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

Flue is an open agent framework for building durable AI agents with a programmable TypeScript harness. Created by the team behind Astro, it uses a React-like hooks API to compose agent behavior, persistent state, lifecycle events, models, tools, sandboxes, subagents, skills, and MCP servers in code. Agents are stateful and addressable over HTTP, keep context across conversations and events, and can change capabilities as work progresses. Flue records every session in a durable stream, so accepted work survives crashes, restarts, and deploys; interrupted sessions resume automatically and clients reconnect without starting over. Developers can run agents locally, in CI, from their own backend, or orchestrate them with systems such as Cloudflare Workflows and Inngest. Secure sandboxes let agents run commands, edit files, and do real work, while tools connect them to APIs and data. Flue is powered by Pi and supports different LLM providers, allowing teams to choose the models they want.
