About
Fillo is infrastructure for product forms that lets teams build forms directly into their own applications without rebuilding validation, uploads, responses, versions, and delivery for every new workflow. Instead of embedding an iframe, it renders accessible controls inside the product so the existing route, components, CSS, fonts, and design system stay in control. Developers can start with Fillo’s default controls, replace individual fields, or use headless hooks for fully custom layouts across React, Vue, Svelte, Astro, or plain browser apps. Each response can carry hidden product context such as the account, user, plan, page, or application state without asking the customer to enter that information manually. File uploads can go browser-direct to connected Google Drive, Box, Amazon S3, or Cloudflare R2 while durable file references stay attached to the response. Teams can review answers, files, context, and delivery state together, then export responses or send them into systems.

About
SurveyJS is an embeddable, self-hosted, white-label form builder for teams building custom forms, surveys, questionnaires, and other data collection tools inside web applications. It runs entirely on the client and is fully compatible with all modern JavaScript frameworks, including React, Angular, and Vue. SurveyJS integrates with any backend, giving you full control over data, security, user access, deployment, and business logic. Instead of hardcoding forms, you can empower non-technical users to generate and edit JSON schema-based form configurations through a drag-and-drop form builder.
Create dynamic forms with custom conditional logic, validation, multilingual support, PDF export, and analytics. Ideal for SaaS, enterprise software, HR, healthcare, fintech, and other regulated industries, SurveyJS helps teams reduce engineering effort, standardize data collection, maintain full control over data, and deliver unlimited forms that match their brand and feel native to users.
