G8KEPR vs Helicone (now Mintlify, maintenance mode)
Helicone was a well-built AI gateway and observability platform with native prompt injection detection (Meta Prompt Guard), semantic caching, LLM evaluations, and strong cost analytics. In March 2026 Helicone was acquired by Mintlify and entered maintenance mode — security patches and bug fixes only, with Mintlify actively advising users to migrate to LiteLLM or Portkey. If you are evaluating Helicone, understand that no new features are planned and the platform's long-term future is uncertain. G8KEPR is an actively developed platform: it covers traditional API traffic, runs its own ML threat classifiers, adds complete MCP agent security, and includes an inline Verification Engine on every output.

The Four Pillars
G8KEPR is a unified platform. Four capabilities working together that no single-purpose tool can match.
AI Gateway
Multi-LLM routing, automatic failover, cost tracking, prompt caching
MCP Security
Secure every AI agent tool call — registration, auditing, sandboxing
AI Threat Detection
Prompt injection, jailbreak attempts, PII leakage — 1,700+ ML patterns
Verification Engine
Structural, semantic, and constraint verification of every AI output
