Pros and cons
Pros
- Deeply integrated into the IDEs developers already use
- Choice of underlying models, including Claude and GPT-5 variants
- Agent mode can carry out multi-step coding tasks, not just single-line completions
- Genuinely usable free tier before you pay anything
Cons
- Paid tiers are priced per seat and get expensive fast: Pro+ is $39/month and Max is $100/month
- Usage-based credits on premium models can run out before the month is over
- Suggested code still needs human review for correctness, security and licensing
- Agent mode can make large, hard-to-review changes if left unsupervised
Is GitHub Copilot free?
Yes — there is a free plan you can use without paying.
2,000 code completions and 50 chat requests per month, with access to a limited set of models. No credit card required.
How to use it well
Ask it to explain a suggestion before accepting it, not just autocomplete past the concept you're supposed to learn
Many CS programs restrict or ban Copilot on graded assignments -- check your course policy first
Limitations to know about
Does not replace understanding data structures and algorithms for exams and interviews
Free tier's monthly completion limit runs out faster than it looks once you're using Chat too
