24 alternatives to Supermaven, the first code completion tool with 300k token context
Supermaven is the fastest copilot with the longest context window.
Supermaven is a code completion tool for developers. It uses a 300k token context window, which allows it to understand and reference significantly more of a codebase than traditional code completion tools. This… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

Superset▲541Hey HN, we’re Avi, Kiet, and Satya. We’re building Superset, an open-source terminal made for managing a bunch of coding agents (Claude Code, Codex, etc) in parallel. - Superset makes it easy to spin up git worktrees and automatically setup your environment - Agents and terminal tabs are isolated to worktrees, preventing conflicts - Built-in hooks [0] to notify when your coding agents are done/needs attention, - A diff viewer to review the changes and make PRs quickly We’re three engineers who’ve built and maintained large codebases, and kept wanting to work on as many features in…

I'm Varun from the Codeium team. After support for VSCode, Jetbrains, Jupyter, and Colab, we are super excited to bring free AI-powered code autocomplete to Vim and Neovim. And in the spirit of Show HN, we have a playground version for anyone to try the tech in the browser without any installation (https://www.codeium.com/playground)! We also made the vim client open source and are open to contributions.

Context Gateway▲220We built an open-source proxy that sits between coding agents (Claude Code, OpenClaw, etc.) and the LLM, compressing tool outputs before they enter the context window. Demo: https://www.youtube.com/watch?v=-vFZ6MPrwjw#t=9s. Motivation: Agents are terrible at managing context. A single file read or grep can dump thousands of tokens into the window, most of it noise. This isn't just expensive — it actively degrades quality. Long-context benchmarks consistently show steep accuracy drops as context grows (OpenAI's GPT-5.4 eval goes from 97.2% at 32k to 36.6% at 1M…

TokenDagger is a drop-in replacement for OpenAI’s Tiktoken (the tokenizer behind Llama 3, Mistral, GPT-3.*, etc.). It’s written in C++ 17 with thin Python bindings, keeps the exact same BPE vocab/special-token rules, and focuses on raw speed. I’m teaching myself LLM internals by re-implementing the stack from first principles. Profiling TikToken’s Python/Rust implementation showed a lot of time was spent doing regex matching. Most of my perf gains come from a) using a faster jit-compiled regex engine; and b) simplifying the algorithm to forego regex matching special tokens at all.…

SuperCraft▲283Hi there, SuperCraft is generative AI tool for industrial designers. It offers a collaborative node based canvas where users can sketch, and convert the sketches to high quality 2D and 3D renders of their products. It looks like if Figma and ComfyUI had a baby. With SuperCraft, designers can generate sketch ideas from textual descriptions of the product, or directly draw on the canvas, or upload images of their sketches. They can further enrich the sketches and turn them into highly realistic renders of the products using textual descriptions. The renders generated are both 2D and 3D, and…

Substage▲183Hey all! I’m a solo indie dev and I’ve been working on Substage – a Mac app that docks under your Finder window and lets you interact with your files using natural language. Stuff like: • Convert to webp • zip these up • Author of this PDF? • Download this file: • Is this really a PNG? • What's 5 foot 9 in cm? • Open in TextMate Substage converts your prompt into a Terminal command using an LLM (GPT-4o, Claude, Gemini, Mistral, or your own local model), runs it, and summarises the output. If it detects something risky, it’ll pause for confirmation before running. Commands run locally on your…

Hey, HN! I was trying to find a good Copilot alternative since my experience with copilot degraded a lot and recent OpenAI drama leaves me no hope for improvement and i decided to take a look at self-hosting options. At the same time Copilot net is a small one - just 12b parameters and 2k of context. You can run much bigger networks locally in 2023. I have figured out that there are no good local options: most of the VS Code plugins simply connect neural networks to the code while copilot has extensive post and pre processing steps. Some of them still work with original copilot plugin (ie…

Henry, Matt and James here – we’re building an open source toolkit that makes it easy to integrate an LLM-powered copilot that talks to your API into software products. It works by calling API endpoints which you choose to expose to it. This lets the chatbot complete tasks within your software in response to natural language queries. It’s also open source, so you don’t have to send user data to another 3rd party. We support Llama 2, but we haven’t fine-tuned Llama 2 yet (coming soon) so highest accuracy is seen with GPT-4 or fine-tuned GPT-3.5 (much faster). We started working together 2…

Hi HN! We’re MutableAI (YC W22) (https://mutable.ai). Our mission is to reduce the time and cost to create high quality code using AI. We have worked at the full gamut of companies ranging from startups to big tech and have gotten the sense that many of the rote aspects of software development could be made easier, freeing up precious mental energy. Devs love Copilot, but autocomplete is just one of many ways that AI should make programming easier. We’re taking a more comprehensive approach to developer tooling that bundles Copilot-like autocomplete with documentation, custom AI…

Scapefree tier, from $9.99/mo▲59Hey HN, we've been using Claude Code daily for months, and built Scape to fix our biggest pain point: managing multiple worktrees quickly & reducing the mental load of switching between them quickly. What we built: Scape is a macOS menu bar app that sits on top of Claude Code and gives you: - One-click worktrees: click a button, get a new git worktree with a Claude session already working on it. Develop in parallel without leaving your current branch. - Toolkit: per-session actions like "Create PR", "Commit & Push", "Run & Fix Tests." Add your own with bash scripts or prompts. -…
