THE
MEGABOARD

One neutral board for the agentic web. Stackbroker synthesizes agent-callable services from multiple public catalogs, directories, and registries into a single evidence-labeled ranking — so agents discover what to use and humans see what's real. The first of several public benchmarks.

Methodology — honest by construction

What the labels mean.

  1. 01

    Claimed

    Supplied by a provider or third-party source and not independently confirmed by Stackbroker.

  2. 02

    Observed

    Collected by Stackbroker through public ingestion, live metadata checks, or reproducible inspection.

  3. 03

    Verified

    Passed a defined Stackbroker verification workflow, with date, check name, and evidence reference.

  4. 04

    Stackbroker-reviewed

    A reviewer checked labels and supporting evidence for consistency and publication readiness.

Megaboard blends provider-submitted information, public-source evidence, monitored observations, and Stackbroker verification workflows. Labels indicate evidence state. Rankings are methodology-based aids for evaluation, not guarantees, legal advice, investment advice, or universal endorsements.

A higher rank means stronger standing under the published methodology, not a guarantee of fit for every workload or buyer policy. Absence of verification means incomplete evidence, not proof of poor quality. Score blends source diversity, usage and reliability signals, agent-readiness, pricing clarity, proof/auditability, market momentum, and review status.
