As answered by people managing SecureFollow.app and DynamicDocumentAPI.
SecureFollow.app's answer
SecureFollow is privacy-first by design: it analyzes your Instagram relationships using your official Instagram data export (ZIP) and runs 100% locally in your browser. No login, no password, and no uploads — your files stay on your device. It’s a simple, safe alternative to unfollower tools that require account access or automation.
DynamicDocumentAPI's answer:
It covers the whole path from data to finished document in one API: you design a template in a visual or HTML editor (or send raw HTML, CSS or Markdown), send JSON, and get a PDF or image back. The same service also creates e-invoices (XRechnung, EN 16931, Factur-X / ZUGFeRD) that are validated against the official rules before they are returned, and can embed them in the PDF. Rendering is deterministic: the same template and data always give the same document, laid out by a headless browser, with no AI model generating content. Everything runs in the EU (Germany). It also ships an MCP server, so AI agents like Claude and ChatGPT can render documents directly.
SecureFollow.app's answer
SecureFollow started as a response to a common problem: most “unfollowers” apps require logging in with your Instagram account. We wanted a safer option, so we built a tool that works from the official Instagram data export and runs locally in the browser. The goal is simple: useful insights with zero credential sharing.
DynamicDocumentAPI's answer:
Almost every product eventually needs to produce documents, and most teams end up building their own rendering stack: a headless browser, fonts, page breaks, storage and retries. It works until an invoice splits a table row or a certificate shows the wrong date, and then it becomes a support ticket. We built Dynamic Document API to be that layer for them: templates, rendering and delivery as one service, hosted in Europe, treating pagination, fonts and formatting as engineering problems rather than edge cases. When e-invoicing became mandatory for B2B in Germany, we added validated XRechnung and ZUGFeRD output, and with AI agents producing more paperwork, an MCP server followed.
SecureFollow.app's answer
Many unfollower tools ask for Instagram credentials or rely on automation, which can be risky. SecureFollow avoids that entirely by using the user’s own official export (ZIP) and processing it locally. You get clear results (unfollowers, not-following-back, mutuals) without handing over your account or data.
DynamicDocumentAPI's answer:
Most document APIs do one thing: convert HTML to PDF, or fill templates. Dynamic Document API does both, adds image templates, PDF merging and validated e-invoices, and offers them through a REST API, SDKs for Node and Python, Zapier, Make, n8n and an MCP server for AI agents. Data is processed and stored in the EU only, files come back as signed links that expire, and storing nothing at all is a supported option. Pricing is predictable: one published credit table, the same core features on every paid plan and a spend cap you control. We also publish a render-time benchmark with its method and raw data, so you can check our speed instead of trusting a claim. The free plan includes 50 renders a month without a credit card.
SecureFollow.app's answer
SecureFollow is for Instagram users who want to check unfollowers safely: creators, influencers, community managers, and privacy-conscious users. It’s especially useful for anyone who doesn’t want to trust third‑party apps with their Instagram login.
DynamicDocumentAPI's answer:
Developers and product teams whose software has to send documents: invoices after a payment, certificates after a course, reports, labels and statements. Typical users are SaaS companies, marketplaces, e-commerce and learning platforms. A second group are businesses in Germany and the EU that need compliant e-invoices (XRechnung, ZUGFeRD) for the German B2B e-invoicing mandate and public-sector buyers. No-code builders use it through Zapier, Make and n8n, and teams building AI agents use the MCP server.
SecureFollow.app's answer
SecureFollow is built as a modern web app / PWA using JavaScript/TypeScript and runs entirely client‑side in the browser. It parses the Instagram export (ZIP/JSON) locally and uses browser storage for optional saved history. The site is delivered via a CDN (Cloudflare) for fast global access, with no server-side processing of user exports.
DynamicDocumentAPI's answer:
Rendering runs in Rust workers that drive headless Chromium over the DevTools protocol, with MiniJinja for templates. The API and control plane are built with Django and Django REST Framework, with Celery, PostgreSQL, Valkey and NATS JetStream for queues and events, and S3-compatible object storage for files. PDF/A output is checked with veraPDF and e-invoices with the official KoSIT validator. The dashboard and website are built with Next.js. Everything runs on Kubernetes in data centres in Germany.

DynamicDocumentAPI's answer:
Dynamic Document API is a young product. Our users are mostly developers and small SaaS teams, and we don't name customers without their permission.
