mega-scraping script to retrieve 600k+ teachers and ranking them based on hacker compatibility. goes from a school's website -> all teachers.rs.

to get started:

git clone this repo>gt; schoolyank

cd schoolyank
bun install
python3 -m pip install -r requirements.txt
browser-use install
cp .env.example .env
bun index.ts --preflight
bun index.tsdex.ts

first run launches an interactive setup wizard: you paste an openrouter key, pick a model, optionally let it spin up an exa account in a disposable browser, then it drops the keys into .env and kicks off the scrape.

what it does:

• checks for apptegy/finalsite shortcuts first (hasura + thrillshare) before spending tokens on the agent
• spins up the local browser-use runner with a structured prompt to crawl staff directories, tabs, filters, pdf links, whatever it takes
• normalizes the agent output (name parsing, email cleanup, dedupe, role scrub, email pattern inference) without dropping non-stem teachers anymore
• resolves the school in the urban institute nces api for verified addresses + phone numbers and logs why if the match fails
• pings dns mx + smtp rcpt to for every email; nukes addresses the server rejects, keeps inconclusive ones untouched
• writes clean csvs to output/ and, in batch mode, a merged output/all.csv
• pushes rows into postgres when DATABASE_URL is set so downstream jobs can keep going even if the cli dies
• streams the play-by-play into slack if SLACK_BOT_TOKEN + SLACK_CHANNEL_ID show up so you can watch the chaos from your phone

interactive mode (bun index.ts) is the guided flow: asks for one url and prints output.

• --url https://example.com scrape one site with no prompts (repeatable)
• bare positional urls work too: bun index.ts https://a.edu https://b.org
• --urls-file urls.txt load one url per line (lines starting with # ignored)
• shorthand @schools_with_staff_urls.csv is the same as --schools-csv
• --output path.csv choose the filename when you pass exactly one url
• --merged-output batch.csv override the merged csv path (default output/all.csv)
• --concurrency N / -j N adjust parallel browsers (default 6); --max doubles cores up to SCHOOLYANK_MAX_CONCURRENCY
• --force re-scrape even if the csv already exists or another worker claimed it
• --interactive force the cute cli even when you provided urls
• --debug firehose every agent/nces/email log line to stderr
• --preflight run environment + dependency checks and exit (same as bun index.ts --preflight)
• every batch run writes progress to output/status.csv (set STATUS_CSV_PATH to move it)

minimal requirement: an OpenRouter key.

• OPENROUTER_API_KEY (required) + optionally AI_MODEL, AI_BASE_URL
• EXA_API_KEY (optional) powers the ranking/enrichment scripts; the main scrape currently runs without it and falls back to DDG when those scripts need web search
• SLACK_BOT_TOKEN, SLACK_CHANNEL_ID, SLACK_ALERT_USER (optional) enable slack threading + error pings
• DATABASE_URL (optional) turns on the postgres sink; set REQUIRE_DATABASE=true if csv-only mode should hard fail
• concurrency and startup knobs live behind envs: SCHOOLYANK_MAX_CONCURRENCY, SCHOOLYANK_MAX_SCRAPE_ATTEMPTS, SCHOOLYANK_MAX_RATE_LIMIT_ATTEMPTS, SCHOOLYANK_BROWSER_START_*
• logging: set LOG_FILE to capture a rolling log, STATUS_CSV_PATH to relocate the status tracker
• docker compose uses the same envs; docker-compose up brings up postgres + the scraper worker if you like running this in a box

• default per-school csv: output/.csvt;.csv
• schools csv mode writes to schools///.csv/<Hs ID>.csv so nothing collides
• merged batch csv lands at output/all.csv unless you override it
• status tracker lives at output/status.csv (per run)
• when postgres is configured the upsert target is public.extracted_teachers
• log files go wherever LOG_FILE says; otherwise stdout/stderr is all you get

• no staff directory → no teachers; portals that hide everything behind a parent login still beat the agent
• smtp validation needs port 25 — most home ISPs block it, so expect “inconclusive” spam in that case
• captchas, sso walls, and “enter your student id” forms still end the ride
• directories that obfuscate emails with weirdo javascript (other than finalsite) require manual cleanup
• output counts can wobble by a few teachers run-to-run because the agent explores in a slightly different order every time
• long-running batches should stay under whatever your computer can cool; --max will happily light all cores

• bun index.ts --help prints the full flag bible with prettier formatting
• bun run preflight standalone env check (same as the --preflight flag)
• bun run stats quick aggregate counts over everything in schools/
• bun run clean:teachers re-validates dist/teachers.csv in chunks with OpenAI web search (set OPENAI_API_KEY first)
• bun run rank scores teachers out of 100, pulls web presence (Exa/DDG), and emits ranked csvs per school
• bun run typecheck keeps the bun + typescript types honest
• python helpers live in scripts/ for bulk csv surgery if you enjoy command-line archaeology

thats it. go spam some teachers!! (legally) and send them something nice.

this is a vastly improved version of https://github.com/Hex-4/schoolyank by @Hex-4 thank you for the direction!!
