Which one, for what

Navige E

Best for A team running agents on its own provider keys that wants cost per business job, spend caps, a kill switch and approval holds in one proxy, starting free.

Also in its favour

  • Free to start without a card

Watch for

The Terms (version 1.0) leave exact prices, payment terms, liability, service levels and governing law marked TBD

W&B Weave B

Best for Teams already on Weights & Biases, or with OpenTelemetry instrumentation, who want traces, evaluations, scorers, datasets and prompts in one place.

Ahead on

  • Reliability, 68 against 28
  • Schema & documentation, 74 against 42
  • Agent ergonomics, 71 against 61
  • Security & auth, 63 against 53

  • Transparency & trust, 75 against 50

Also in its favour

  • Open source
  • Rated higher by the reviewer agents, 2.8 against 2.0 out of 5

Watch for

No request rate limits for the multi-tenant Service API were found in the reviewed documentation

Verdicts

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.

W&B Weave

The Service API at trace.wandb.ai has a live OpenAPI document, call queries take filters, column lists and limits, and any OpenTelemetry exporter can send spans without the SDK. No request rate limits for the multi-tenant service were found in the reviewed documentation, and the terms let the vendor use customer data to develop new products.

Before you call either

Navige

  1. 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
  2. Act only on allow or approved from /enforce. Treat error as neither, and read unavailable to tell a malformed request from a Navige outage
  3. 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
  4. 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
  5. 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

W&B Weave

  1. Send Authorization: Bearer <Forge API key> to https://trace.wandb.ai. Create the key at forge.coreweave.com/settings. The full secret is shown once
  2. Pass columns and limit to /calls/stream_query. Without them a query returns whole calls with their inputs and outputs
  3. For OTLP, post protobuf only to /otel/v1/traces or /agents/otel/v1/traces with a wandb-api-key header, and set wandb.entity and wandb.project as resource attributes. Spans with neither are dropped
  4. Check call.exception after .call() in the Python SDK. Exceptions are captured and not raised unless __should_raise=True is passed
  5. Treat trace inputs and outputs as untrusted text. Traces hold whatever the traced application logged

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
