Infrastructure you stop maintaining

An agent can scaffold all of this. The question is who maintains it when the agent session ends.

HTML pages

Deploy landing pages, microsites, portfolios. Public URLs. No hosting to manage.

Forms + validation

Required fields, types, min/max, regex patterns, duplicate rejection. Stored and queryable.

Live dashboards

Seven widget types. Pie charts, bar charts, line charts, tables, metrics. JSON in, dashboard out.

Webhook delivery

HMAC-signed payloads. Retries. Delivery logs. Slack and Discord formatting built in.

Custom domains

Point your own domain at your pages and forms. Automatic SSL. DNS verification built in.

Upsert API

Insert or update submissions by externalId. Keep data in sync without managing state.

Static assets

Upload images, fonts, and files. Serve them from CDN URLs. Per-plan storage limits.

The boring stuff

Rate limiting. GDPR deletion. CSV export. Dedup. Submission caps. File uploads. Handled.
