Overview
Safe Outreach is a web-based LinkedIn extension safety checker. It lets users search an extension by name, Chrome extension ID, or Chrome Web Store URL and compare it to the Active Extension Detection (AED) list found in LinkedIn's own frontend code. The page says the November 2026 snapshot contains 4,934 extension fingerprints, and the checker queries those signatures to show whether a tool appears on LinkedIn's list.
The site explains that LinkedIn's AED list is hardcoded and probed on page loads via chrome-extension://<id>/<file> requests. If the extension is installed for a listed ID, the checker reports it as detected. Safe Outreach also emphasizes that this list is only one signal: LinkedIn combines extension detection, page traces, fingerprint mismatch, and behavior into a scorecard rather than an automatic ban.
Beyond the list lookup, Safe Outreach publishes code teardowns of LinkedIn tools, including data-flow maps that show whether a session stays local or is uploaded to a vendor cloud. It covers 100+ tools in its research and lists 142 extension checks. The site warns that not being on the AED list does not mean an extension is safe, citing tools that inject into the page or upload sessions despite not appearing on the list. Detection applies to Chromium browsers such as Chrome, Edge, Brave, Arc, and Opera.
Key Features
- AED list checker — Search by extension name, ID, or Chrome Web Store URL against LinkedIn's 4,934-ID detection snapshot from November 2026.
- Detection explanation — Shows how LinkedIn probes installed extensions with chrome-extension:// URLs on page load and what a positive result means for an account.
- Code teardown verdicts — Provides line-by-line source-code reviews for LinkedIn tools, with deep dives into where session cookies and data go.
- Session data-flow maps — Reconstructed diagrams label tools as local-scrape, cookie-bridge, or session-upload architectures with risk ratings.
- AED history and stats — Tracks how the detection list grew from 38 entries in 2017 to 6,153 in February 2026, then rotated to 4,934 by November 2026.
- "Not listed" caveat — Explains that absence from the AED list does not clear an extension because another scanner can catch page injection.
- Chromium-focused coverage — Notes that LinkedIn's scan runs in Chrome, Edge, Brave, Arc, and Opera, gated by a userAgent check.

Who It's For
Safe Outreach is for sales, recruiting, growth, and agency teams that use or evaluate LinkedIn automation Chrome extensions and want to reduce account-restriction risk. It is also useful for operators comparing tools such as Waalaxy, Dux-Soup, Octopus CRM, PhantomBuster, lemlist, Aimfox, Kanbox, and Jobin before installing them.
Typical use cases include checking whether a tool is on LinkedIn's AED list, reviewing a code teardown to see whether a session leaves the browser, and understanding why "not detected" is not the same as "safe." The checker is aimed at people who want evidence from LinkedIn's own frontend code and extension source code rather than vendor claims.
