Activepieces + Ertas

Build intelligent automation workflows on Activepieces using Ertas-trained models for self-hosted, privacy-first AI processing at every step.

Overview

Activepieces is an open-source automation platform that provides a visual workflow builder for connecting applications and automating business processes. Like commercial alternatives such as Zapier and Make, Activepieces offers a trigger-action model with hundreds of pre-built connectors. What distinguishes it is the self-hosted deployment model: organizations can run Activepieces on their own infrastructure, ensuring that all data flowing through automated workflows stays within their network perimeter.

This self-hosted architecture makes Activepieces a natural fit for organizations that need AI automation but cannot send data to third-party services. When combined with locally deployed Ertas-trained models, the entire automation pipeline — trigger, AI processing, and action — runs within the organization's infrastructure. No email content, customer data, or business documents leave the network at any point. That matters most in healthcare, legal and finance, where data protection rules often keep sensitive workflows off cloud-based AI automation platforms.

How Ertas Integrates

Ertas-trained models connect to Activepieces through its HTTP request piece or custom code pieces. After deploying your fine-tuned model via Ollama or any OpenAI-compatible server on your internal network, you add an HTTP POST step in your Activepieces flow that calls the model's chat completions endpoint. Because both Activepieces and the inference server run on your infrastructure, the AI call is a local network request — fast, free, and completely private.

The Ertas-Activepieces stack creates a fully self-hosted AI automation platform. Consider a legal firm that needs to automatically classify incoming case documents, extract key entities, and route them to the appropriate practice group. With Activepieces watching an email inbox or file share for new documents, an Ertas-trained legal model processing each document for classification and extraction, and Activepieces routing the results to the correct team channel — the entire workflow runs on premises with zero external API calls. The firm can inspect every step of the flow and set its own data retention, and the documents it processes never pass through an outside AI provider. This same pattern applies to healthcare organizations processing referrals, financial firms classifying transactions, and any organization that needs intelligent automation over sensitive data.

Getting Started

1
Fine-tune a model in Ertas Studio
Train a model on your specific automation task — document classification, entity extraction, content generation, or text analysis.
2
Deploy both Activepieces and your model on-premise
Run Activepieces via Docker on your infrastructure. Deploy your Ertas-trained model through Ollama on the same network for low-latency, private inference.
3
Create a flow with your trigger
Build an Activepieces flow starting with your trigger — new email, file upload, webhook, scheduled task, or any supported event source.
4
Add an HTTP request step for AI processing
Add an HTTP request piece that POSTs to your local model endpoint. Structure the request body as an OpenAI-compatible chat completion call with the trigger data.
5
Route results to downstream actions
Use the model's response to drive subsequent flow steps — route documents, update databases, send notifications, or trigger additional processing.
