Web
IPKit

The homepage shows your current IPv4/IPv6 along with country, region, city, timezone, ASN, ISP, and VPN/proxy/Tor/cloud signals; you can also enter any IP to look it up. The same JSON record is available from the command line: curl https://ipkit.dev or curl https://ipkit.dev/8.8.8.8. Requests are handled at Cloudflare's edge and full visitor IPs aren't stored app-side. The UI supports 10 languages. Free, no sign-up.
Sitelemetry
Web
Sitelemetry
Sitelemetry brings website audit evidence, prioritized findings and remediation guidance into compatible AI clients through a hosted OAuth MCP connection. It does not change the target website. The free account includes limited security checks; technical SEO, AI visibility, accessibility, performance and integrations require a paid plan. Several checks read static HTML rather than browser-rendered pages. Protected security modules and full six-area audits require target verification. A separate free, no-account Launch Readiness snapshot covers eight passive public-signal groups. Sitelemetry is not a penetration test or security certification.

Estimates are not quotes; actual charges depend on usage, vendor pricing and applicable taxes.

Worktree
windows
Worktree
Worktree is a desktop workspace for developers and small software teams building with AI coding agents. It brings teammates and agents into one shared project, with separate threads for different tasks. Agents can share context, send messages across threads, and coordinate changes while teammates follow progress and steer the work together. Project owners control who can read files, work with agents, edit files, and manage sharing. The goal is to reduce the manual work of relaying updates between people and agent conversations. Worktree is currently available as a free alpha for Windows. Users bring their own AI provider connection; model usage follows the provider's pricing. We are looking for developers and teams to try Worktree on a real project and share feedback on what is useful, confusing, or missing. Learn more and try it: https://tryworktree.com
