24 alternatives to Openleetcode – Local LeetCode runner where tests live in the repo
You write a standard solution, just like on LeetCode, and run it through the CLI. It identifies the problem by ID or title, executes your code against local test cases, and shows the result. It currently supports around 1.4k problems and multiple languages, including Python, C++, Rust, Java, Go, TypeScript, Swift, and others. The project is still an MVP. System design, SQL, and concurrency problems are not supported yet, but support for more problem types is planned. Made in Haskell!
Openleetcode is a local command-line tool that runs LeetCode-style coding problems with test cases stored in a repository. Users write solutions in supported languages like Python, Rust, Java, Go, TypeScript, and… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

Hi HN — I’m learning Rust and decided to build a universal CLI for running code in many languages. The tool, Run, aims to be a single, minimal dependency utility for: running one-off snippets (from CLI flags), running files, reading and executing piped stdin, and providing language-specific REPLs that you can switch between interactively. I designed it to support both interpreted languages (Python, JS, Ruby, etc.) and compiled languages (Rust, Go, C/C++). It detects languages from flags or file extensions, can compile temporary files for compiled languages, and exposes a unified REPL…

As you solve LeetCode questions, you can mark them as hard, medium, or easy. The tool will then recommend questions you should review based on (1) how hard the question was for you and (2) how much time has passed since you last reviewed it. I'd recommend normally attempting LeetCode problems and just marking them as hard, medium, or easy for you at first so the tool knows which problems to recommend you review! Here's the theory behind spaced repetition and learning if interested: https://www.codecademy.com/article/spaced-repetition

I've long had a dislike for leetcode interviews on both sides of the coin. Project-based interviews can also be challenging because it can end up filtering out folks who don't want to spend several hours building something in their free time. I met up with a friend last year -- a very senior dev -- who had taken some time off to study leetcode exercises while preparing for FAANG interviews. It struck me that one of the key measures of whether a candidate is a fit for a team is rather synthetic. CodeRev.app is a simple, lightweight tool that helps teams evaluate candidates using code reviews.…

Hi HN! I’m so excited to show my first open-source project and first post here. I initially started this project to learn Go language, it is an experimental project. The main goal is to track the adventure of a WebRTC stream from start to finish, by debugging the project or tracking the output at console. By trying out this project, you will deep dive into the steps which are taken while starting up a WebRTC session, and more. It consists of a web UI (TypeScript) and a server back-end (Golang) projects. They can run on Docker containers, in development mode or production mode, you can find…

Hi everyone, I built a runtime to isolate untrusted code using wasm sandboxes. Basically, it protects your host system from problems that untrusted code can cause. We’ve had a great discussion about sandboxing in Python lately that elaborates a bit more on the problem [1]. In TypeScript, wasm integration is even more natural thanks to the close proximity between both ecosystems. The core is built in Rust. On top of that, I use WASI 0.2 via wasmtime and the component model, along with custom SDKs that keep things as idiomatic as possible. For example, in Python we have a simple decorator:…

We're excited to share a tool we've been working on called gpt-code-search. It allows you to search any codebase using natural language locally on your machine. We leverage OpenAI's GPT-4 and function calling to retrieve, search, and answer queries about your code. All you need to do is to install the package with `pip install gpt-code-search`, set up your `OPENAI_API_KEY` as an environment variable, and start asking questions with `gpt-code-search query `. E.g. You can ask questions like "How do I use the analytics module?" or "Document all the API routes related to authentication." This is…

I am super excited to open-source the code executor behind logicboard.com - an in-browser collaborative code editor. The backend is written in Elixir+Phoenix and implements a WebSocket API to execute code in docker containers. Next steps include making this more secure, I am considering Google's gVisor to implement better isolation between containers and the host kernel.
