# Inquir Compute > Serverless backend for AI agents, APIs, cron jobs, webhooks, and background jobs. Node.js 22, Python 3.12, and Go 1.22 run in isolated containers behind one API gateway — with pipelines, hot containers, layers, and browser deploy. No Kubernetes. Public marketing and documentation live on **https://inquir.org** (English). The same routes are available in Russian at **https://inquir.ru**.
