Plinth: Three Small Tools for Solo Infrastructure

plinthrun.com Observed source

Editorial interest 78/100 Selection signal · not a rating of the site

An open-core toolkit bundling static-site forms, an inspectable webhook inbox, and browser-based JSON repair.

Landing page captured for the 2026-09-04 issue.

Field notes

The Schema tool accepts malformed objects containing LLM prose, trailing commas, Python literals, or truncated braces, then offers browser repair or an API path with optional JSON Schema validation. Plinth also separates form submission from webhook inspection: Forms can store or forward static-site POSTs, while Catch exposes webhook headers and bodies in a bin. The page lists browser repair as unlimited, with the hosted API free for 100 calls per day.
