run402 vs fitter

run402: run402 is a backend platform providing comprehensive services for AI agents, including a full Postgres database, REST API, user authentication, content-addressed file storage, serverless functions, and image generation. It enables agents to autonomously build and deploy full-stack applications through various interfaces like SDKs, CLIs, and MCP tools.; fitter: Fitter is a declarative tool that transforms any website or API into structured JSON, eliminating the need for brittle scraping scripts. It's designed for AI agents, allowing Large Language Models to author, validate, and execute data extraction pipelines locally, on demand.

Features

run402 logorun402
01Full-stack backend services (Postgres, REST API, Auth, Storage, Static Sites, Serverless Functions, Image Generation).
02Multi-interface control via TypeScript SDK, CLI, MCP tools, OpenClaw skill, and Astro integration.
03Autonomous, x402 USDC-based payment for agent-driven operations and deployments.
04Declarative deployment with manifest files and integrated CI/CD for GitHub Actions.
05Built-in RLS-aware database clients and helpers for in-function logic (e.g., `db()`, `adminDb()`, `auth`, `email`, `ai`).
fitter logofitter
01Declarative & Auditable Configuration: AI agents produce readable, savable, and re-runnable configurations instead of throwaway code.
02Local-first Data Fetching: All data fetching occurs on the user's machine, eliminating reliance on third-party scraping APIs or per-request billing.
03Batteries Included: Provides a comprehensive set of tools including HTTP client, headless browser (Playwright/Chromium/Docker), various parsers (JSON, HTML, XML, XPath), pagination, caching, and rate-limiting.
04Multiple Usage Modes: Can be used as an MCP server for AI clients, an AI-powered CLI agent, a local CLI, an embeddable Go library, or a long-running service.
05LLM Integration via MCP: Exposes a Model Context Protocol (MCP) server, enabling Claude Code, Claude Desktop, and other MCP clients to author and run scraping pipelines.
