AI Coding Assistants with Free Trials in 2026: 9 Compared

Nine coding assistants with real free trials in 2026, and how to make the most of each.

## AI Coding Assistants with Free Trials in 2026 Free trials let you test before paying. Here is what 9 assistants offer in 2026 - and the trick to testing them fairly. ### The trials 1. **GitHub Copilot** - 30-day Pro trial, then free tier with limits 2. **Cursor** - 14-day Pro trial (Agent and unlimited completions), then free tier 3. **Windsurf** - 14-day trial with full features 4. **Codeium** - free tier always; paid trial adds premium models 5. **Aider** (47,840 stars) - open-source, no trial needed, pay only for API 6. **Cline** (65,313 stars) - open-source, bring your own key 7. **Tabnine** - 90-day trial of enterprise features 8. **Replit AI** - trial included in subscription; free tier limited 9. **Amazon CodeWhisperer (Q Developer)** - free tier, trial for pro ### How to test properly 1. Pick one benchmark task (e.g., refactor a function, write tests) 2. Run the same task in each trial 3. Compare: correctness, speed, context handling 4. Check the free tier after the trial - some remain useful ### The hidden cost to watch Most trials are per-seat with auto-renew. Set a calendar reminder to cancel before day 14/30, or switch to a free tier before it charges. ### FAQ **Which trial is most generous?** Tabnine (90 days); Copilot and Cursor (30/14 days). **Are open-source tools better?** Cline and Aider have no trials because they are free - you only pay for the model API you use.
