Frequently asked questions
Markup Hero scores C on the API Report Card. The only public API is a browser JavaScript embed with two methods, createMarkup and openMarkup; there is no server-to-server REST API. Tokens and pricing are gated behind a sales conversation. The fuller Integration API remains an unshipped roadmap item.
Markup Hero has an official API, but teams routinely hit its limits: gated access, partial coverage, or paid tiers. Most end up supplementing it with exports or an unofficial API layer like Supergood.
Markup Hero is a web-based screenshot, file and image annotation tool founded in early 2020 by Jeff Solomon (5x founder, ex-Velocify) with co-founders Nicolas Russo Larsson and Glib, based in Culver City, California.
Vertical: misc / horizontal developer & productivity tooling. Markup Hero does not map to any of Supergood's named verticals (Legal / Healthcare / Real Estate / Compliance / Financial Services). It is a horizontal collaboration utility. Capturing a region/window/full-page screenshot from the desktop client or Chrome extension and adding arrows, text callouts, numbered steps, blur (for redaction) and shapes.
Low-to-mid. Markup Hero is a known name in the screenshot/annotation category but is not a category leader. G2 lists it with a moderate review base, Capterra and GetApp carry profiles, and it has a heavy AppSumo lifetime-deal footprint.
Markup Hero stores user-generated visual artifacts and the metadata around them; it is not a system of record for any regulated vertical data.
Founded 2020, so the codebase is modern by construction: a browser-first SPA, Chrome Extension (Manifest V3 era), desktop wrappers for Mac/Windows/Linux, public asset CDN at `static.markuphero.com`, and a JavaScript Annotation API delivered as a single async `<script>` tag.
Only a browser JavaScript SDK ships, no server-to-server REST API, no Node/Python/PHP/Ruby/Go SDKs, no mobile SDKs. No webhooks, no event subscriptions, purely synchronous request/response inside the browser. Full sourced list under Sources below.
Common alternatives include TechSmith Snagit, CleanShot X, Zight (formerly CloudApp), Droplr, ShareX, Lightshot. Graded alternatives appear under "More from the report card" below.
Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
