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.

Mercury Coder Next Edit
Sub-100ms next-edit prediction for VS Code and JetBrains — powered by diffusion LLMs

Inception Labs launched Next Edit inside the Continue extension, bringing Mercury Coder's diffusion-based architecture to VS Code and JetBrains. Unlike autoregressive autocomplete that generates left-to-right, Mercury predicts multi-line edits across your entire file simultaneously — deletions, additions, and structural changes at once. Common patterns it handles: converting callbacks to async/await, extracting functions, renaming variables across call sites, and squashing code smells. Latency is under 100ms so suggestions appear before you finish thinking. The diffusion architecture ($0.25/M input, $1/M output) is 5-10x faster than comparable autoregressive models. Available via Models Add-On in Continue.
Reviewer scorecard
“I've been managing 8 Claude Code sessions in tmux and it's chaos. ClawTab's labeled panes with per-agent status finally makes parallel agent work legible. The auto-yes mode alone saves me from interruption fatigue on long agent runs.”
“I've used next-edit features in other tools but the sub-100ms latency here is genuinely different — it's below my perception threshold, which means it doesn't break flow. The multi-line simultaneous edit understanding is real; it caught a refactor pattern I was about to manually do across 6 call sites.”
“This is a thin UI wrapper around tools that already have terminal UIs. If you're good with tmux you don't need this, and if you're not good with tmux, maybe you shouldn't be running 20 agents simultaneously. The 'manage from phone' feature sounds appealing until an agent breaks something at 2am.”
“The benchmarks are impressive but 'trained on real edit sequences' is doing a lot of work here. Until I see how it handles domain-specific refactors in large codebases with complex type hierarchies, I'm skeptical it beats Cursor's native next-edit on anything beyond textbook patterns.”
“The tooling layer around multi-agent workflows is the sleeper market of 2026. ClawTab is early but it points at the future: a developer's 'mission control' for a fleet of agents. Whoever builds the definitive version of this wins a huge surface area.”
“Diffusion LLMs applied to code editing is the most underrated architectural bet in AI tooling right now. Autoregressive generation was always the wrong primitive for editing — you don't write a diff token by token. Mercury's approach is structurally correct and the speed numbers suggest it scales without compromise.”
“I use Claude Code for everything from writing to coding and having all my sessions visible in one place with clear labels is genuinely useful. The macOS-native design feels polished compared to typical OSS dev tools.”
“Even for non-heavy-coders, the 'fix code smells' and 'rename across call sites' use cases are exactly the tedious tasks that make coding feel like work instead of creation. Sub-100ms means zero cognitive interrupt. This is the kind of AI assist that disappears into the background in a good way.”
