Fly.io

How to use Fly.io in a web scraping pipeline

Fly.io runs applications composed of processes and Machines. It can host the worker code for a scraping pipeline when you need to control the runtime rather than call a managed scraping API.

A practical workflow

1. Package your scraper and its dependencies as an application process that receives work from a queue or controlled endpoint.
2. Run the worker on Fly.io, fetch and parse allowed targets, and write captures and validated records to external storage.
3. Report each job's outcome to the coordinating application so failed work can be reviewed or retried deliberately.

When it fits

Consider it when existing HTTP or browser automation code needs an operated runtime with application-level configuration. Separate collection workers from the user-facing API so a slow target does not hold open an ordinary application request.

Boundaries

Fly.io supplies hosting, not extraction rules, a crawl frontier or guaranteed target access. Configure browser dependencies, secrets, networking and persistent storage as required. Process restarts can interrupt work, so preserve progress externally and make destination writes idempotent instead of relying on a worker's local state.
