Companion Browser Extension

The HiringTrends Companionis a Chrome side-panel extension that reads the job you're viewing on supported job boards and surfaces HiringTrends context next to it: salary benchmarks for the role, stack pulse for the tech mentioned, and company context. It's designed to give you market context inline while you browse — no copy-pasting between tabs.

What it does

  • Salary benchmarks — percentile ranges for the role and level on the page, pulled from our benchmarks.
  • Stack pulse — momentum on each technology the posting mentions (see Hiring Radar).
  • Company context — recent hiring activity and any signals we have about the company that posted the job.

Supported sites

The Companion activates on these boards:

  • LinkedIn
  • Indeed
  • Dice
  • Wellfound
  • Levels.fyi
  • RemoteOK
  • We Work Remotely

The full list lives in the extension's manifest (host_permissions) and is the source of truth — if a site is here, it's supported; if it isn't, the panel stays empty on that page.

Install (preview)

The Companion is currently in preview / sideload distribution. The Chrome Web Store listing is coming. To install the preview build:

  1. Get the unpacked build directory (build/chrome-mv3-prod/ from a Companion build) from your invite.
  2. Open chrome://extensions and toggle Developer mode on (top right).
  3. Click Load unpacked and pick the chrome-mv3-prod directory.
  4. Pin the Companion in the Chrome toolbar so you can open the side panel quickly.

Using the side panel

Open any job on a supported site, click the Companion icon (or open the Chrome side panel and pick HiringTrends), and the panel hydrates from the current page. As you navigate between roles on the same board the panel updates in place — no page reload required.

The Companion uses the same HiringTrends account you signed in to on the web — sign in at hiringtrends.dev and the panel will pick up your session.

Privacy

The Companion only reads the active job page when you open the panel — it does not background-scrape pages you visit. Telemetry is the same as the web app (PostHog, anonymized). Your HiringTrends session cookie is the only credential it sends back.

Troubleshooting

  • Panel doesn't open— confirm you're on one of the supported sites above and that the extension is enabled in chrome://extensions.
  • Salary section is empty — the board hides comp on some postings; the Companion only shows benchmarks when it can identify role + level from the page.
  • Signed-out state — open hiringtrends.dev/auth/sign-in, finish the magic-link flow, then reopen the panel.

Other browser extensions in the HiringTrends ecosystem (board parsers for Levels.fyi, Indeed, etc.) are documented separately — this article covers the subscriber-facing Companion only.
