Formstack Testing on Autopilot
Meet Topoff, the Chrome extension that automates your form data entry. Record complex sessions, save them locally, and replay them in seconds.
Your new testing workflow in 3 steps.
Record
Click the floating Topoff button and fill out your form normally. We quietly capture every text input, dropdown selection, and file upload in the background.
Save
Name your session to build a library of reusable test cases like "Happy Path," "Validation Error," or "Complex Logic."
Replay
Need to test again? Just hit Play. Topoff fills the entire form in seconds, handling multi-page navigation automatically.
Built specifically for Formstack.
API-Native Intelligence
Unlike generic autofill extensions that break if you change a field label, Topoff talks directly to the Formstack API. It understands your form's structure, hidden fields, and logic.
Multi-Page Mastery
Have a 10-page survey? Topoff handles pagination automatically, filling in all pages regardless of visability or conditional logic.
100% Local & Private
Your data is your business. Topoff stores all session data locally in your browser. Nothing is ever sent to a cloud server.
File Upload Support
Testing file attachments is usually a manual nightmare. Topoff records your file uploads and re-uploads them instantly during replay.
Who needs Topoff?
QA Teams: Run regression tests in seconds instead of hours.
Form Developers: Test complex calculation logic without re-typing data 50 times.
Agencies: Perform flawless live demos for clients without the risk of typos.
