 Infrastructure is governance. Fairvisor builds tools for explicit, enforceable control over API traffic, cost, and access policies.
We believe infrastructure decisions are business decisions. Traffic distribution, rate limits, and enforcement policies shape cost, reliability, and power dynamics inside digital systems. Fairvisor exists to make those decisions explicit and controllable.
See how it works Why Fairvisor Exists The structural problem. Cloud defaults optimize for convenience.
High-traffic APIs expose cost volatility.
AI workloads amplify extraction and abuse.
At scale, “just autoscale” stops being a strategy. Unbounded traffic becomes financial risk. Black-box infrastructure becomes governance risk.
Fairvisor was created to treat traffic, limits, and enforcement as first-class business controls — not side effects of infrastructure.
Principles Infrastructure is a responsibility Every technical decision distributes resources: compute, money, access priority. We believe those decisions should be made deliberately — owned by the product team, not left to whatever the default configuration happens to enforce. Constraints create resilience Infinite scale doesn’t exist. Traffic growth, automation, and AI workloads make that obvious. We design for measurable resources, explicit limits, and predictable behavior. A managed failure is better than an uncontrolled overspend. Transparency over abstraction Convenience shouldn’t cost you understanding. Teams should be able to see which rules are active, which policies apply, and how they affect load and cost. Observability, audit, and explicit controls aren’t nice-to-haves — they’re what mature infrastructure looks like. Protection is a foundation, not a feature Public systems will face automated traffic, scraping, and value extraction. That’s not a threat to prepare for eventually — it’s the baseline condition. Fair resource enforcement isn’t an add-on to your API architecture. It is the architecture. Founder Lev Leontyev Infrastructure engineer and engineering leader.
Industry veteran with more than two decades of experience in backend systems, performance-critical services, and engineering management. Has built and operated production systems under real traffic, real cost pressure, and real operational constraints.
Fairvisor is a direct continuation of that experience.
It reflects a long-term focus on:
– explicit architectural decisions
– cost-aware infrastructure
– enforceable policy control
– measurable performance constraints
The company is built deliberately: conservative where stability matters, opinionated where governance matters, and transparent by design.
How We Build Open-edge + SaaS control plane The edge runs on your infrastructure and is open source. The control plane handles policy management, enforcement orchestration, and observability integration. Explicit specifications before code Every feature starts with a written spec. Ambiguous behavior is resolved on paper, not discovered in production. Performance-first on the hot path Enforcement decisions happen in-process with no external calls. Latency budgets are defined, measured, and published. Human architectural control AI-assisted development accelerates implementation. Architectural decisions remain under human review. What We Will Not Do Build opaque systems Traffic management that hides its logic is governance debt. Our policies are readable, auditable, and explicit. Monetize customer data Your traffic stays in your infrastructure. We receive aggregated counters — never request content or user data. Rely on hidden throttling Every enforcement action is visible in the audit log. No silent rate limiting, no unexplained rejections. Design for lock-in The enforcement edge is MPL-2.0. You can fork it, run it independently, and migrate away at any time. Long-Term Direction Enforceable fair usage standards APIs need shared, auditable standards for how access is granted and constrained. We’re building toward that. Infrastructure-level budget control Cost limits should be enforced at the infrastructure layer — not scrambled for after the incident. Resilience against automated extraction Automated traffic isn’t going away. Infrastructure needs native enforcement, not bolt-on patches. Governance as a core layer We see API governance as foundational infrastructure — as essential as networking and storage. Contact Fairvisor is a focused company building infrastructure for teams that need control — not abstraction.
If you treat traffic as a resource, we should talk.
