cursor
Cursor is an AI-native code editor built as a fork of VS Code, designed from the ground up for AI-assisted development. Created by Anysphere, a company founded in 2022 by Michael Truell (CEO), Sualeh Asif, Arvid Lunnemark, and Aman Sanger, Cursor has become the fastest-growing SaaS product in the AI coding space.
The editor features intelligent code completion, multi-file editing, codebase-aware chat, and an agent mode that can autonomously plan and execute coding tasks. Cursor indexes your codebase to create vector representations for accurate, project-specific suggestions rather than generic code. It supports 26 LLMs from OpenAI, Anthropic, Google, xAI, and DeepSeek, with quick integration of new models as they release.
Cursor reached $100 million ARR in January 2025 within 20 months of launch, growing to $500 million ARR by November 2025. The company raised $3.5 billion in total funding at a $29.3 billion valuation. With over 1 million daily active users and 50,000+ business customers, Cursor has a thriving community of 73,000+ subreddit members and 30,000+ GitHub stars.
About OpenAI Codex
OpenAI Codex is a cloud-based autonomous coding agent that runs in a sandboxed environment. Built on GPT-5.3-Codex, it can read codebases, write and edit code across multiple files, run tests, and submit pull requests from natural language task descriptions. Codex operates asynchronously, handling tasks in parallel while developers focus on other work.
The product is available through ChatGPT subscriptions (Plus at $20/month, Pro at $200/month) and via the API using codex-mini-latest at $1.50/1M input tokens and $6.00/1M output tokens. Codex supports both cloud sandbox and local terminal execution modes.
OpenAI was founded in 2015 and is headquartered in San Francisco. The company is valued at approximately $500-730B and is preparing for an IPO that could value it at up to $1 trillion.
