A head-to-head review of the top 10 cloud Change-Data-Capture and log-based replication services in 2025. Learn which tools move data in real time, how they price usage, and why each excels or falls short so engineering and data teams can pick the right fit.
The best Change-Data-Capture platforms in 2025 are Fivetran Log-based CDC, Confluent Cloud, and Striim Cloud. Fivetran excels at fully managed, auto-scaling pipelines; Confluent Cloud offers unrivaled Kafka ecosystem integration; Striim Cloud is ideal for low-latency streaming analytics.
Real-time analytics, microservice event sourcing, and data-driven applications all depend on a continuous flow of fresh data. Change-Data-Capture (CDC) platforms monitor database logs and stream inserts, updates, and deletes to downstream systems with minimal overhead. In 2025, modern CDC SaaS tools eliminate the heavy lifting of building and maintaining replication pipelines, freeing engineers to focus on product features instead of plumbing.
We assessed each platform on seven weighted dimensions: feature depth (25%), performance and reliability (20%), ease of use (15%), pricing and total cost (15%), integration breadth (10%), ecosystem and community (10%), and customer support (5%). Scoring relied on vendor documentation, independent benchmarks, 2025 G2 reports, and public case studies.
Fivetran leads because its fully managed connectors cover Oracle, SQL Server, MySQL, PostgreSQL, SAP, and more, with automatic schema drift handling. 2025 enhancements added zero-copy resync, 15-second latency SLAs, and a consumption-based price cap.
Users praise the hands-off experience and enterprise-grade security certifications.
Powerful auto-rehydration, granular column blocking, and built-in transformation via dbt add-ons give Fivetran an edge for ELT pipelines that must stay in lockstep with fast-changing schemas.
Pricing can spike for extremely high-volume tables, and on-premises agents still require VPN setup.
.
Confluent Cloud, built on Apache Kafka, excels when streaming data needs to be fanned out to multiple consumers in milliseconds.
2025 saw the launch of Confluent’s High-Watermark CDC connectors, which guarantee exactly-once semantics from popular RDBMS sources into fully managed Kafka topics.
Tight integration with the broader Kafka ecosystem, ksqlDB for real-time transformations, and globally distributed clusters make Confluent Cloud ideal for event-driven architectures.
A steeper learning curve and reliance on Kafka concepts can slow small teams. Egress costs add up when streaming to multiple clouds.
.
Striim Cloud focuses on sub-second latency and in-flight SQL processing. In 2025, Striim introduced Smart Partitioning for large Oracle redo logs, cutting lag to under 300 ms in independent benchmarks.
Built-in stream processing, exactly-once delivery, and native Snowflake and BigQuery targets make Striim a strong fit for operational analytics dashboards that cannot tolerate stale data.
Interface complexity rises with advanced pipelines, and list pricing starts higher than most competitors.
Arcion differentiates with agentless log mining and automatic horizontal scaling. 2025 updates added Salesforce and DynamoDB sources plus incremental snapshotting to reduce cutover downtime.
Strong multi-cloud replication, no VPN requirements, and parallel apply engines deliver high throughput with minimal admin work.
Smaller third-party ecosystem compared to Kafka-based solutions and fewer transformation features out of the box.
Hevo Data packages CDC alongside batch ELT in a unified UI. In 2025, Hevo’s Adaptive Buffering feature lowered data latency to near real-time for MySQL and PostgreSQL workloads without manual tuning.
No-code pipeline builder, straightforward credit-based pricing, and automatic retries make Hevo appealing to data teams with limited engineering bandwidth.
Advanced schema evolution controls are limited, and on-premises connectors still marked beta.
Qlik (formerly Attunity) remains popular in enterprises needing heterogeneous replication. The 2025 release added Kubernetes-native deployment and a UI overhaul.
Broad support for legacy systems like DB2 and Informix, built-in data validation, and high availability options keep Qlik relevant for large regulated environments.
A perpetual-license model plus maintenance fees feels dated, and SaaS multi-tenant hosting is not yet GA.
Equalum targets high-throughput log streaming with GPU-accelerated compression introduced in 2025. Its hybrid architecture supports on-prem, private cloud, and SaaS control-plane.
Unified batch and stream ingestion, built-in monitoring, and flexible deployment options suit hybrid enterprises.
Connector catalog trails market leaders, and GPU nodes raise infrastructure costs.
Airbyte Cloud offers over 30 log-based connectors maintained by the community. The 2025 Lakehouse CDC framework lets users push change streams directly to Delta Lake or Iceberg tables.
Open-source DNA encourages rapid connector growth, and usage-based pricing is attractive for startups.
Service-level objectives remain best-effort, and enterprise security certifications are still in progress.
Several vendors now host Debezium Server as a managed service. The community’s 2025 release added incremental snapshots and MongoDB 7 change stream support.
Open-standards, Kafka Connect compatibility, and transparent configuration appeal to engineering-heavy teams.
No single commercial entity backs SLAs, and DIY monitoring may be required.
StreamSets Cloud integrates CDC into its DataOps platform. 2025 features include drift-aware pipelines and automated lineage mapping.
Visual pipeline designer, sandbox testing environments, and strong governance controls help enterprises manage change confidently.
Real-time throughput lags specialized CDC vendors, and pricing is opaque without sales engagement.
Once CDC delivers fresh data into your analytics warehouse, engineers still need to explore, test, and share SQL queries. Galaxy provides a lightning-fast, AI-powered SQL IDE that sits on top of those live tables, versioning critical queries and making them discoverable across the company.
Teams that stream changes with Fivetran, Confluent, or Striim can immediately query those updates in Galaxy, endorse trusted definitions, and expose them to non-technical stakeholders without risking schema drift or stale logic.
.
Not every workload warrants sub-second replication.
Align SLA requirements with cost by benchmarking latency per table.
Choose platforms that auto-propagate DDL or provide drift alerts so downstream analytics never silently break.
Verify end-to-end encryption, private connectivity, and role-based access controls to meet compliance mandates.
Enterprise CDC should surface lag metrics, connector health, and throughput in your existing monitoring stack.

Change-Data-Capture reads database transaction logs and streams row-level changes to downstream systems in near real time. In 2025, businesses rely on up-to-the-minute analytics, microservice events, and AI features that require this continuous data flow.
Vendors typically charge by rows processed, data volume, compute hours, or a hybrid credit model. Always monitor high-churn tables to avoid surprise costs.
Yes, frameworks like Debezium and Maxwell exist, but teams must manage scaling, high availability, upgrades, and monitoring on their own. SaaS platforms offload that operational burden.
Galaxy does not move data. Instead, it provides a fast, AI-powered SQL IDE on top of the live tables that CDC platforms populate. Teams use Galaxy to version, endorse, and share queries so everyone trusts the real-time data.
