WHY THIS EXISTS
Open source built the internet.
Bureaucracy is what's stopping it from scaling.
Every app on this page is free, inspectable, and forkable. Open source is the closest thing software has to a public good — it's how a solo developer in any country gets the same database engine, the same web framework, the same AI tooling as a trillion-dollar company. That's the actual democratization story. Not a slogan — a fact you can verify by reading the source.
Nexlayer exists to finish that story on the infrastructure side. The code was already free. What wasn't free was the six-figure platform team, the weeks of YAML, the tribal knowledge required to take that code from a laptop to something that survives real traffic. We closed that gap: describe the app, and it deploys, scales, and stays up — no cluster expertise required. That's what "democratizing infrastructure" has to mean if the phrase is going to mean anything: the distance between an idea and a running, internet-scale service should be minutes, not a hiring plan.
DevOps is done.
Not "evolving." Not "shifting left." Done — as a discipline anyone should still be building a growing business around in 2026.
DevOps sold itself as the bridge between writing code and running it safely at scale. What it actually became, for most companies that aren't hyperscalers, is a full-time tax: a standing team whose job is translating application intent into YAML, tickets, and pipeline configuration by hand. That team doesn't make your product faster, safer, or more correct. It makes change slower and gives you a body of process to point to when something breaks. That's perceived value — the comfort of a process — not real value, which is uptime, velocity, and margin. A growing business pays for the appearance of control while actually getting less of it, because every change now routes through people whose job is the infrastructure, not the product.
That's the honest description of a cancer: a structure that consumes resources, grows regardless of whether it's helping the host, and crowds out the thing that was supposed to scale. An enterprise's ability to scale without compromise — technical or financial — degrades in direct proportion to how much of its engineering org exists to operate infrastructure instead of building on top of it. The apps on this page didn't need that team. They needed a description of what to run.
250 Open Source Apps
Ranked & Scored
Every app from the #250apps challenge, rated on scalability, security, engineering quality, and real-world deployability on Nexlayer.
Zitadel
88.3Modern cloud-native identity platform providing OIDC/SAML, multi-tenancy, and passwordless auth out of the box. Standout trait is being built from day one for horizontal scale with event-sourced state in a single Go binary.
Keycloak
87.5A full-featured, battle-tested identity and access management server supporting OIDC, SAML, and LDAP federation, originally the base for Red Hat SSO. Standout trait is genuine enterprise-grade IdP capability with proper backend-managed auth and clustering.
OpenFGA
86.3Fine-grained authorization engine implementing Google Zanzibar-style relationship-based access control, now a CNCF project. Standout trait is expressing complex permission models (nested groups, hierarchies) as a queryable relationship graph rather than brittle role lists.
SuperTokens
81.0Open-source user authentication and session management platform with backend SDKs for Node, Python, Go, and Java, positioned as a self-hosted alternative to Auth0 or Firebase Auth.
Authentik
79.0Full-featured open-source identity provider supporting SAML, OIDC, LDAP, and SCIM — a legitimate self-hosted alternative to Okta/Auth0. One of the more properly-architected security products in this batch.
Ory Hydra
78.0Certified OAuth2/OIDC server implementing the protocol as a headless, API-driven service that delegates login/consent UI to a separate app. Standout trait is a clean separation between the OAuth2 protocol engine and identity/UI concerns.
Logto
76.8A modern, developer-friendly identity provider offering OIDC, social/enterprise SSO, MFA, and RBAC out of the box. Standout trait is a genuinely pleasant developer experience compared to older IdPs like Keycloak, without sacrificing backend-managed security.
