A Zapier alternative that runs on your own accounts.
If you're outgrowing Zapier, here's why teams switch to Writ - and exactly how to move without losing what's working.
Zapier runs on zapier's cloud, through each app's official api. Writ runs on your accounts, and makes every workflow a REST API and an MCP tool.
The largest no-code automation hub, connecting thousands of apps through their official APIs with triggers and actions.
What sends people looking for a Zapier alternative
These are the reasons teams tell us they move. We name where Zapier is still the better tool further down - switching should be an honest decision.
- ✓The site or internal tool you need to automate has no public API, so Writ acts in the browser instead.
- ✓You need authenticated, in-browser actions on your own accounts, callable as an API and MCP tool.
What Writ adds on top
The synthesis position: the four things that most often make the switch worth it.
Writ and Zapier, side by side
The structural differences: billing unit, where runs execute, auth, MCP, marketplace. Reviewed June 2026.
| Criterion | Writ | Zapier |
|---|---|---|
| Works on sites with no API | Yes, that is the core wedge; act in the browser when there is no API | No: requires an app to have an API integration |
| Login + 2FA on the hard web | Personas with built-in 2FA on your own authorized accounts | Handled by each app's OAuth, not arbitrary sites |
| MCP-native | Every workflow publishes as an MCP tool | Limited |
| Run on your own machine | Yes: local agent, no compute charge, reaches intranet systems | No |
| Billing unit | Actual cloud running time; free on your own machine | Per task |
Moving from Zapier, step by step
Start small, prove it, then port the rest. You never have to switch everything at once.
- 1
Pick one Zapier job to move
Start with a single workflow - the one that costs the most or breaks the most on Zapier. A small first move de-risks the switch.
- 2
Rebuild it once in Writ
Record the flow in the browser recorder, describe it to an AI session, or discover the site's own API - whichever fits. You get a real, replayable workflow.
- 3
Call it as an API and MCP tool
Publish the workflow to get a REST endpoint at /v1/{slug}/{path} and an MCP tool, authenticated with a wt_ key.
- 4
Run it your way and compare
Run it free on your own machine or on metered cloud, watch the success rate, then port the rest of your Zapier work at your own pace.
Keep what works. You can run Writ alongside Zapier. Use Zapier where it shines and add Writ for the parts it can't reach - sites with no API, authenticated in-browser actions, and any-site MCP tools. See the full comparison ▸

Zapier is genuinely good at this.

- —Deep ecosystem, templates, and documentation.
Stay on Zapier if
- —The apps you want to connect already expose official APIs that Zapier supports.
- —You want the broadest catalog of no-code app-to-app integrations.
