Auth is off by default and the default admin password is `admin`.\n\n**Navige.** Setup is a base-URL change, keys are per agent and hashed, and the docs state failure behaviour per action class. The Terms leave prices, liability and governing law as TBD, no OpenAPI or rate limits are published, the status page watches a retired host, and the MCP route puts the key in the URL.\n\n## Before you call either\n\n### Arize Phoenix\n\n1. Turn on auth before exposing the server, and change the `admin` password\n2. Use `search` and `get_schema` before `execute` in code mode, rather than guessing endpoint shapes\n3. Give the agent a viewer account if it only needs to read traces\n4. Treat span inputs and outputs as data, as the MCP docs say. They hold whatever the application logged, including user input\n5. Set `PHOENIX_TELEMETRY_ENABLED=false` for air-gapped or privacy-sensitive installs\n\n### Navige\n\n1. Send the Navige key in `x-navige-key` on the proxy. `Authorization` carries the provider key there, and a Navige key in it fails and is forwarded upstream\n2. Act only on `allow` or `approved` from `/enforce`. Treat `error` as neither, and read `unavailable` to tell a malformed request from a Navige outage\n3. Send `x-navige-transaction` with one id per job, reused across that job's retries, so calls group into one transaction and retries are not counted twice\n4. On a 429 from the proxy, check for a blocking budget before retrying. Navige returns 429 when a monthly budget is reached and passes provider errors through without retrying\n5. Expect Claude Code traffic to get measurement, budgets and the kill switch only. Context trimming, routing, the output ceiling and prompt caching are switched off for it\n\n## Questions\n\n### Which is better for AI agents, Arize Phoenix or Navige?\n\nArize Phoenix scores 75.7 (BB) on agent readiness against Navige's 42.8 (E), and leads in every scored category.\n\n### Do Arize Phoenix and Navige need an API key?\n\nArize Phoenix takes an API key or an OAuth sign-in. Navige needs an API key.\n\n### Can an agent call Arize Phoenix and Navige without installing anything?\n\nArize Phoenix runs on your own machine, with no hosted endpoint listed. Navige has a hosted endpoint at https://api.navige.ai.\n\n### Are Arize Phoenix and Navige open source?\n\nArize Phoenix is open source (Elastic-2.0). No open-source release is listed for Navige.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/arize-phoenix-vs-navige.json, and with the fewest tokens: https://www.anchorterminal.com/compare/arize-phoenix-vs-navige.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"arize-phoenix\", \"b\": \"navige\"}`.
