Celonis vs SiteSpect
Celonis ($15,000/mo/mo, vibe code 4/10) vs SiteSpect ($6,000/mo/mo, vibe code 3/10). SiteSpect is the easier one to rebuild yourself — here is what you lose either way.

our call
Start with SiteSpect — highest vibe code, weakest moat.
Celonis
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.
you can rebuild
- 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.
real 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.
SiteSpect
Basic client-side A/B testing is trivial, but SiteSpect's core value is tagless server-side DOM manipulation via reverse-proxy network routing. Rebuilding edge-layer HTTP stream rewriting with sub-millisecond latency and continuous statistical confidence calculations requires deep systems engineering, not just web app code.
you can rebuild
- Basic client-side feature flagging and traffic split percentages
- Dashboard UI for viewing conversion funnels and experiment metrics
- User segmentation based on simple browser cookies and query params
- Basic event tracking and goal conversion logging
- Simple visual overlay and variant creator for frontend DOM tweaks
what you lose
- Tagless HTTP response stream modification at the reverse proxy layer
- Zero-layout-shift (CLS) rendering of A/B test variations
- Advanced enterprise bot filtering and automated traffic sanitization
- Sequential analysis statistical engine for real-time significance calculation
- Multi-armed bandit traffic routing and automated auto-allocation

Questions people ask
Which is easier to rebuild with AI, Celonis or SiteSpect?
SiteSpect. It scores 3/10 on vibe code with a moat of 5/10, so an AI-assisted MVP takes about 2 weeks and a full replacement about 12-18 months, due to low-latency edge proxy architecture and multi-variant stats infrastructure.
Which one costs less, Celonis or SiteSpect?
SiteSpect at $6,000/mo/mo for a typical mid-market store. The gap between the two is about $108,000/mo a year.
What do I lose if I replace 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.
