RadarMakers Tools is a free collection of browser utilities for launch checks: preview page metadata and social cards, build UTM links, and generate favicon packages.
RadarMakers Tools groups eight free utilities for the practical checks around a product or content launch. The collection includes a meta tag preview, social card preview, bulk UTM link builder, launch date planner, screenshot mockup generator, favicon package generator, image optimizer, and changelog generator.
The tools are deliberately small and focused. Six are presented by RadarMakers as running in the browser without an account; we did not audit network traffic or storage. The meta tag and social card checkers are different: you give them a public URL and their server fetches that page so it can inspect the tags.
In our November 14, 2026 trial, the meta tag checker successfully fetched a published Freewares article and reported its title length, description length, canonical URL, and missing-tag status. The social card checker flagged two dated observations from that page: no og:url tag, and different files for og:image and twitter:image. These were trial observations from that page on that date, not a guarantee about every page or network renderer.
The bulk UTM builder generated four tracked links from one fictional destination and four selected channels, and offered copy buttons plus a CSV campaign sheet. A share-result option was present, but we did not exercise it, so its mechanism is unverified. RadarMakers says the UTM builder runs in the browser; our run had no account prompt, but that does not verify transmission or retention.
The favicon package builder accepted our selected PNG, showed true-size icon previews, and offered a ZIP package. We did not download or inspect the package. We did not test the launch date planner, screenshot mockup generator, image optimizer, or changelog generator.
RadarMakers Tools is best treated as a handy shelf of launch-day utilities, not a full SEO audit, analytics platform, or design tool.
Fetches a public URL and reports title, description, canonical URL, redirects, and missing-tag problems.
Checks Open Graph and Twitter card tags for a public URL and warns about missing or inconsistent fields.
RadarMakers says this tool builds channel-specific campaign links in the browser, with editable source and medium values plus CSV export; transmission and retention were not audited.
Shows true-size previews for a chosen image and offers a ZIP download. The page advertises browser, app and manifest icons; package contents were not tested.
Yes. The resources page presents the tools as free, and our November 14, 2026 trial did not require an account.
Six tools are presented as running in the browser. The meta tag and social card checkers send the submitted public URL to the RadarMakers server so it can fetch and inspect the page.
No. It is a small set of launch-day checks and generators. Its previews are useful diagnostics, not ranking predictions or a full audit.
