A friendlier place to start, not a replacement for LeetCode
LeetCode is the standard for interview-focused practice: thousands of problems, tagged by company, built for people cramming for a specific job. Open Bracket is something else. One attainable challenge a day, chosen for you, built for making practice a habit rather than a grind. Here's an honest look at where each one fits.
Where LeetCode is the better tool
If you're actively interviewing at a specific company this quarter, LeetCode's company-tagged question bank is hard to beat. It organizes thousands of problems by the exact companies and topics that show up in real interview loops, with detailed test cases and years of community discussion on every problem.
It's also the deepest catalogue around. If what you want is exhaustive coverage of every algorithm pattern, LeetCode has it.
We're not trying to be a bigger catalogue
Open Bracket doesn't start with a catalogue to pick from. One challenge a day, the same one for everyone. No scrolling through thousands of problems trying to work out which "easy" one is actually easy for where you are. Read more about how the daily rhythm works →
Reading the problem and testing your code against the sample tests is free for anyone, no account required. A pseudo-code hint is there if you get stuck. It walks through the shape of a solution without handing you the answer.
Same goal, different shape
LeetCode
3,000+ problems, organized by company and topic.
You choose what to solve and when.
One acceptance-rate leaderboard per problem.
Open Bracket
One challenge a day, chosen for you. The same one for everyone.
A difficulty rhythm that ramps through the week.
Three leaderboards: Speed, Efficiency, Code golf.
Advanced is calibrated to the difficulty band LeetCode is known for
Standard is the attainable daily rhythm above. Once you've outgrown that pace, Advanced sits alongside it every day. It pulls from the same Easy/Medium difficulty band LeetCode's own problems are known for. It's a natural next step if LeetCode-style problems are where you're headed, without throwing you in cold.
What people usually ask
Is Open Bracket free?
Yes. Reading today's challenge and testing your code against the sample tests is free for anyone, no account needed. Creating a free account unlocks your streak, your history, and a shareable result link.
Should I use LeetCode or Open Bracket to prepare for interviews?
If you're actively interviewing at a specific company soon, LeetCode's company-tagged question bank is the more targeted tool for that. Open Bracket is built for something different. It's a steady, low-pressure daily habit. Plenty of people use both.
I'm just starting to learn to code. Is LeetCode too advanced for me?
LeetCode's catalogue can be genuinely overwhelming with no clear entry point, which is exactly the gap Open Bracket fills: one challenge a day, chosen for you, with a difficulty rhythm that ramps gradually through the week.
Can I solve challenges in Python and JavaScript?
Yes, on both platforms. Pick whichever you're most comfortable in.
