Add a company
Open issues labelled company-request are companies waiting to be added — most resolve in five minutes with a coding agent.
wsis a tool for your coding agent, not for you directly. Set up Claude Code, Cursor, or another agent first; the agent installs and runs the CLI itself.
pip install jobseek-crawler-setup
Pick an issue, then hand your agent this prompt:
Run
ws task --issue <NUMBER>and follow the printed instructions.
ws walks the agent through fetching the issue, finding the career page, choosing the right monitor and scraper from the 40 available, validating the result, and opening a PR. Choosing the right combination by hand is tedious — getting it wrong silently misses postings, which is why the workflow is structured this way.
No open issues for the company you want? Request it. Anyone can.
Agent environment: git, gh (authenticated), Python 3.12+, web access.
Run your own
Clone, point at your Postgres + Redis + Typesense, run the crawler and the Next.js app:
git clone https://github.com/colophon-group/jobseek
cd jobseek
# Crawler (Python 3.12+, uv)
cd apps/crawler
uv sync
cp .env.example .env.local # DATABASE_URL, REDIS_URL, TYPESENSE_*
uv run crawler sync # CSV → Postgres + Redis + Typesense
uv run crawler run # start a worker
# Web app (Node 20+, pnpm)
cd ../web
pnpm install
pnpm db:migrate
pnpm dev # http://localhost:3000
