Interactive Studio Wizard
Launch bun cli to access the terminal wizard. Run flows, record new sessions, execute scrapers, inspect output files, or drop into a live REPL with intuitive arrow keys.
Bflow
Ultra-lightweight, zero-bloat browser automation and visual recording studio powered by native Chrome DevTools Protocol and Bun.
Key Features
Section titled “Key Features”Live In-Browser Recorder & HUD
Record interactions directly in Chrome with a compact, keyboard-friendly HUD. Grouped step/capture menus, a target picker, and a live drawer turn interactions into clean JSON.
Human-Centric Strict Locators
Target elements directly by visible text (text="Sign In"), case-insensitive matching (text/i="..."), :text-is(), placeholder, or ARIA labels instead of fragile CSS classes.
One-Click Table & List Extraction
Click a single card or table row in your browser to auto-detect repeating structures across the page and extract structured JSON arrays instantly.
Virtual Webcam & Media Injection
Inject synthetic test pattern feeds with live UTC timestamps, local MP4/WebM video files, or remote streams directly into navigator.mediaDevices.
Live Config Inspector Drawer
Inspect JSON definitions in real-time inside Chrome, reorder steps with Up/Down buttons, delete steps, and add custom wait/goto/eval actions on the fly.
Declarative JSON Replay & CI
Replay recorded workflows in headless mode for CI/CD or headed on desktop, with dynamic variable overrides (--query="Bun") and assertions.
Agent-Assisted Authoring
Connect Codex, Claude, or another MCP host to observe, act, verify, and publish a workflow. The resulting JSON replays later without an agent or model API key.
External Data & Google Sheets
Execute one isolated workflow per row with nested variables, local transformations, filtering, bounded parallelism, retries, resume, and sparse result write-back.
Sensitive-Data Protection
Keep secrets in environment variables and redact sensitive row values from errors, summaries, saved results, screenshots, and PDFs.
Standalone Cross-Platform CLI
Install checksum-verified release binaries for macOS, Linux, or Windows without Node.js or Bun, while keeping workflows and output relative to your project directory.
Interactive Browser REPL
Inspect live pages, test CDP commands, execute JavaScript expressions, block heavy network resources, and capture screenshots in real time.
