Is LeetSRS free?
Yes. LeetSRS is free and open source under the MIT License. Install the extension and start practicing without a subscription.
Do I need an account?
No account is required for LeetSRS. Your practice data stays in your browser by default. You can optionally connect GitHub to sync it across devices.
How does it decide when I should review?
After practicing a problem, rate your recall: Again, Hard, Good, or Easy. LeetSRS uses FSRS, a spaced-repetition scheduler, to calculate your next review from that rating and your review history. The interval updates each time you review.
Which roadmaps can I follow?
Choose Blind 75, NeetCode 150, NeetCode 250, or Grind 75. LeetSRS tracks your progress and suggests the next problem, while keeping previously rated problems in your review schedule.
Can I practice problems outside a roadmap?
Yes. Open a problem on LeetCode and use the LeetSRS panel to add and rate it. Roadmaps give you a starting point, but your review queue can include other problems too.
Can I move my data to another computer?
Yes. Connect GitHub in Settings for optional sync through a gist you own. You can also export and import your practice data.
