Comparison
Dagster and Apache NiFi both land on Depends.
Buy it if you have a real data engineering team building Python pipelines that need lineage, observability, and scheduling.
Buy if you have dedicated data/platform engineers moving high-volume data between many systems . it's free and reviewers say it fills a niche nothing else covers.
| Compare | Dagster | Apache NiFi |
|---|---|---|
| Verdict | Depends | Depends |
| Best for | Python-savvy data engineering teams | Data engineering teams moving high-volume streams |
| Who it's not for | Small teams that just need scheduled scripts . use cron | Small teams needing simple point-to-point data sync |
| Privacy | Published security page with SSO/RBAC/audit logging; one disclosed 2025 local-file-inclusion CVE in the gRPC server.⁵ | Ongoing security burden: 57 tracked CVEs including recent auth-bypass and privilege-escalation flaws; harden before exposing anything. |
| Support quality | No support evidence in sources | Community-driven; commercial support pricing hard to find |
| Public sentiment | Practitioners praise the asset-centric model and local developer experience, with little complaint volume in public sources.⁴ | Users praise its visual, powerful dataflow handling but find it complicated, with governance and lifecycle concerns.13 |
| Biggest gotcha | Dagster is joining Prefect; expect product, roadmap, and possibly pricing changes during integration³ | Free software isn't free total cost: clustering, security hardening, and support carry real expense15 |
