Paneflow runs on Windows now. Five days porting a GPU-native terminal across the Unix/Win32 line: named pipes where Linux had Unix sockets, a rebuilt PTY layer, same GPUI rendering, no WSL. Today it runs, and I'm proud of it. Windows is still where most developers work, and most agent terminals are macOS-only. Paneflow now runs on all three. I use it every day to build itself. Still open source. Still free. repo: github.com/ArthurDEV44/panef… download: paneflow.dev

Paneflow v0.4.0 is out. The headline: Paneflow is now scriptable. The new paneflow CLI drives the whole app over IPC. paneflow up spins up a complete agent workspace from one declarative spec. paneflow flow runs agent pipelines from a flow.toml: readiness barriers, fanning a step out over a list, capturing output between steps. Nothing ever gets submitted to an agent unless you explicitly allow it. One git worktree per agent. Declare worktree = "branch" and every agent gets an isolated checkout: .env files copied, a port offset per pane, automatic cleanup when the workspace closes. Parallel agents stop stepping on each other's diffs. The grid routes your attention. A waiting agent glows, the desktop notification carries its actual question, and Ctrl Shift J jumps straight to the next agent that needs you. And a UX pass on the whole app: the Agents view is rebuilt as a cockpit, rails now run the full window height, the title bar floats, the chrome is quieter. Free and open source. Linux and macOS today, Windows in progress. lnkd.in/e3MBvBwf

Paneflow 0.3.9 is out. Terminal engine rebuilt on upstream alacritty_terminal: OSC 8 hyperlinks, cursor shapes, a live scrollbar, exit status reporting. Plus two full audit passes, security and correctness, both remediated, and a hardened updater. Linux and macOS, Windows in progress. Free and open source. github.com/ArthurDEV44/panef…

New post: hardening the subsystem that actually runs your CLI agents. 49 fixes in Paneflow v0.3.4: memory, security, perf, robustness. The kind of unglamorous work nobody demos. Reliability lives in the harness, not the model. Read it 👇 drop a comment if it clicks. dev.to/arthurj-dev/hardening…

New in Paneflow: a diff your agents can review. It shows the Git diff of your current branch in your workspace, file by file. Switch to the Worktree view and all your worktrees line up side by side, one column each, so you read what every branch is doing at once, no checkout. Switch to Multi-project and every repo you have open becomes a tab, so you move across projects without leaving the diff. Then hit Review on any column. Paneflow opens your agent in a terminal under the diff, Claude Code or Codex or whatever you run, with a review prompt already typed in. You read it, you hit Enter, it reviews that branch. Free and open source. paneflow.dev

New in Paneflow: a files sidebar. It shows the file tree of your current workspace. Drag and drop a PRD or any markdown file into a pane and it renders right there, next to your agent. You can also copy any file's full or relative path with a right click, so no more digging through a file explorer. No second editor on the side. Everything stays in Paneflow. Free and open source. paneflow.dev

Shipped a small quality of life feature in Paneflow this week. Resuming an agent session used to mean reopening Claude Code, Codex, or OpenCode and retyping the /resume command every single time, just to get back into work you already started. So I added a sidebar with all your past sessions, grouped by project, one click away. No flag to remember, no session ID to dig up. You click, you land right back where you left off. Paneflow 0.3.6. Free and open source. paneflow.dev

Every VC had a reason Vercel shouldn't exist. Guillermo Rauch heard a different reason from every investor he spoke to when building Vercel, and he kept going anyway. He joined us live at Mercury HQ in SF for Founders in Arms, and this was one of the sharpest moments in the conversation: the idea that consensus is a signal to walk away, not lean in. Full conversation with Guillermo Rauch (CEO, Vercel) on the latest Founders in Arms episode. Link in bio.

Found an O(n²) in Paneflow's markdown streaming: every render tick rebuilt the whole string. 5 agents at once = 30-50% of a core wasted. Fix = one additive String buffer. ~38x throughput, zero rewrite. v0.3.4, free OSS: github.com/ArthurDEV44/panef…

Paneflow v0.3.3 shipped. The v0.3.x story: a new "Agents" interface inspired by the Codex App. Renders both markdown chat and terminal threads. Claude Code and Codex in a dedicated panel, alongside the classic CLI mode. paneflow.dev

Paneflow talks to Claude Code, Codex, and OpenCode through one Rust runtime. Same launcher in the tab bar. Same persistent threads. Same keybindings. Switch agents without switching apps.

Wrote up the architecture behind Paneflow: a native Rust terminal workspace for running Claude Code, Codex, and OpenCode in parallel panes. Built on Zed's GPUI engine: dev.to/arthurj-dev/building-…

Paneflow is now on macOS. Windows next. paneflow.dev

Distill v0.10.1 - two papercuts gone. code_execute no longer crashes on scripts without a return. console.log just works. smart_file_read skeletons stop printing async async on TS functions. v0.10 last week, polish this week. distill-mcp.com

Paneflow v0.2.9 - agent badges now have a brand. Claude Code in salmon, Codex in indigo. Amber when waiting, mint when done. Sidebar tells you who needs you, at a glance. Dev prod builds coexist now too. Linux now, macOS/Windows next. paneflow.dev

Paneflow v0.2.8 - 7 releases in 7 days. Run Claude Code or Codex in a pane and watch the agent state live in the sidebar: thinking, waiting, done. Pixel-perfect rendering with @zeddotdev. Click-to-restart updates. Linux now, macOS/Windows next. paneflow.dev

Introducing Paneflow Terminal multiplexer for running Claude Code & Codex in parallel: - Persistent workspaces - Auto-detect AI agents - Port scanning - Zero keystroke latency Rust Zed's GPUI engine. Linux out now, Windows/macOS soon. Open source. paneflow.dev
