What is Retool?

Best Human-in-the-Loop Automation Platforms 2026

Eight platforms are ranked here on a single mechanism: how a person enters an automated path, and what the system can prove afterward about the decision they made. Moxo scores 7.7 and ranks first; Camunda 8 scores 7.2, Microsoft Power Automate 7.1, Pega 6.9, n8n 6.7, Zapier 5.9, Kissflow 5.8 and ServiceNow 4.8, scored 22 September 2026 on the five weighted criteria. Those criteria cover the step type, the approver's account or licence, the routes available on a rejection, the audit record, and the meter that charges for the decision, and none of them can tell a review from a rubber stamp, so the methodology adds a check readers can run on any product in a few minutes: whether the decision record tells a considered approval from an instant one. Every figure was read from a vendor-owned surface and carries its own date.

Best Automation Platforms for AI Orchestration 2026

This ranking answers one question: how many real business applications can an AI agent act on out of the box? It evaluates nine platforms as of August 2026 on the reach they give an agent, not on the workflow logic they can express. That boundary is deliberate, because two neighbouring pages on this site answer different questions. Best Process Orchestration Platforms 2026 scores multi-step process control, error handling and state management. Best AI Agent Platforms 2026 scores building and hosting the agent itself. This page scores the layer between them: the connective tissue that lets an agent already built elsewhere reach the applications a business actually runs on. A platform that leads one of those pages can place low here, and two of them do. Scores derive from application and action catalogue counts, the exposure model each platform uses to publish those catalogues to an agent, setup effort, failure handling and cost per agent action. Every figure was retrieved from a vendor-owned surface on 11 August 2026 unless an earlier date is stated against it.

Moxo vs Gumloop in 2026: Texting the Client, or Building the Agent

Gumloop (founded 2023) builds AI agents a company's own staff run; Moxo, whose predecessor Moxtra was co-founded in 2012, runs processes that wait on people outside the company. Gumloop wins three rounds to two: the way in, per-tool gating and a priced overage. Moxo wins on texting a client a step and on what that client can be asked to do. Vendor pages and docs were read on 28 September 2026.

Moxo vs Relay.app in 2026: Where Relay's Approval Workflows Can Go Next

Relay.app, founded in 2021, shut down in September 2026 and deleted every account, workflow and run history; Moxo, whose predecessor Moxtra was co-founded in 2012, is one destination for its human-in-the-loop users. Relay.app takes two rounds, Moxo one, and vendor risk is a draw. The page maps which Relay steps Moxo replaces, on which plan, and what the shutdown teaches about exports, from sources read 28 September 2026.

Moxo vs Workato in 2026: The Integration Estate, or the Approval Inside It

Workato, founded in 2013, is an enterprise integration platform whose Workflow apps add human tasks to recipes; Moxo, whose predecessor Moxtra was co-founded in 2012, ships the human step itself. Workato wins three rounds to two: connector reach, change control and the way in. Moxo wins the human step and retries. Vendor pages and docs were read on 28 September 2026.
