Disclosure up front: we make HitLai, one of the tools on this list. The list is honest anyway — it includes our competitors’ genuine strengths, and the option of not switching at all.

Automation used to mean one thing: connect app A to app B and let it run. Then AI started drafting the actual work — emails, quotes, invoices, customer replies — and business owners discovered a new problem: the automation became good enough to be dangerous. A misrouted data sync is an annoyance. An AI-drafted email sent to the wrong customer is an apology call. So a category grew up around a simple idea: pause before the consequential step and let a person decide. If you searched for Zapier alternatives with approval steps, you’re shopping in that category, and this page is the map.

First, what a human approval step actually is — because the term gets stretched. A notification is not an approval step; a notification tells you something already happened. A real approval step stops the run until a person decides. The mechanics are what separate the tools: where the request arrives (email, Slack, a task queue), whether the reviewer can edit the drafted work or only approve and reject, and — the question an accountant or auditor will eventually ask — whether there’s a record afterward of who approved what, and when. Every tool below implements a genuine pause-and-decide step. They differ in where the pause lives and what stands behind it.

Before you switch: Zapier now has approval steps of its own

The honest first entry on any “alternatives to Zapier” list is Zapier. It now ships a built-in Human in the Loop capability: a Request Approval action pauses the Zap while one or more reviewers approve, decline, or change the data submitted for review; a Collect Data action pauses to gather input; and a trigger fires when an approval is requested so you can log or route it. Approval notifications can go to email or Slack. It’s available on Pro plans and higher, each Human in the Loop action counts as a task, and reviewers need access to the Zap itself. If your stack already runs on Zapier and you need occasional approvals on a handful of steps, adding the built-in step is far less disruptive than migrating. The honest reason people still switch: in Zapier, approvals are steps added to a data-pipeline product. In the tools below, the pause is closer to the point of the product.

Relay.app: approvals as a first-class feature

Relay.app is the tool most often recommended for this search, and the recommendation is deserved. Human-in-the-loop steps are the centerpiece of the product rather than an add-on: a run pauses at an approval step, the assignee gets an interactive Slack or email notification with the relevant context inline, and they can approve, reject, or edit the result before the run continues — including straight from Slack, without opening the app. Human-in-the-loop features are included in every Relay.app plan at no extra cost. If what you want is team-oriented, app-to-app automation with collaborative approvals woven through it, Relay.app is a strong choice.

n8n: approval gates for technical teams

n8n is the option for teams with engineering skill who want to run the automation themselves — it’s source-available and self-hostable. Its human-in-the-loop design has a detail worth admiring: the gate is enforced at the tool level, not just the workflow level, so an AI agent can freely do safe things like search a knowledge base while risky actions — sending an email, updating a record, deleting data — wait for a person. Approval requests can go out over Gmail, Outlook, Slack, Telegram, WhatsApp, Microsoft Teams, or Discord, and the response can be an approve/deny button, free text, or a custom form the reviewer edits before submitting. The trade is the standard self-hosting trade: total control, and you’re the one maintaining it.

Lindy: an AI assistant that asks first

Lindy sells AI agents — the “AI employee” framing — rather than pipelines. Its approval mechanic is a per-action toggle: turn on Ask for Confirmation for any action with side effects (sending an email, updating a record, creating a calendar event) and the agent prepares the work, parks it as a draft in the task view, and waits. You approve from the task view or from the email it sends you, and only then does the action execute. For a solo operator who wants an assistant that never acts unilaterally, it’s a clean model.

HitLai: governed work, not just gated steps

HitLai — ours — starts from the same conviction as everything above: the pause is the feature. The difference is the frame. HitLai’s AI drafts the work itself — quotes, customer replies, invoices, purchase orders — from your business’s own data, and you set a trust dial for what happens next: routine actions flow through on their own, and the ones you designate — typically anything that touches customers or money — pause for a person’s approval. HitLai never moves money on its own. Every approval is recorded in a timestamped, tamper-evident audit trail, so “who approved this and when” has an answer months later. Approvals respect roles: a junior team member can draft, a manager signs off. We maintain the platform — patches, monitoring, the audit infrastructure — and it connects to the tools small businesses already run on, including Gmail and QuickBooks. And if you’re the build-it-yourself type, the orchestration core is open source: AICtrlNet Community Edition is MIT-licensed and self-hostable.

Zapier moves data between apps. HitLai runs work your team approves.

How to choose, honestly

  • You’re on Zapier and need occasional approvals: stay, and use the built-in Human in the Loop step (Pro plan or higher).
  • You want team workflows with collaborative approvals throughout: Relay.app, whose approval experience is the best-developed in the category.
  • You have engineering skill and want to self-host, especially around AI agents: n8n, with its tool-level gates.
  • You want a personal AI assistant that always asks first: Lindy’s per-action confirmation.
  • The work touches customers or money, and you need accountability — a record of who approved what: that’s the job HitLai was built for.

The category exists because trust, not capability, is now the constraint on automation. Any of these tools can pause for a human. The question worth asking before you pick one is what you’ll be able to say afterward: when a customer, a partner, or an auditor asks why something went out, the answer “a specific person reviewed it, here’s the record” is worth more than any feature list.
