Scalekit
Auth Stack for AI Apps | Start Free
TL;DR
Scalekit provides a modular authentication stack tailored for AI applications, securing SaaS apps, MCP servers, AI agents, and enterprises with features like OAuth for agents, SSO, SCIM, and passwordless auth. It's ideal for fast-moving AI startups and B2B SaaS teams needing quick, scalable identity without migration. Key differentiator: AI-first design with agent auth and org-centric multi-tenancy, free tier up to 1M MAUs.
Our Take
Scalekit positions itself in the niche but growing market for authentication solutions optimized for AI-driven applications, particularly those involving AI agents, MCP (Model Context Protocol) servers, and B2B SaaS with enterprise needs. Its primary value proposition is modularity—add specific auth components like agent OAuth or SSO without overhauling existing systems—making it appealing for developers prioritizing speed and AI-specific security over general-purpose IAM bloat. With SOC 2 compliance, multi-region hosting, and a generous free tier, it targets startups scaling AI features rapidly. Strengths include exceptional developer experience (clean SDKs, thorough docs), proactive support, and AI-tailored features like delegated agent access and MCP OAuth, which stand out amid rising agentic AI demands. G2 reviews highlight seamless integration and time savings, enabling focus on core AI innovation. Transparent, org-based pricing avoids MAU pitfalls of rivals. Limitations may arise for non-AI use cases or teams needing ultra-mature enterprise features, as it's a young company (founded 2023). Review volume is low (~20 on G2), potentially indicating limited adoption; Reddit feedback is anecdotal/promotional. Lacks visible cons in accessible data, but scaling beyond free tier or custom needs could reveal gaps. Best suited for AI startups, B2B SaaS CTOs building agentic apps, and teams valuing DX over vendor lock-in—especially those avoiding Auth0's complexity or Cognito's rigidity.
Pros
- + Easiest auth integration with clean SDKs and straightforward documentation.
- + Proactive, top-tier customer support praised across testimonials and G2.
- + Generous free tier (1M MAUs, 100 orgs) ideal for startups.
- + AI-specific features like MCP/agent OAuth eliminate custom auth work.
- + High G2 ratings (4.8/5) for speed and reliability in B2B/AI contexts.
Cons
- - Young product (launched ~2023), potentially lacking long-term enterprise maturity.
- - Sparse independent reviews; most feedback from testimonials or affiliates.
- - May over-specialize in AI/MCP for general SaaS without agent needs.
- - No detailed cons surfaced in G2 snippets or Reddit; infer potential scaling/support limits at high volumes.
- - Company HQ/founding not on site, relying on external sources.
