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

Formgong is a hosted backend for website forms. Developers keep their own HTML form and send submissions to a Formgong endpoint, where entries are stored in an inbox and can be delivered by email, Telegram or webhooks. It supports forwarding to Slack and Discord through incoming webhooks, and saving accepted submissions as rows in Google Sheets. Spam controls include a honeypot, server-side filters and optional Cloudflare Turnstile. The service is aimed at developers, freelancers, agencies and small businesses who want to collect form submissions from static, WordPress or AI-built websites without maintaining a form-processing server. Plans include submission limits, retention periods and delivery features; a free plan is available.
