AgenTTY vs Paytools

AgenTTY is a fast, Ghostty-based SSH client for iPhone, purpose-built for power users of agentic AI coding TUIs such as Codex CLI and Claude Code. What makes AgenTTY different from a typical iOS SSH client is that it is built around the workflows power users actually care about when running long-lived coding-agent sessions from a phone. FEATURES - Native iOS notifications when work finishes or an agent needs input - Paste screenshots and images directly into supported workflows from your phone - Persistent tmux sessions with quick reconnect - Long-press the spacebar for a fast shell quick switcher - Live folder and git-branch context for every shell - A custom keyboard built for terminal work, with familiar shortcuts and modifier slide-chords - Fast dictation for hands-free prompting on the go, with 10 minutes a month during the trial and 120 minutes a month with lifetime access BUILT FOR LONG-RUNNING SESSIONS AgenTTY is especially good for Codex, Claude Code, tmux, and similar terminal-native AI workflows. Keep work alive in persistent shells, jump back in when an agent needs attention, and move quickly between sessions while you are away from your desk. NATIVE PERFORMANCE Built on an ultra-fast Ghostty core, AgenTTY delivers native-feeling performance and smooth terminal rendering on iPhone, even during heavy output and real CLI use. EASY HOST SETUP Run one `npx` helper command on the host, then scan its QR code or enter the short code in the app. AgenTTY reuses or creates a device SSH key automatically, keeps the private key local on your iPhone, and finishes the setup for you. REAL SSH ON IPHONE Even if you do not use AI coding agents at all, AgenTTY still stands on its own as a serious SSH client. Connect to your own machines with public-key authentication, host-key verification, persistent sessions, and a terminal that feels fast, responsive, and native on iPhone. SECURITY BY DEFAULT Generate Ed25519 keys on-device. Private keys stay in the iOS Keychain. Host keys are pinned with trust-on-first-use protection. AgenTTY includes 5 hours of free usage. After the trial, a one-time in-app purchase unlocks lifetime access. AgenTTY is an independent app and is not affiliated with OpenAI or Anthropic.

Paytools is an offline payment-engineering workbench for developers, QA engineers, integrators, students, and fintech teams. Decode and inspect common payment-message structures, explore field definitions, convert technical data, and keep essential payment references close at hand. Processing happens locally on your device, so pasted messages and imported files are not uploaded to a server. PAYMENT TOOLS • Inspect ISO 8583 MTIs, bitmaps, and present data elements • Decode and build primary and secondary bitmaps • Parse BER-TLV data and identify common EMV tags • Recognize SWIFT MT blocks and ISO 20022 XML messages • Convert between HEX, ASCII, decimal, binary, and packed BCD • Validate synthetic card numbers with the Luhn algorithm • Compose synthetic Track 2 and ISO-0 PIN-block test data • Use development utilities for XOR and DES odd parity KNOWLEDGE LIBRARY • Search all 128 ISO 8583 data elements • Learn ISO 8583:1987, 1993, and 2003 MTI concepts • Follow authorization from merchant to acquirer, scheme, and issuer • Understand STIP, advice, reversal, clearing, and settlement flows • Review ISO 20022 message families and validation concepts • Study EMV transaction and cryptogram terminology CODES AND FIELDS Search operational response-code references for common ISO profiles, Visa, Mastercard, UnionPay/UPI, 3-D Secure, and gateway HTTP outcomes. Open any ISO field for its purpose, format, and implementation notes, including an expanded guide to DE22 POS Entry Mode. PRIVATE BY DESIGN Paytools has no account requirement and no cloud processing. Use synthetic or appropriately masked test data. Production payment formats and code meanings can vary by network, region, product, and specification release. Paytools is an independent educational and development utility. It is not affiliated with or endorsed by any payment network. Formal certification and production processing require the current authorized specifications, test packs, approved cryptographic systems, and applicable security controls.
