The Zapier alternative with an AI builder

Looking for a Zapier alternative? MadMax builds the workflow from a plain-English description, tests every step on real data, and adds human approvals.

People go looking for a Zapier alternative for a few familiar reasons. The per-task bill grows faster than the value, especially once a zap polls often or runs a multi-step chain where each action counts. Logic that should be simple (a branch, a loop over a list, "wait for someone to say yes") turns into a stack of Paths, Filters, and Formatter steps. And testing means turning the zap on and watching, fine for a two-step bridge, nerve-wracking for anything that emails a customer.

MadMax takes a different route: you describe the outcome in a sentence, the AI plans and builds the workflow on a canvas, then runs every step against your real data before you turn it on.

Where MadMax is different

The AI builds it, then proves it. Type "every morning, fetch the top posts from r/SaaS and Slack me a summary" and Max proposes a plan, lays the graph on the canvas, and runs a verification pass. Read-safe steps execute on realistic inputs, triggers capture a real sample, and anything that would send is previewed byte-for-byte without sending. See how verification works.

Approvals are a step, not a workaround. Drop an approval step anywhere and the run pauses until a person decides, in Slack, by a one-click email link, by texting YES or NO, or from the run's page. The run continues down the approved or rejected port.

Real branching and loops on a canvas. If, switch, loop, loop until, and merge are nodes with their own ports. A loop runs its body once per item and fires done with the collected results.

AI agent steps with knowledge and memory. One AI agent tile covers extract, classify, summarize, and custom prompts with structured output. A custom-prompt agent can hold tools (web, browser, code, your connected apps), a knowledge base, and an AI memory that remembers prior turns across runs.

Every run is inspectable per step. The run detail shows each step's input, output, error, timing, and attempt count, and a failed step carries a "Repair with AI" link. Run history is kept, not pruned.

Email and SMS are built-in triggers. Each workflow can mint its own inbound email address, and verified phones can text the MadMax number to start a run. No third-party mailbox parser needed.

MCP and REST for AI clients. The in-canvas assistant's tools are exposed over MCP, so Claude Desktop, Cursor, or Claude Code can build and verify workflows for you. The REST API covers workflows, runs, stores, and knowledge bases.

Pricing shape. Free is a personal workspace with 3 active workflows, 500 runs a month, and 100 AI credits to start. Pro is $29 per month per workspace: unlimited workflows, 2,000 runs a month, 10 runs in parallel, 5 seats, 1,000 AI credits monthly, and top-ups that never expire. There is no per-task line on the bill.

Where Zapier is still the better choice

  • Catalog breadth. Zapier connects to thousands of apps. MadMax ships native integrations for the apps teams use most (Slack, Gmail, GitHub, Notion, Stripe, Postgres and more) plus HTTP and webhooks for anything with an API. If your automation depends on a long-tail SaaS app with no public API, Zapier likely has it and MadMax does not.
  • Two-step bridges. For "new row in a sheet, send a Slack message," Zapier's form editor is the fastest path there is, and non-technical teams already know it.
  • No AI in the loop. If you want to click through a trigger and an action yourself with no model involved, Zapier's editor is built for that.

Moving from Zapier

A migration is a list, not a project.

  1. List your zaps and mark the ones that still matter.
  2. For each live zap, describe what it does to MadMax in one plain sentence. Max builds it and starts verifying.
  3. Connect the accounts it asks for (Slack, Gmail, Google Sheets). Those are the only pauses.
  4. Read the previews when verification finishes: the exact message a send would have produced.
  5. Activate, and run both for a week on the same schedule or webhook. Compare the output.
  6. Turn the zap off.

Start with the zap you trust least. That is where per-step test runs pay off first.

Frequently asked

Is there a free Zapier alternative? MadMax has a free plan: a personal workspace, 3 active workflows, 500 runs a month, and the full integration library. No card required.

Can I self-host MadMax? No. MadMax is a managed service. Enterprise customers get a dedicated, tenant-isolated deployment on their own database and infrastructure.

Does it work with Slack and Gmail? Yes. Both are native OAuth connections, and Max wires them into steps for you. Approvals can post Approve and Reject buttons straight into Slack.

What happens when a step fails? By default the run fails and the run page shows the step, its input, and the error. Per step you can choose retry (up to 5 attempts with backoff), continue out an error port, or retry then continue. See error handling.

Can I bring my own OpenAI or Anthropic key? Yes, for AI steps inside workflows. Connect Anthropic, OpenAI, Gemini, or OpenRouter in Settings and bind it on the agent step; usage bills to your key. The builder chat itself always runs on the MadMax platform model.
