What is HOL Guard?
Local-first runtime control for AI coding agents from Hashgraph Online. Approves or denies shell commands, secret-file reads, MCP server changes, and plugin/skill installs before they run. Apache-2.0 open source and free. Not a cloud MCP gateway, complete prompt-injection preventer, secrets manager, or SCA replacement.
What is Stytch?
Stytch is a developer-first authentication and user management platform built to make modern, secure login easy to implement. Rather than wrestling with the complexity of building auth yourself — sessions, password resets, multi-factor authentication, fraud prevention — developers can use Stytch's APIs and SDKs to ship a polished, secure sign-in experience in a fraction of the time, and then focus on their actual product.
Stytch's strength is breadth of authentication methods with a clean developer experience. It supports passwordless options like magic links, one-time passcodes and passkeys, alongside traditional passwords, OAuth social logins, and enterprise SSO. Multi-factor authentication, session management and embeddable UI components come built in, so you can offer whatever login flow fits your users while keeping the implementation simple and well-documented.
Beyond core auth, Stytch has invested heavily in security and fraud prevention — device fingerprinting, bot detection and intelligent risk signals help stop fraudulent sign-ups and account takeovers without adding friction for legitimate users. It also offers B2B-focused features like organization management, role-based access control and SCIM, which are essential for SaaS companies selling to businesses. With flexible APIs that let you build fully custom flows, plus pre-built components for speed, Stytch suits both teams that want control and teams that want to move fast. For developers who see authentication as critical but don't want to spend months building and maintaining it, Stytch offers a modern, secure, and genuinely pleasant alternative to rolling your own or settling for clunky legacy providers.
