ClawTab vs DeepGEMM

ClawTab is a macOS desktop app that turns managing multiple AI coding agents from a terminal circus into an organized workflow. Built by indie developer Tõnis Tiganik, it provides a proper GUI for running Claude Code, Codex CLI, and OpenCode in parallel — with a sidebar showing per-agent status, pane splitting, auto-yes passthrough, and the ability to trigger agent restarts from your phone. The core problem it solves: once you start running more than 3-4 coding agents simultaneously, tmux panes become unreadable and you start losing context on which agent is doing what. ClawTab gives each agent a labeled tab with status indicators, scrollable history, and the ability to quickly switch contexts without losing your place. It's the kind of tool that only makes sense in a world where shipping a feature means spinning up 10 agents on 10 tasks at once — and that world is arriving fast. Version 1.0 launched on Product Hunt today and is already getting traction from the vibe-coding crowd.

DeepGEMM is DeepSeek's open-source library of highly optimized FP8 General Matrix Multiplication (GEMM) kernels targeting NVIDIA SM90/SM100 GPUs — the H100, H800, and Blackwell class. The headline feature is a lightweight just-in-time (JIT) compiler that eliminates the need for offline CUDA compilation at install time, dramatically lowering the barrier for teams who want raw GPU throughput without complex build pipelines. The library covers FP8 and FP4 dense GEMMs, BF16 accumulation, grouped GEMMs for Mixture-of-Experts architectures with overlapped NVLink communication, and multi-query attention scoring kernels. On H800 hardware DeepGEMM posts up to 1,550 TFLOPS — competitive with hand-tuned vendor libraries — while remaining fully open source under the MIT license. For LLM inference teams running on H100/H800 clusters, DeepGEMM slots directly into inference stacks like vLLM and SGLang. It's especially notable because it came from DeepSeek's internal training infrastructure, meaning it's been battle-tested at the scale that produced some of 2026's most cost-efficient models. This isn't research code — it's production tooling going public.
