Kortix vs Zapier: a hosted workflow tool, or the open-source system you own

If you are choosing a Zapier alternative, the decision comes down to the shape of the work. Zapier is the hosted automation incumbent, and it runs fixed, repeating workflows across thousands of apps well. Kortix is the open-source AI Operating System for the other kind of job: open-ended work whose path you describe in words and whose output a person should read before it lands.

What Zapier is good at

Zapier is a hosted workflow automation platform. You connect a trigger to one or more actions, and the Zap runs that sequence every time it fires. The catalog covers more than 9,000 apps, and the platform adds tables, forms and AI steps on top of the classic editor (Zapier workflows). It is a mature product, and for a fixed flow between mainstream apps it does that job well.

• The catalog is already built. Zapier lists 9,000+ apps and 66,000+ triggers and actions, so the system you need usually has a connector (Zapier).
• The editor is visual. You can build a Zap on a canvas or in code, and someone who is not an engineer can ship a working one (Zapier workflows).
• Zapier runs the hosting. There is nothing to deploy or maintain, because your Zaps run on Zapier's cloud while you work (Zapier).
• IT gets the controls it asks for. Zapier advertises SOC 2 Type II and SOC 3, SAML single sign-on with SCIM provisioning, action restrictions and managed connections (Zapier).

Where Zapier stops for open-ended work

• A Zap runs the steps you listed. Every step is fixed in advance, so a job whose path you cannot draw has to be worked out by a person first.
• Work is priced per task. Zapier bills per task, and each successful action in a Zap counts as one, which makes a long or unpredictable run harder to forecast (Zapier pricing).
• The workflow lives in Zapier. Your Zaps stay inside your Zapier account, held as data in Zapier's product.
• It runs in one place. You use Zapier through its app or its API on Zapier's cloud, so there is no copy of the platform to install on your own servers.

None of that is a flaw in the product Zapier set out to build. It is a hosted automation platform, and it is good at being one.

What Kortix is

Kortix is for the work on the other side of that line. Your agents, their skills, your company memory, and every connector live as files in one git repo you own, so the whole system is text a team can read, diff and roll back (Kortix docs).

The unit of work is a session. Each session has its own isolated machine and branch, and the agent plans its own steps on that machine (Kortix docs). Session work reaches main through a change request. Merge is default-deny for agents, so a person reads the change as a diff before it lands (Kortix on GitHub).

Kortix connects to 3,000+ apps in a click, plus MCP, OpenAPI, Postman, GraphQL and raw HTTP. Connector credentials are brokered server-side and never enter the machine, and each tool call can be set to allow, ask or block (Kortix on GitHub). You choose any model provider with your own keys, or the ChatGPT plan you already pay for (Kortix docs).

Running a Zapier-style job on Kortix

A schedule or a webhook can start a Kortix session with no person present, so the clockwork side of automation still works. When it fires, the agent does the job on its own machine and opens a change request with the result.

triggers:
  - slug: daily-digest
    type: cron
    cron: '0 9 * * 1-5'
    prompt: Summarize yesterday's support tickets and open a change request with the digest.

Approval gates you set. Off until you set them. A step that sends or writes can wait for a person before it runs (Kortix docs). Because the company is one repo, the memory an agent builds and the rules that scope it live beside the code as files you own.

Kortix runs on Kortix Cloud, in your VPC, or on your own on-prem network, and self-host is free (Kortix on GitHub). Free is $0 with 200 credits per month and 1 project; the team plan is $40 per seat per month with 2,500 credits per month per seat, pooled (Kortix pricing).

Where Zapier is still the better pick

If your work is a fixed flow between mainstream apps, and you want someone else to run the infrastructure, Zapier is the better pick. It is hosted, its catalog is larger, and its free plan covers 100 tasks a month to try it (Zapier pricing). For a team that wants a repeating trigger-and-action sequence with no repo and no machine to manage, Zapier asks less of you than we would.

Kortix and Zapier side by side

When to pick which

Pick Zapier when the job is a fixed flow: the same steps, in the same order, on a schedule or a webhook, with a connector for each app already built. It is the simpler choice for deterministic automation, and someone else runs it.

Pick Kortix when the job is open-ended: research, a report, a fix, a campaign, work whose steps you cannot list in advance and whose output a person should approve. Kortix gives that work a real machine, the company's tools and memory, and one repo that holds the whole configuration. Teams that run both kinds of work keep the hosted tool for the clockwork and give the rest to Kortix.
