Pros and cons
⌨️
Claude Code
Coding · freemium
Pros
- ✓Included on every Claude plan including the free one, so trying it costs nothing beyond an account
- ✓No backend server and no remote code index, which removes a whole category of question from a security review
- ✓Permission prompts before file edits and command execution keep the agent's blast radius under the developer's control
- ✓Same entitlement covers terminal, IDE, Slack, web and mobile rather than charging per surface
- ✓Routines turn the agent into a scheduled or event-driven job, not just an interactive session
Cons
- ×Anthropic publishes no Claude Code specific usage limit, only the line "Usage limits apply", so the practical ceiling is unknown until you hit it
- ×The pricing page shows "From $100 per month" for both Max 5x and Max 20x, which makes the step between them impossible to read from the page
- ×Terminal-first workflow assumes comfort with a shell and with reviewing diffs, which is a real barrier for people used to a graphical editor
- ×Parallel subagent fan-out consumes usage quickly, and the cost of a large run is not visible before you start it

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
