Praxicraft is a hands-on workspace for data practitioners — and the same environment hiring teams use to assess talent.
Engineers solve production-style data engineering workloads in live sandboxes (SQL, Python, Linux, dbt, Airflow, Spark, and more), earn XP, climb ranks, and build a portfolio employers can verify. Organizations use Praxicraft Assess to run realistic technical assessments, live interviews, and multi-stage hiring pipelines — with evidence-backed scores instead of LeetCode puzzles.
Praxicraft itself is a product platform (not open source). This GitHub organization hosts our public developer surface: official SDKs and automation integrations for Assess.
Assess turns data-engineering hiring into something you can automate, measure, and plug into the tools you already use.
- Run realistic take-home assessments in isolated sandboxes — not toy puzzles.
- Invite candidates in bulk, track results, and wire outcomes into your ATS or internal tools.
- Build multi-stage pipelines and live interview rooms with structured signal.
- React to hiring events with signed webhooks (
assessment.completed,candidate.passed, and more). - Connect Assess to your stack through our Public API, SDKs, n8n, Zapier, and MCP.
Day-to-day hiring lives in the Assess dashboard. Connect software when you need it through the Public API and the repos below.
- Assess quickstart — invite your first candidate from the dashboard or API
- Python SDK · Node SDK · Go SDK
- n8n setup · Zapier setup
- Webhooks · Automations · Integrations
- Practice on Praxicraft — solve real data workloads and build your portfolio
Our mission is to make data engineering skill visible — so practitioners can prove what they can ship, and hiring teams can evaluate talent with evidence from real work, not proxies.
