Ditch Zapier. Own Your Automations.
A Zapier alternative for agencies that replaces brittle multi-step zaps with custom automation workflows running as code on your own hosting, connecting the platforms your clients rely on without task limits or per-action fees. Built properly, logged fully, and owned entirely by you.
No Task Limits, Ever
Your automations run as code on your own hosting. They process as many tasks as your workflows demand without a monthly cap or overage charge.
Handles Logic Zapier Cannot
Conditional branching, loops, retry logic, data transformation, multi-API chains, and complex scheduling, built properly in code.
Proper Error Logging
When something fails, you know exactly what failed, why, and where. Full logs with context, not a vague task history.
Full API Access
We use the complete API of every platform, not just the fields and triggers exposed in a pre-built connector. More control, better results.
You Own the Code
The automation is yours. You can extend it, audit it, hand it to another developer, and never worry about a platform changing its pricing model.
Built for Agency Scale
Reusable components, multi-client logic, and clean architecture that lets you deploy similar workflows for different clients efficiently.

How a Zapier Replacement Works With Us
We audit what you run today
We start with a short call to go through the zaps you rely on, the platforms they touch, and where they cost you money or break under load. No jargon and no commitment, just a clear read on what maps cleanly to code and what improves in the move.
We map it out and quote
We map each workflow properly: what triggers it, what data moves, and what should happen in the awkward cases most zaps ignore. You get a fixed-price proposal with a clear scope and timeline, so there are no surprises once we begin.
We rebuild it as code, one workflow at a time
We build against the live APIs in a staging environment, so we hit the same rate limits and quirks you will see in production. Each workflow is tested with messy, real-world data, ships with full logging, and goes live in sequence so nothing goes dark during the switch.
We launch it and keep it running
We deploy on your hosting with monitoring and alerting in place, so you know the moment anything stops flowing. You get documentation, the code itself, and optional ongoing support for when a provider changes their API, so the automation keeps working without you thinking about it.

Tell us which zaps you are running and we will come back with a fixed quote and a realistic timeline, usually within 2 working days. NDA first, no obligation.

Zapier Alternative FAQs
A Zapier Alternative for Agencies That Scales Without Task Limits
If you are looking for a way off Zapier, the questions worth asking are usually the same: what breaks first at scale, what the bill actually looks like once volume climbs, and whether the logic you need can be built properly rather than bolted together. Here is how we replace Zapier with automation you own.
Why agencies outgrow Zapier
Zapier is genuinely good for a single person automating a handful of low-volume tasks. The trouble starts when an agency runs dozens of workflows across multiple clients, because the pricing model charges per task, and every step of every zap counts. A five-step workflow firing a few hundred times a day quietly becomes your largest software bill.
The deeper problem is fragility. Multi-step zaps break on the one record that does not fit the template, and they tend to fail silently, so you find out when a client asks why their leads stopped arriving. You are also boxed in by whatever fields and triggers a connector chooses to expose, which is rarely the whole API.
At agency scale you need volume, control and visibility. Zapier gives you the first inch of all three and charges more the moment you want the rest.
What a custom Zapier replacement actually looks like
A custom replacement is not a like-for-like clone of your zaps in a different tool. It is the same outcomes, rebuilt as proper code that runs on your own hosting, triggered by webhooks, schedules or events, with each workflow doing exactly what it should and nothing it should not.
In practice that means the logic lives in one place you control, talks directly to the full API of every platform involved, and processes as many records as the work demands without a meter running. Most of this sits naturally alongside our wider business automation and API integration work, because a Zapier replacement is really both of those done deliberately.
We usually start by mapping your existing zaps, then rebuild them one workflow at a time so nothing goes dark during the switch.
The logic Zapier cannot handle
The workarounds tell the story. Anyone who has pushed Zapier hard has chained zaps together, bolted on a formatter step, or resorted to a code block to do something the interface would not. Those are all signs the work has outgrown the tool.
In code, the things people fight Zapier over become ordinary. Conditional branching that actually nests, loops over a set of records, retry logic with sensible backoff when an API is briefly down, data transformation between two systems that disagree on format, and calls chained across several APIs in one run. Scheduling can be as precise as you like rather than rounded to a plan tier.
None of this is exotic engineering. It is simply what you get when a workflow is written properly instead of assembled from boxes.
Not sure your Zapier setup can be replaced?
Send us the zaps you rely on and the platforms they touch. We will tell you honestly what maps cleanly to code, what improves in the process, and roughly what it would take.
Connecting the platforms your clients run on
We are deliberately platform agnostic, because agencies inherit whatever stack a client already uses. Day to day that means CRMs, marketing platforms, payment providers, accounting tools, ecommerce systems and bespoke internal software, often several at once inside a single workflow.
We work with the complete API of each platform rather than the slice a connector exposes, which is where custom builds pull ahead. Some of the connections we build most often have their own detail worth reading, including HubSpot and Salesforce. If a platform has an API, we can almost certainly connect it, and if it does not, there is usually still a route in.
The practical upshot is that one workflow can touch four systems and still behave as a single, reliable process rather than a chain of separate zaps hoping to stay in sync.
Error handling and knowing what failed
The biggest quiet cost of Zapier is not the price, it is the not knowing. A zap fails, the task log shows a red line with little context, and you are left guessing which record, which step and why.
When we build in code, failure is treated as a first-class case rather than an afterthought. Every run is logged with the data it handled, the step it reached and the exact error a platform returned. Transient failures retry on their own, and genuine problems raise an alert so you hear about it before a client does. You can look back and see precisely what moved and when.
That visibility is often the single biggest reason agencies are glad they switched. Reliability stops being a hope and becomes something you can check.
Ownership, cost and building at agency scale
A custom build costs more up front than a monthly Zapier plan, and it earns that back on anything high-volume or business-critical, because the per-task meter is gone and the workflow is yours. You can audit it, extend it, hand it to another developer, and never worry about a platform changing its pricing overnight.
For agencies the real leverage is reuse. We build with clean, reusable components so a workflow proven for one client becomes a fast starting point for the next, with per-client configuration rather than a rebuild each time. That same architecture underpins our white label API development, where the automation ships under your name.
You own the code and you own the process. The value compounds every time you deploy a similar workflow without paying for it again.
