Popular order starts with editorial picks, then ranks providers by monthly downloads of mapped SDKs on npm and PyPI (refresh attempted 2026-10-26; unavailable measurements retain older counts). Other profiles follow A–Z. Category totals cover the full directory; letter counts reflect the current search and category. Profiles can belong to multiple categories. Counts reflect unique named profiles returned by the API catalog for this directory. Availability of documentation and integration details varies by provider.
