Sputnik

Free

Nothing opened on 20 Oct 2026 printed a price for Sputnik. The Chrome Web Store page and the Firefox add-on page both present it as an extension you add, with no checkout. The SPDX field on the GitHub API was NOASSERTION. LICENSE.md is a copy of the Mozilla Public License, Version 2.0, and package.json says MPL-2.0. The Firefox page's license line is Mozilla Public License 2.0. Those license sentences are not a fee. There is no hosted plan to upgrade into. The store's 10,000 users and the Firefox page's 680 users are install counts on those pages, not a price and not a rating. No donation badge was required to describe the extension.

The README says you highlight an artifact or right-click a link, then pick an OSINT tool. For some tools the extension opens a result. For tools that need a captcha, it copies the artifact and opens the submission page. The README groups the menu by IP, domain, file hash, and URL. Names already in this directory, including Shodan, Censys, VirusTotal, and urlscan, appear in those lists. The lists also name sites this directory does not review. A menu entry is a link. The other site's page is the result. This review did not install the extension and did not open a pivot.

• SPDX is NOASSERTION. The GitHub license field was NOASSERTION. LICENSE.md, package.json, and the Firefox page name MPL-2.0.
• 1.25 and 1.32. Chrome's manifest and store listing said 1.25. Firefox's manifest and add-on page said 1.32. package.json said 1.0.0.
• The rating is not the build. 5.0 from 15 ratings is the Chrome Web Store rating. The version line under Details was 1.25.

1. 1

   Install the build whose version you mean, and write Chrome 1.25 and Firefox 1.32 as separate facts.

2. 2

   Use a pivot as a link to another tool. Read that tool's page before you brief it.

3. 3

   Do not treat the store rating as a release number.

• An install note is about to say Sputnik 5.0. On the Chrome Web Store page opened 20 Oct 2026, 5.0 is the rating from 15 ratings, and the details block says version 1.25, updated March 2, 2026, with 10,000 users. The Firefox add-on page said version 1.32, 680 users, and a rating of 5 from 4 reviews. package.json said 1.0.0. Write the build and the rating as different sentences.
• The license is about to be smoothed into one line. The GitHub SPDX field was NOASSERTION. LICENSE.md and package.json say MPL-2.0, and the Firefox page says Mozilla Public License 2.0. The answer uses the SPDX field and still quotes the file. No price was printed on either store page.
• A right-click is about to be briefed as the pivot result. The README says the menu opens another OSINT site, or copies the artifact when that site needs a captcha. This review did not install the extension. Shodan, Censys, VirusTotal, and urlscan are examples of names in the menu, not results this listing retrieved.

Hard cases

The case where the first result is easy to over-read.
