Topoff - Formstack Forms Filler by Runway Hero

About

Stop wasting time manually filling out forms during testing.

Topoff is the essential utility for Formstack power users, developers, and QA teams. Built specifically for the Formstack v4 API, Topoff lets you record your form-filling sessions once and replay them instantly, saving you hours of repetitive data entry.

Whether you're debugging complex conditional logic, verifying multi-page workflows, or testing integrations, Topoff handles the heavy lifting so you can focus on the results.

Why Topoff?

Built for Formstack: Unlike generic autofill tools that break when brittle underlying forms change, Topoff communicates directly with the Formstack Live Forms API. It understands your form's logic, hidden fields, and validation rules.

Record & Replay: Simply fill out your form once to create a "Session". Replay that session anytime with a single click.

Multi-Page Mastery: Seamlessly handles multi-page forms, automatically navigating through steps as it fills.

File Uploads: Records and replays file uploads so you can even test attachment requirements.
Secure by Design: Your data never leaves your machine. All form data is stored locally in your browser.

Key Features

Smart Recording: Captures every keystroke, selection, and file upload.
Instant Replay: Fill entire forms in seconds with 100% accuracy.

Session Management: Organize multiple test cases (e.g., "Happy Path", "Error State", "Complex Logic") for the same form.

Privacy Control: Domain and field deny-lists ensure you never record sensitive PII by accident.
Team Friendly: Export and import sessions to share test cases with your team (Pro feature).

Privacy & Security: Topoff operates entirely locally. No data is sent to cloud servers. Your recorded sessions are stored securely within your browser instance.

Free vs Pro

Free: Get started with up to 3 saved sessions across 2 forms. Perfect for quick testing.
Pro: Upgrade for unlimited sessions, unlimited forms, and the ability to import/export sessions for team collaboration.
Get Topoff today and put your form testing on autopilot!
