Automated LeetCode Redo Lists From Failures
Every night, WebRun opens LeetCode, reads today's submissions, keeps the ones that did not pass, groups those problems by topic tag and difficulty, sends you the redo list on Telegram, and posts a short weak-area note to your study group in Slack.
How do I build a practice list from LeetCode problems I failed?
WebRun opens LeetCode each night and reads the day's submissions, keeping only the problems that did not pass. It groups them by topic tag and difficulty, sends you the redo list on Telegram, and posts your weak topics to your study Slack, so tomorrow's practice targets what you actually missed.
- Missed problems come back the next day instead of being forgotten
- Practice is grouped by the topic that actually failed
- Solved-on-retry problems drop off the list automatically
Built for software engineering candidates · interview prep groups · computer science students · bootcamp cohorts

How is each run configured?
Secure by default
Connect once, stays signed in
WebRun signs in once and keeps each session in a persistent environment, so every run picks up right where it left off.
Every action is checked against this policy before it runs.
Questions, answered
Does it submit or run any code for me?
No. WebRun reads your submission history and builds a list. It never writes, runs, or submits a solution, and your practice stays your own work.
What if I solved the problem on a later attempt?
It is dropped from the list. WebRun checks whether any submission for that problem was accepted today before adding it to tomorrow's redo set.
Is my code shared to the Slack channel?
No. The Slack post names only the topic tags and how many problems fell under each. Your submitted code is never read out or shared anywhere.
