Switching from Screaming Frog to Seodisias: A Practical Migration Guide
If you are reading this, you probably already know Screaming Frog well. You have your crawl configurations memorized, you know which reports you open first, and you are not here because the tool is bad. Most people who look to switch do it for one practical reason: the free version stops at 500 URLs, or the yearly license stopped making sense for how often they actually crawl.
Seodisias is a natural next step precisely because it does not ask you to change how you work. It is a free desktop SEO crawler that runs locally on your machine, with no URL cap and no subscription. This guide walks through the move the way an actual migration goes: what feels familiar, what you gain, and how to run your first crawl.
If you are still comparing options rather than committing, the broader Screaming Frog alternatives guide and the best free SEO crawler comparison put Seodisias next to the other tools first.
What Stays the Same
The biggest worry when leaving a tool you trust is relearning everything. You will not have to.
Seodisias is a desktop application, just like Screaming Frog. It runs on your own machine, and your crawl data never leaves it. That means the same privacy you are used to: no account, no upload, nothing sent to someone else’s server. If working locally was one of the reasons you liked Screaming Frog, that reason carries over completely.
You also keep control of the crawl itself. Before a crawl you set the depth, concurrency, request rate, user agent, whether to respect robots.txt, and whether to render JavaScript. These are the same levers you already reach for, so configuring your first crawl will feel like sitting down at a familiar desk in a different room.
What You Gain
The move is not just lateral. A few things get better right away.
No URL limit. This is the headline. Screaming Frog’s free tier stops at 500 URLs, which is the first few minutes of a real crawl on any ecommerce store, publisher, or site with faceted navigation. Seodisias has no cap on the free version, so a large site does not force a purchase decision on you. If crawl budget on a big site is your real concern, the ecommerce crawl budget guide goes deeper.
Free, with no yearly license. There is no subscription and no per-seat cost. For a freelancer who audits a couple of sites a quarter, or a developer who only needs a deep crawl during a site move, that pricing shape fits far better than an annual license.
AI-ready checks built in. Alongside the classic technical audit, Seodisias checks things Screaming Frog was never built for: an llms.txt check, JSON-LD and Schema.org validation, and robots.txt analysis. As search shifts toward AI answer engines, having these in the same crawl is genuinely useful.
A link graph you can see. Internal and external links are not just rows in a table; Seodisias draws an interactive force-directed link graph so you can actually see how authority flows through the site.
Step by Step: Your First Crawl
Here is the practical path from download to first report.
1. Download for your platform
Seodisias is cross-platform. There are builds for Windows, macOS (both Apple Silicon and Intel), and Linux, distributed through GitHub Releases. You can download Seodisias for free with no signup and no email wall. Install it the same way you install any desktop app.
2. Set up your first crawl
Enter your start URL and open the crawl settings. You will recognize every option: maximum depth, concurrency, a request rate limit to stay polite, a custom user agent, respect-robots toggle, and JavaScript rendering for single-page apps. If you tend to run a slow, shallow crawl first to check scope before going deep, do exactly that here.
3. Find your familiar reports
After the crawl, the reports you open first in Screaming Frog are all here: HTTP status codes and 4xx/5xx errors, redirect chains, missing and duplicate titles and meta descriptions, heading structure, canonical tags, hreflang, and meta robots directives. There are more than thirty technical checks, plus SSL, mixed content, compression, and caching headers. Nothing you rely on for a technical audit is missing.
4. Export and share
When you are ready to hand results to a client or a developer, Seodisias exports a PDF report and a Markdown report (including an AI-ready export). If you crawl the same site again later, the progress report compares two crawls and shows what changed, which is exactly what you want during a migration or a fix cycle: a clean before-and-after.
An Honest Note on What Is Different
Honest comparisons help more than loyalty does, so here is where Screaming Frog still has an edge.
Seodisias does not import a Screaming Frog configuration file or a saved URL list, so you set your crawl up fresh the first time. It also does not run scheduled or unattended crawls on its own; you start each crawl manually. If your workflow depends on nightly automated runs, that is worth knowing before you switch. For a team weighing where a crawler should run at all, the cloud vs desktop crawler breakdown is the honest framing.
For most people, though, none of that outweighs the simple math: a desktop crawler you already know how to drive, with no URL cap and no yearly bill, that keeps your data on your own machine.
Ready to Crawl
Migration sounds heavier than it is. Download Seodisias, point it at a site you know well, and run the same audit you would have run in Screaming Frog. You will land on familiar ground within the first crawl, minus the 500 URL wall. When you are ready, start crawling for free with Seodisias.
