Download questions

Download & install FAQ

Global CDN: Cloudflare + AWS CloudFront. If slow:
1. Try a download manager (multi-threaded)
2. Off-peak hours (weekday evenings 8-10pm)
3. Email support@seocrafttools.com for an offline mirror link
Control Panel → Programs and Features → uninstall the old version (all versions from V1.0 onwards), then reinstall the latest. Default install path is %LOCALAPPDATA%\SeoTools.
V3.3.1 supports Windows 10/11 only. Mac (Apple Silicon) and Linux are on the roadmap — Beta expected in 2026 Q4. Join the Beta waitlist.
Because the app launches Playwright browser, Python sandbox, and loads AI models, some antivirus may flag it. Rest assured, we are open source and transparent — no malicious code. We recommend: add the install folder to your AV whitelist, or use Windows Defender's "App & browser control" to allow it.
