Looking for an IronPDF alternative? Here's an honest comparison. IronPDF is a .NET library that embeds Chromium and renders HTML to PDF on your own servers, sold as perpetual licenses per developer, location and project. Shotmint is an HTTP API: you send a URL or raw HTML from C# (or any language) and get a PDF back, paid per render with prepaid credits and nothing to install.
| Model | Price | Free tier | Unused volume | |
|---|---|---|---|---|
| IronPDF | Perpetual license per developer, location and project | Lite $999 (1 developer, 1 location, 1 project) · Plus $1,499 (3) · Professional $2,399 (10; list price $2,999) · Unlimited $4,799 (list $5,999). One year of updates and support included, then renewed yearly. Royalty-free redistribution (SaaS/OEM) costs extra below Unlimited | 30-day trial key, full features | No per-document limit on licensed deployments |
| Shotmint | Prepaid credits, no subscription | €5 / 2,000 · €19 / 10,000 · €59 / 50,000 (one-time) | 25 free renders a month, no signup | Never expire |

IronPDF runs inside your own process, so documents never leave your servers and there is no network round trip or per-document cost: once licensed, a million PDFs cost the same as ten. That matters for air-gapped or strict data-residency setups and for very high volumes (17 Shotmint Scale packs, 850,000 renders, cost €1,003). It is also a full PDF toolkit, not just a renderer: its site lists merging, watermarks, digital signatures and security, with a C# API, support for .NET 10 down to .NET Framework 4.6.2, Windows, macOS and Linux, and a 30-day trial with no watermark. If you need offline rendering or heavy PDF manipulation in .NET, IronPDF is the better fit.
You render HTML or URLs to PDF at a normal volume and don't want a per-developer license, a 100 MB native dependency or a Chromium process in your app. The Linux engine package alone, IronPdf.Native.Chrome.Linux 2026.10.6, is a 109 MB download from NuGet (checked 22 October 2026), and it runs a browser inside your container. With Shotmint, 1,000 PDFs a month for a year cost €24 (one €19 pack and one €5 pack), and 3,000 a month cost €59 (one 50,000-render Scale pack); the cheapest IronPDF license is $999 for one developer and one project, and adding developers or projects moves you up a tier. Credits never expire, failed renders are free, and the same key works from every project, language and machine, with no seat count. POST /v1/pdf takes a URL or raw HTML with A3/A4/A5/Letter/Legal/Tabloid, landscape, margins, scale, backgrounds, header and footer templates and page numbers; the same credits cover PNG/JPEG/WebP screenshots. The C# HTML to PDF guide has a tested HttpClient example, and a free key with 25 renders a month takes one request, with no signup. We don't edit, sign or merge existing PDFs through the API (our free merge and sign tools run in the browser) and we can't run offline, so for those pick IronPDF.
GET /v1/screenshot: PNG, JPEG or WebP screenshots of any URL, with full-page capture, custom viewport, retina scale, a single-element selector, dark mode, transparent backgrounds (omit_background), ad and cookie-banner blocking (block_ads), and hide_selectors.POST /v1/pdf: PDFs from a URL or raw HTML, with format, landscape, margins, backgrounds, header and footer templates, and page numbers.GET /v1/content: the main content of any page or PDF link as Markdown, plain text or clean HTML, with title, author and date, for LLMs and RAG.GET /v1/og: 1200×630 Open Graph cards from a title and subtitle, with signed public URLs you can put straight in an og:image tag.X-Credits-Remaining header.Shotmint is a new, small service. It has small Node and Python SDKs and integration guides, but no enterprise plans, SLA or team accounts yet (measured uptime and render times are public on /status). If you need those, IronPDF may suit you better. If you want an API key in 10 seconds and to pay only for what you use, try it.

No signup, no card; the free key refills on the 1st of every month. If you need more, buy credits once: €5 for 2,000, €19 for 10,000, €59 for 50,000. They never expire, and they stack on top of the 25 free renders a month, which every key keeps. From a script, an AI agent, Make or Zapier, POST /v1/keys/free (no body) returns a key as JSON (openapi.json, no-code recipes).
