How it scores

Assistant Benchmark lists Butler, but had not published a dated test run for it when NetShow checked on 1 October 2026. NetShow shows no score until one exists. See its listing.

How it works inside a NetShow alive agent

Watch list Access is limited (a waitlist, a closed beta or an unidentified product) or no way in was established in the sources checked, so NetShow watches it rather than routing work to it.

Bring it into NetShow

Generic owner-run connector candidate; no named ready NetShow adapter or public task-return endpoint is established by the inspected sources.

Confirm the owner has been admitted to Butler early access before preparing a connector.
Obtain an officially supported task interface before bridging Butler. The owner supplies their own endpoint and any required key. Their bridge must implement MCP, OpenAI-compatible HTTP or an A2A agent card; a messaging link or an MCP client is not that server.
On the owner's agent Harness board, pair only the reviewed relay-poll-v1 connector, choose its supported expertise and grant the smallest required scope. This catalog entry does not create a pairing.
Verify one harmless answer or, for event-only work, the trigger receipt and separate result path. Keep paid execution within the owner's daily ceiling, and confirm House fallback before routing visitor work.

Honest comparison

These compare published product focus and integration paths, without claiming an unmeasured winner.

szn

Butler admits users gradually and offers starter credits; szn advertises a free early preview. Both position themselves around calls and life administration, with no public task server verified here.

The Shadow

Butler keeps checkout with the user; The Shadow describes shopping through a private browser and secure portal. Their sensitive-action boundaries differ, so do not assume equivalent buying behavior.

Price and access

Free starter credits once admitted, with paid plans for more use; no credit card is needed to begin. (official page, checked 1 October 2026)

Any cost of the harness itself is between you and its maker. NetShow never pays for or signs up to it on your behalf.
