Testers.AI turns your iPhone into a professional QA engineer. Tap the Safari extension on any web page and AI agents immediately get to work โ€” clicking, scrolling, filling forms, and probing for problems like a seasoned tester would. When they're done, a detailed bug report lands in the app: every issue ranked by severity, with steps to reproduce, screenshots, expected vs. actual behavior, and AI-generated fix suggestions. INTELLIGENT EXPLORATION Choose from eight exploration styles โ€” Happy Path, Smoke, Negative, Edge Case, Scenario, Monkey, Adversarial, and Destructive โ€” and focus the agents on what matters most: accessibility, security, performance, UX, forms, navigation, or content. The agents adapt their behavior to the style and focus you select. MULTI-AGENT TESTING Run up to several AI agents in serial across the same page. Each agent brings a different testing persona and approach, giving you broader coverage than any single pass could achieve. BATCH MODE Test an entire list of URLs in one go. Paste them in, or just describe what you want ("top e-commerce checkout pages") and let the AI generate the list for you โ€” even by voice. Results land in a competitive comparison view so you can see which sites have the most issues at a glance. DETAILED REPORTS Every exploration session is saved to your history with: โ€ข Issues sorted by severity (Critical โ†’ Suggestion) โ€ข Agent step-by-step replay โ€ข AI summary of what was found โ€ข Hero stats: issues found, steps taken, agents used EXPORT ANYWHERE Share results as plain text, JSON, or JIRA wiki markup โ€” ready to paste straight into your bug tracker. Copy individual issues, share full reports, or export a screenshot of the results to send to your team. ISSUES DASHBOARD The Issues tab organizes every bug found across all your sessions by domain and URL, so you can track quality trends across the sites you care about over time. BATCH COMPARE Run the same test across multiple competitors or pages, then review a side-by-side bar chart ranking them by issue count and severity. Great for competitive audits and regression checks before launch. PRIVACY FIRST All exploration history is stored locally on your device. No account required to get started. Testers.AI is built for developers, QA engineers, product managers, and anyone who cares about shipping quality software. Unlock full access with your Testers.AI account for unlimited testing and team sync.

Multiplex

Multiplex is a terminal for people who live inside persistent remote sessions โ€” open source, built native for iPhone and iPad. THE WALL Hosts probe concurrently. Every session is a live monitor: its actual last screen lines, red LIVE while attached. See the fleet before attaching; NO SIGNAL reconnects in one tap. Run tmux, or switch a host to herdr โ€” one tile per session, agent state from herdr itself. A SESSION WHERE YOU NEED IT On iPad each session opens in a real scene for Stage Manager, Split View, and external displays. Merge windows into tabs and split them back out โ€” the SSH connection and scrollback move with the tab, so shells never drop. On iPhone, the wall and terminal share one adaptive full-screen shell. BUILT FOR AI AGENT SESSIONS Start Claude Code, Codex, Pi, Grok Build, Antigravity CLI, or Hermes with a setup script, model, and first prompt in one step. Multiplex spots all six in any pane; helper chips follow the foreground agent โ€” commands reach the process receiving your keystrokes; rearrange or add your own, synced everywhere. A message box takes longer prompts: autocorrect, dictation, attached or dropped files land in the pane's directory, sent as one message. Pro lifts the daily chip limit, alerts you when an unwatched turn ends or needs input (Claude Code, Codex, Grok Build on tmux; all agents on herdr), and opens Claude Code prompt history with transcript jumps. FILES & LINKS BESIDE THE TERMINAL Tap a link or path โ€” Multiplex confirms the resolved target first. Files open read-only in the โ–ค File Viewer: code, rendered Markdown, images, PDFs, sound files, git diffs. Web links can open in an inline โŒ— viewport. On iPad both land in a side panel beside the pane โ€” the terminal never changes size โ€” or move into a tab. WIDGETS & SHORTCUTS Put a host on your Home Screen โ€” last-known frames, an honest SEEN stamp, SHELL and AGENT keys straight into a connection โ€” or a fleet widget for every host at a glance. Shortcuts and Siri open a shell, show a remote file, or launch an agent in a chosen directory, fresh or inside an existing session. A multiplex:// URL scheme drives automations. MOSH BUILT IN With Pro, switch a host to mosh and the session survives sleep, roaming, and IP changes โ€” a native Swift mosh client, no companion app. CONNECTION STATS A live latency chip on every host rail; Pro opens the full per-host board: round-trips, typing echo, mosh loss and roams, reconnects, data volume. Measured in-session; nothing leaves the device. A REAL TERMINAL xterm-256color emulation, multilingual system-keyboard input, touch and pointer clicks for mouse TUIs, hardware keyboards, live PTY resize, and a menu of everyday tmux (or herdr) commands. Hold CTRL for Key Commands: saved chords the software keyboard cannot press (Shift+Enter, a double Ctrl-C) and one-line text macros, synced everywhere. Pane-clamped selection on long press or double tap. System, Light, and Dark switch the whole chassis, each with its own terminal theme โ€” ten built in; Pro adds an editor down to all 16 ANSI colors. The app speaks English, Traditional Chinese, and Japanese. OPEN SOURCE, PRIVATE BY DESIGN The complete app โ€” terminal engine, mosh client, and all โ€” is open source, Apache 2.0, at github.com/multiplex-term/Multiplex. Read the code that holds your keys, or build it yourself. Hosts, command setups, and secrets sync through iCloud Keychain, end-to-end encrypted. Nothing touches our servers โ€” there are none. No account, no analytics, no tracking. MULTIPLEX PRO One purchase, no subscription: unlimited hosts, mosh, agent notifications, the Connection Stats board, the unmetered command strip, custom themes, and twelve Key Commands. Free includes two hosts, the complete terminal, five Key Commands, and 10 chip taps a day. WHAT YOU NEED A remote host reachable over SSH (password or ed25519/RSA key). The wall and persistent sessions need tmux 1.8+ or herdr 0.7.5+; plain SSH shells need neither. mosh needs mosh-server on the host.
