our call
Start with RudderStack — 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.
RudderStack
Ingesting JSON events to a database takes a weekend, but building a production CDP requires maintaining SDKs for 10+ platforms and continuous integration APIs for 200+ destinations. Third-party API changes, rate limits, schema evolutions, and dead-letter queues render custom replacements a constant maintenance nightmare.
you can rebuild
- Simple web track/page event capturing via browser JS
- Webhook ingestion proxy
- Direct raw JSON dumps to ClickHouse or Snowflake
- Basic server-side HTTP event forwarding
- Static property enrichment on event payload
what you lose
- 200+ pre-built integration connectors for downstream tools
- Maintained iOS, Android, React Native, and web client SDKs
- Visual pipeline transformation IDE with user sandboxing
- Automated retry mechanisms, backoff queues, and dead-letter management
- Enterprise identity resolution and user identity graph construction
real moats
- Ecosystem coverage across hundreds of destination APIs and their frequent schema updates
- Engineered fault tolerance handling billions of peak events per day with zero data loss
- Security attestations (SOC2 Type II, HIPAA, ISO27001) required for enterprise pipeline compliance
open source escape hatches
- RudderStack Server SSPL
- Jitsu MIT
- Vector by Datadog MPL-2.0
