Auth0

What is Auth0?
Auth0 is a customer identity and access management platform from Okta. It handles authentication and authorization for web, mobile, and API applications so development teams can add login, SSO, and access controls without building identity infrastructure from scratch.
The platform covers B2C consumer apps, B2B SaaS products, and internal tools. Developers integrate via SDKs and quickstarts for stacks like React, Next.js, iOS, Android, Java, .NET, and Python. Auth0 also ships dedicated tooling for securing AI agents, including user authentication before agent access, Token Vault for scoped API credentials, and fine-grained authorization for RAG pipelines.
Auth0 reports blocking 3 billion-plus attacks monthly across Okta and Auth0 platforms, 99.99% uptime, and 10 billion-plus authentications per month. Customers listed on the site include Siemens, Signify, Zapier, Wyndham Hotels, and the City of Los Angeles.
Opinionate

What is Opinionate?
Opinionate runs structured debates on topics you choose or let the site suggest, using steelmanning to build the strongest opposing case before you defend your view. Each session plays out as a text debate you read through instead of a quick bullet summary. That helps you stress-test ideas without knocking down a weak strawman.
Debate prep tools usually hand you bullet summaries. Opinionate simulates back-and-forth argumentation with a daily usage cap on the free tier, then sells one-time Boost packs when you want more runs without a subscription. That model fits occasional decision checks rather than all-day research sprints.
Students, writers, and team leads use Opinionate to rehearse tough conversations, explore policy tradeoffs, and settle friendly arguments. The homepage promotes code DEBATER10 for 10 percent off Boost purchases on the pricing page.
