Tools for people working with digital identities
Free utilities, no signup and no usage limits. They run entirely in the browser: what you paste is never uploaded anywhere, which makes them usable even on payloads containing real data.
If you are looking for what an acronym means rather than a tool, the IAM glossary gathers the definitions of SSO, OIDC, SAML, SCIM, JWT and Zero Trust. To actually integrate authentication, see the developer documentation.
Beyond the tools
Formatting a SAML response helps you understand an error; it does not help you decide which identity platform to adopt. That part takes SDKs, APIs and a conversation about your actual scope.
