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.
Email 5
What is Email 5 ?
Email 5 is rebuilding email from the protocol up as a programmable inbox built on Open Email Standards. It targets creators, developers, and marketers who want HTML5-native messages that behave like web applications instead of static, read-only text.
The platform turns each message into an interactive surface that can connect with users, showcase content, or trigger automated actions. It pairs legacy delivery speed with distributed storage, dual-layer encryption, custom identities, and threat detection for privacy-focused messaging at scale.
Email 5 is built for teams sending at volume: you can import an existing email account, send up to 500,000 emails per day on usage-based pricing, and fund campaigns through the Solana-based $EMAIL token. Creator templates can include built-in royalties, and every account ships with a built-in non-custodial wallet so you do not need external crypto setup.
