Pastebin / Snippet Hosting
Store snippets as text or markdown, retrieve them by id, and optionally render preview.
IntermediateWebPlatform
Users submit content to an API that stores it and returns a short id; the retrieval path serves the stored content quickly and can optionally render a preview for supported formats using a lightweight preview service.
When to use it
- Content is mostly immutable once created and retrieved by id
- The system benefits from a very simple data model and straightforward CRUD endpoints
Trade-offs
- Large or many snippets can bloat the store and make retrieval or indexing expensive
- Preview rendering adds another service and a rendering pipeline to support

How it works
- A snippet is stored under a generated id, with the content itself typically in object storage and only metadata in the database.
- Reads are id lookups served from cache, making the read path nearly identical to a URL shortener's.
- Optional expiry and visibility rules are enforced at read time and swept by a background job.
Used in the wild
- Sharing logs, stack traces and configuration snippets.
- Code snippet hosting with syntax highlighting.
- Temporary content with an automatic expiry.
Good to know
- Unlisted-by-URL is not access control. Anything genuinely sensitive needs real authorisation, because 'nobody will guess the id' fails as soon as the link is pasted into a ticket or search-indexed.
- These services are heavily abused for malware staging and credential dumps, so content scanning and abuse reporting are operational requirements rather than nice-to-haves.
