The verdict
Pick Windsurf if…

Pick OpenAI Codex if…
- →overall capability matters more than price (AI Score 8.8 vs 7.2)
- →your primary use case is teams already standardised on chatgpt who want the coding agent bundled with the seats they pay for, and who want the same agent in a terminal, an editor and a pull request.
- →you need: productivity

Pros and cons
Windsurf
Coding · freemium
Pros
- ✓Cascade remains one of the better-designed agent loops: it plans, edits across files, runs commands, reads output and iterates without needing constant re-prompting
- ✓Repo-wide indexing means the agent locates the relevant files itself instead of making you paste context
- ✓Mixes cheap in-house SWE-series models for routine edits with frontier models for hard problems, so agent runs are not uniformly expensive
- ✓Enterprise self-hosted and air-gapped deployment with zero data retention, which Cursor does not offer at any tier
- ✓Full VS Code fork with terminal execution and file-write access, not a chat sidebar bolted onto an editor
Cons
- ×The founding team including CEO Varun Mohan left for Google DeepMind in July 2025 and Cognition bought what remained, so an independent product roadmap is not a safe assumption
- ×windsurf.com resolved to Cognition's Devin site when checked on 2026-08-10, meaning the plans a buyer actually encounters are Devin's and no Windsurf-branded price could be confirmed on any live page
- ×Cursor and Claude Code have caught up on multi-file agentic work, erasing the 2025 lead this entry's original 9.1 score was built on
- ×Pricing is credit-metered and hard to forecast for a team; the unlimited free tier that once made the product an easy recommendation is gone

OpenAI Codex
Coding · freemium
Pros
- ✓Included in ChatGPT plans from the free tier upward, so most organisations already own it
- ✓Covers the terminal, the editor, a hosted cloud runner, the ChatGPT apps and GitHub pull request review from one entitlement
- ✓AGENTS.md keeps agent configuration in the repo and under version control rather than in someone's local settings
- ✓Three GPT-5.6 variants let a team route cheap work to Luna and hard work to Sol instead of paying one rate for everything
- ✓Overflow credits are priced per million tokens, which makes the marginal cost of extra work legible
Cons
- ×Published limits are ranges per rolling five-hour window that span two orders of magnitude, so the included allowance is not knowable in advance
- ×Usage depends on which model variant a task routes to, and routing is not fully under the user's control
- ×Pro pricing is presented as tiers rather than a single figure, so the real cost of the heavy plan needs checking at the point of sale
- ×The agent is tied to a ChatGPT account, which is awkward for teams that standardised on a different assistant vendor
