Screaming Frog alternatives

12 tools that do a similar job, and what makes each one different.

What Screaming Frog is

The Screaming Frog SEO Spider is a desktop crawler that fetches a site's URLs and reports technical SEO problems. It runs on Windows, macOS and Linux, and checks for more than 300 distinct SEO issues. The crawler can render JavaScript, so client rendered pages are crawled as a browser would see them. Custom extraction pulls arbitrary data out of pages using XPath, CSS Path or regular expressions, spelling and grammar checking covers more than 25 languages, and crawls can be scheduled to run automatically. The crawler also connects to Google Analytics, Google Search Console and PageSpeed Insights to pull their data in alongside the crawl data. Because the crawl runs on your own machine, that machine sets the ceiling. The application starts in database storage mode with 2GB of RAM allocated, which is generally sufficient for crawls under 200,000 URLs. Memory storage mode keeps the crawl in RAM instead and typically handles 10,000 to 100,000 URLs at the same 2GB default allocation. Crawling more than a million URLs is recommended on an SSD with 16GB of RAM or more, and the stated minimum is a 64 bit operating system with at least 4GB of RAM available. The free version stops each crawl at 500 URLs. A paid licence makes the crawl limit unlimited, bounded only by the machine's memory and disk, and costs 199 pounds per year. Licences are per user, so two people need two separate licences, and each licence runs for one year and must be renewed to continue working. Buying in volume lowers the rate to 189 pounds each for 5 to 9 licences, 179 pounds for 10 to 19 and 169 pounds for 20 or more. Prices can be displayed in pounds, US dollars or euros. The Log File Analyser is a separate product that ingests server logs, verifies search engine bots and reports which URLs those bots requested. It reads Apache logs, the W3C Extended Log File Format and the Amazon Elastic Load Balancing custom log format. The free version is limited to 1,000 log events and one project at a time, and a licence is listed at $139 per year.

A broad suite covering keyword research, rank tracking, competitor analysis, site audits, backlinks, advertising research and social. The breadth is the selling point and the drawback: teams that use most of it get real value, and teams that want one job done well often find something narrower cheaper. Its competitor teardowns are the feature people cite most.

Freemium

Technical SEO auditing that explains why each issue matters and what to do about it, rather than emitting a list of flags and leaving prioritisation to you. Crawls render JavaScript, and reports are readable enough to hand to a client. The educational framing is the differentiator; it is often run alongside a raw crawler rather than instead of one.

Paid

The backlink index that most SEO arguments end up being settled with, alongside keyword research, rank tracking, site auditing and content exploration. The crawler is among the largest outside the search engines, which is why its link data is treated as a reference point. Expensive, with no free tier of consequence, and priced as a professional tool.

Paid

Builds content briefs and scores drafts against what already ranks for a term, headings, length, entities and related terms drawn from the current top results. Useful as a check on a writer's instincts and dangerous as a substitute for them: optimising to a score produces text that reads like it was optimised to a score.

Paid

The ecosystem around Lottie, the format that ships vector animation as JSON. Animations stay sharp at any size, weigh a fraction of a GIF or video, and can be recoloured or controlled at runtime. The platform hosts a large library, converts from After Effects, and provides players for web and mobile.

Freemium

A terminal that treats each command and its output as a block you can navigate, copy and share, rather than an endless scroll. Input behaves like a text editor, history is searchable, and an assistant can read a failing command and suggest the fix. Workflows save parameterised commands for a team. Some of it requires an account, which is the objection people raise most.

Freemium

Generates mobile and web apps from a table your team already maintains. Rows become screens, columns become fields, and the result is installable and works offline. Best for internal tools (inventory, inspections, field data, directories), where the alternative is a spreadsheet somebody edits on a phone.

Freemium

Daily product launches with a badge and a backlink, run transparently, the ranking rules and the code are public, which is unusual in this category. Free and premium submission paths, with the paid one skipping the queue. Positioned as an open alternative to the closed boards, and worth watching for that reason as much as the traffic.

Freemium

Full web applications without writing code: a database, workflow logic, an editor for the interface, and a plugin ecosystem for the rest. Genuinely capable (real businesses run on it), and it is a platform commitment rather than a prototype tool. Performance and cost at scale are the recurring criticisms.

Freemium

VS Code rebuilt around a model that can see the whole repository. Beyond autocomplete it edits across files from an instruction, answers questions about unfamiliar code, and applies a diff you review before it lands. Keybindings and extensions carry over from VS Code, so switching costs an afternoon. The multi-file edit is the feature people stay for.

Freemium

Event analytics for questions that begin with 'how many users who'. Funnels, retention curves, cohorts and flows are the core, built on events with properties rather than pageviews. Strong at behavioural questions and weaker at the simple traffic reporting a marketing team wants, which is why it often sits beside a web analytics tool.

Freemium

Deploys a frontend by pushing to a branch, with a preview URL for every pull request, the workflow most React teams now expect by default. Built by the maintainers of Next.js, which it supports first and best. Edge functions, analytics and image optimisation are included. Costs are predictable until traffic is not, and bandwidth is the line to watch.
