Helicone Tech Stack and Challenges

At Helicone.ai, we combine a cutting-edge tech stack with a focus on solving complex problems in AI observability. Our platform is designed to give developers unparalleled insights into their applications' performance, costs, and behavior, all while being scalable, developer-friendly, and secure.


Tech Stack

  • Languages: TypeScript and Python power our core platform, offering flexibility and reliability for both backend and data-intensive tasks.
  • Frameworks: Next.js, React, Tailwind CSS, Express, and ShadCN form the foundation of our user-facing and backend systems, delivering seamless performance and intuitive interfaces.
  • Hosting: We deploy across Kubernetes, AWS, GCP, Vercel, and Supabase, ensuring scalability and flexibility to meet diverse deployment needs.
  • Services: Core components include Docker, Postgres, Clickhouse, Cloudflare Workers, and Redis, which together enable efficient data storage, processing, and caching for high-throughput systems.
  • LLMs: Our platform supports a variety of large language models, including OpenAI, Anthropic, Gemini, TogetherAI, and more, ensuring compatibility and flexibility for developers.
  • Developer Tools: We rely on Unix, CLI, and git to maintain a robust development workflow.

Challenges We’re Tackling

  1. Real-Time Observability at Scale:
    Building a platform that processes millions of events in real time requires highly optimized data pipelines. With Clickhouse and Redis, we ensure low-latency data ingestion and querying to deliver actionable insights instantly.

  2. Unified LLM Integrations:
    Supporting multiple LLM providers means creating unified abstractions that simplify diverse APIs. Developers can seamlessly integrate and switch between providers like OpenAI, Anthropic, and Gemini without additional overhead.

  3. Prompt Management and Experimentation:
    We empower developers to track prompt versions, run experiments, and analyze metrics like cost, latency, and accuracy. This enables fine-tuned optimizations to improve performance and ROI for LLM applications.

  4. Data Privacy and Security:
    With enterprise customers relying on our platform, we maintain SOC 2 and GDPR compliance while implementing features like rate limiting, access control, and secure caching to safeguard sensitive data.
