| # | Tool | Grade | Score | Best for | Price | Where |
| --- | --- | --- | --- | --- | --- | --- |
| 1 | [Temporal](https://www.anchorterminal.com/tools/temporal.md) | BB | 77.2 | A team that already runs, or wants to run, agents as durable workflows with strict guarantees and an audit trail per run. | $0.05 / 1k calls | local |

| 8 | [Node-RED](https://www.anchorterminal.com/tools/node-red.md) | C | 61 | Owners who want event-driven flows on their own machine or device, with a large library of community nodes, and an agent that deploys or edits flows as JSON. | Free · OSS | local |
| 9 | [Prismatic](https://www.anchorterminal.com/tools/prismatic.md) | C | 59.1 | A B2B software company that wants to build integrations once, deploy them per customer and let an in-app agent call them as MCP tools. | Paid | hosted and local |

## How to choose

- Connection setup and authorisation: Check how connections are authorised and whether an agent can create one through the API, since a flow cannot run until its connection exists.
- Action coverage for each app: Check that the email, CRM and database steps a workflow needs exist as named actions, not only as a generic HTTP call.
- Retries and run logs: Check whether failed steps retry under a set policy and whether each attempt is logged, so an agent can tell a transient failure from a broken connection.
- Cost of retries and failures: Check whether each step, retry and failed attempt is billed, since a retry loop can multiply the cost of one completed run.

- How the benchmark tests this category: One workflow across email, CRM and a database on every platform. We compare connection setup, authorisation, action coverage, retries, logs and the cost per completed run.
