Airtable vs Rendex

Airtable pairs a spreadsheet-style grid with a full relational database and automation engine, and exposes every base through a REST API for reading, writing, and querying records programmatically. Classic API keys were retired in February 2024 in favor of scoped personal access tokens and OAuth2 apps, both still authenticated as bearer tokens. The free plan includes real API access (rate-limited to 5 requests/second per base), with paid tiers raising throughput rather than gating access.

Rendex runs headless Chromium across a global edge network to turn live URLs, raw HTML, or Markdown into pixel-perfect PNG, JPEG, WebP, or PDF output, including full-page scroll-stitched captures. It also supports templated batch jobs across many URLs at once and HMAC-signed webhook callbacks, on a metered free tier with paid plans billed per rendering call.
