Get your API key by signing up [here](https://helicone.ai/signup) and add credits at [helicone.ai/credits](https://us.helicone.ai/credits)\n\n2. Update the `baseURL` in your code and add your API key.\n\n   ```typescript\n   import OpenAI from \"openai\";\n\n   const client = new OpenAI({\n     baseURL: \"https://ai-gateway.helicone.ai\",\n     apiKey: process.env.HELICONE_API_KEY,\n   });\n\n   const response = await client.chat.completions.create({\n     model: \"gpt-4o-mini\",  // claude-sonnet-4, gemini-2.0-flash or any model from https://www.helicone.ai/models\n     messages: [{ role: \"user\", content: \"Hello!\" }]\n   });\n   ```\n\n3. 🎉 You're all set! View your logs at [Helicone](https://us.helicone.ai/dashboard) and access 100+ models through one API.\n\n---\n\n### Self-Hosting Open Source LLM Observability\n\n#### Docker\n\nHelicone is simple to self-host and update. To get started locally, just use our [docker-compose](https://docs.helicone.ai/getting-started/self-deploy-docker) file.\n\n```bash\n\n---\n\n## License\n\nHelicone is licensed under the [Apache v2.0 License](LICENSE).","github_created_at":"2023-01-31T22:34:44+00:00","created_at":"2026-07-07T17:34:46.215082+00:00","updated_at":"2026-08-17T12:01:09.256449+00:00","categories":[{"slug":"evaluation-observability","name":"Evaluation & Observability","url":"https://www.graphcanon.com/categories/evaluation-observability","markdown_url":"https://www.graphcanon.com/categories/evaluation-observability.md","api_url":"https://www.graphcanon.com/api/graphcanon/categories/evaluation-observability"}],"tags":[{"slug":"agent-monitoring","name":"agent-monitoring"},{"slug":"analytics","name":"analytics"},{"slug":"evaluation","name":"evaluation"},{"slug":"gpt","name":"gpt"},{"slug":"langchain","name":"langchain"},{"slug":"llm-cost","name":"llm-cost"},{"slug":"llm-evaluation","name":"llm-evaluation"},{"slug":"llm-observability","name":"llm-observability"}],"trust":{"provenance":{"is_fork":false,"github_id":595832198,"owner_type":"Organization","methodology":"github_public_v1","parent_repo":null,"near_duplicate_slugs":[]},"computed_at":"2026-08-17T12:01:08.133Z","maintenance":{"label":"Very active","score":96,"methodology":"github_public_v1","releases_90d":0,"days_since_push":0,"last_release_at":"2025-08-21T18:47:38Z","stars_delta_30d":110,"open_issues_delta_30d":41},"security_summary":{"status":"no_lockfile","scanner":null,"low_count":0,"high_count":0,"last_scan_at":"2026-07-11T11:04:01.332Z","medium_count":0,"scan_profile":"none","critical_count":0}},"capability_facts":{"mcp":{"source":"repo_scan","observed_at":"2026-08-17T12:01:08.640Z","server_manifest":false},"scan":{"source":"repo_scan","observed_at":"2026-08-17T12:01:08.640Z"},"deploy":{"source":"dockerfile:Dockerfile","self_host":true,"observed_at":"2026-08-17T12:01:08.640Z","managed_saas":false},"languages":{"value":["typescript","javascript"],"source":"github.language+package.json","observed_at":"2026-08-17T12:01:08.640Z"},"has_docker":{"value":true,"source":"dockerfile:Dockerfile","observed_at":"2026-08-17T12:01:08.640Z"},"license_spdx":{"value":"Apache-2.0","source":"github.license","observed_at":"2026-08-17T12:01:08.640Z"}},"decision_facts":{"hosting":null,"pricing":null,"requirements":null,"constraints":null,"when_to_use":["Use Helicone when you need an open-source solution that can monitor a wide range of LLMs, including more than 100 available through one API.","Choose Helicone if your project benefits from being part of the YC W23 cohort and seeking advanced prompt engineering analytics."],"when_not_to_use":["Do not use Helicone if you have strict data privacy needs that are better served by fully localized or proprietary observability solutions.","Avoid using this platform if your project specifically requires real-time integration with a specific model outside of Helicone's extensive but curated list."],"source":"enrich:decision_facts","observed_at":"2026-07-14T21:15:24.757Z"},"constraint_facets":null,"decision_summary":[{"label":"Adopt for","value":"Helicone is an open-source platform for monitoring and evaluating language models with features specifically designed to facilitate integration and offer detailed observability."}]}}
