The verdict
NOT REALLY — THE UI ISN'T THE MOAT
Celonis is not something you clone with an LLM prompt. At $100,000+ per year, enterprises are paying for deep database connectors into legacy SAP, Oracle, and Salesforce schemas, transactional event-log parsing algorithms, real-time process graph visualizations, and corporate governance compliance. While an AI agent can build a basic Alpha Algorithm or Heuristic Miner in Python to transform an event log into a Directed Acyclic Graph (DAG), the actual engineering burden lies in SAP table extraction, memory-efficient process graph rendering for millions of cases, and operational enterprise security. Building an internal process graph parser for clean event logs takes weeks, but replacing Celonis's connector ecosystem and enterprise trust is practically impossible for a small team.

The one-shot build prompt
Build an event log process mining web application in Python and React. The backend must use FastAPI and PM4Py.
Data Model:
1. EventLog: id, name, uploaded_at.
2. EventRecord: case_id (string), activity_name (string), timestamp (datetime), resource (string, optional), attributes (JSON string).
3. ProcessGraph: nodes (activity names, execution counts), edges (source, target, frequency, average_duration_seconds).
Backend Core:
- Provide an API endpoint POST /api/v1/upload-csv that accepts a CSV containing case_id, activity, timestamp columns.
- Parse the CSV into Pandas, convert timestamps, and format into a PM4Py EventLog object.
- Implement GET /api/v1/process-map/{log_id} that generates a Directly-Follows Graph (DFG) using PM4Py. Calculate total case counts per node and throughput times (average and median) for each edge transition between activities.
- Implement GET /api/v1/bottlenecks/{log_id} returning the top 5 longest edge transitions based on throughput time.
- Implement GET /api/v1/variant-analysis/{log_id} returning the distinct activity sequences (variants) ordered by occurrence frequency, along with the percentage of total cases each variant represents.
Frontend Core:
- Build a dashboard using React and Cytoscape.js or React Flow to render the process map interactively.
- Nodes must display the activity name and hit count. Edge thickness should scale with transition frequency.
- Clicking an edge reveals average throughput duration and case drop-off statistics in a side panel.
- Add a slider control to filter out low-frequency edges (e.g., show top 10% to 100% of paths) to reduce visual graph clutter.
- Provide a variant selector table that filters the main process map visualizer to highlight only the selected execution variant.
Out of Scope:
- SAP ABAP extraction scripts or direct database connectors.
- Real-time streaming log ingestion.
- Action Engine / automated task execution workflows.
- User management, authentication, or SSO.$ each button prefixes agent-specific run instructions · build your own product, never copy proprietary code, trademarks or designs
Scorecard
What you can actually replace
- ✓CSV/Parquet event log ingestion and parsing.
- ✓Directly-Follows Graph (DFG) generation and interactive process map visualizations.
- ✓Process variant frequency analysis and coverage metrics.
- ✓Basic throughput and bottleneck detection between sequential activities.
- ✓Custom filter creation based on case attributes or time windows.
What you lose
- ×Pre-packaged SAP/Oracle connectors that handle complex relational table joining into event logs automatically.
- ×Process Query Language (PQL), Celonis's custom query engine optimized for process analytics.
- ×Real-time Action Engine automations that trigger downstream ERP actions upon detecting workflow anomalies.
- ×Pre-configured benchmark models for standard enterprise workflows (Procure-to-Pay, Accounts Payable, Order-to-Cash).
- ×Enterprise governance, access control granularities, and compliance guarantees.
Why people still pay — the real moats
Moats
- — Deep, battle-tested connectors for SAP (ABAP/ECC/S4HANA), Oracle, and Salesforce legacy database schemas.
- — A proprietary in-memory process query engine (PQL) optimized for process graph analytics.
- — Pre-built domain logic, KPI frameworks, and operational playbooks for standard enterprise workflows (Order-to-Cash, Procure-to-Pay).
- — Enterprise trust, compliance certifications, and vendor procurement clearance.
Hard parts
- — Generating process graphs from billions of unstructured log events without dynamic memory crashes.
- — Extracting clean relational event logs (Case ID, Activity, Timestamp) out of complex SAP relational schemas spanning dozens of joined tables.
- — Executing real-time Process Query Language (PQL) queries over distributed petabyte-scale event datasets.
- — Maintaining custom ABAP scripts and legacy database connectors across client SAP upgrade cycles.
- — Managing huge compute costs when executing graph reconstruction on multi-gigabyte event logs.
- — Providing enterprise-grade security, SOC2 Type II, ISO 27001, and strictly isolated multi-tenant data processing pipelines.
Build this instead
Shopify/ERP Event Stream Bottleneck Analyzer
Instead of extracting SAP relational tables, ingest ERP event Webhooks (PostgreSQL/BigQuery) and surface process friction strictly for order-to-cash lifecycle bottlenecks.
WMS Logistics Process Graph Engine
A lightweight tool that ingests warehouse management systems (WMS) log streams to calculate actual picking and packing cycle time variance per SKU family.
Automated Accounts Payable Exception Mining
An automated auditor that cross-references purchase order line items against receiving logs and vendor invoices to highlight duplicate payments and missing discounts.
Prior art — do not start from zero

FAQ
+Can I really replace Celonis with an AI-generated app?
NOT REALLY — PROCESS MINING IS AN INTEGRATION AND MEMORY GRAPH PROBLEM. An AI prompt can easily generate a simple process visualizer using open-source Python libraries like PM4Py. However, Celonis's real product is its deep connector architecture into legacy ERPs like SAP, custom process query engine (PQL), and enterprise execution capabilities. An MVP takes roughly 4-6 weeks; matching the product properly is closer to 24+ months.
+How long does it take to rebuild Celonis?
A usable internal version: 4-6 weeks. A version you would sell or bet a business on: 24+ months, mostly spent on generating process graphs from billions of unstructured log events without dynamic memory crashes..
+What do you actually lose by leaving Celonis?
Pre-packaged SAP/Oracle connectors that handle complex relational table joining into event logs automatically. Process Query Language (PQL), Celonis's custom query engine optimized for process analytics. Real-time Action Engine automations that trigger downstream ERP actions upon detecting workflow anomalies.
+Is it legal to build a Celonis alternative?
Building a competing product with your own code is normal competition. Copying their code, trademarks, brand assets or scraping their platform is not. Use the prompt to build your own implementation of common features.
