# Reliable ETL Software for Auto-Healing, Fault-Tolerant Pipelines

Hevo's reliability engine keeps pipelines self-healing and fault-tolerant — detecting and resolving issues automatically, verifying data batches before load, and absorbing source data spikes without manual intervention or downtime.

## Key facts

- Rated 4.4/5 on G2 (290+ reviews).
- Used by 2,000+ data teams.
- SLA-backed uptime with fault-tolerant architecture.
- Ingests and processes billions of records through distributed pipelines.

## Self-healing and fault tolerance

- **Self-recovery:** automatic detection and repair of ETL pipeline issues, retrying failed tasks and restoring normal data flow without manual intervention.
- **Batch-level verification:** each data batch is checked for completeness, accuracy, and consistency before loading, preventing partial or incorrect data from reaching analytics.
- **Scale without impact:** absorbs spikes in source data smoothly while keeping both source and target performance stable.
- **Fail-safe architecture:** failures are detected, isolated, and recovered automatically, while preserving data accuracy, completeness, and availability.

## Visibility and monitoring

- **Pipeline monitoring dashboard:** data flow volume, latency, and pipeline health in one place, so issues are spotted and resolved before they impact downstream analytics.
- **Smart alerts:** intelligent alerts inform you what happened after issues are already handled in the background.
- **Activity logs:** every operation, change, and retry captured with precise timestamps, to speed up troubleshooting and strengthen audit confidence.
- **Session logs:** full data journeys traced at a granular level, for issue detection, behavior validation, and complete pipeline observability.

## Built for scale

- **High throughput:** billions of records ingested and processed via distributed pipelines engineered for low latency and consistent performance.
- **Auto scaling:** pipelines scale dynamically with data volume, so bursts and spikes never overload sources or slow downstream delivery.
- **Enterprise-grade reliability:** SLA-backed uptime and fault-tolerant architecture keep mission-critical data flowing without interruption.

## What customers say

- **Prasanth Narayan, Senior Data Engineer, Collectors:** "The biggest benefit after switching to Hevo was broader, reliable replication support. We replaced Stitch's gaps and community plugins, migrating 99% of integrations smoothly."
- **Juan Ramos, Analytics Engineer, Ebury:** "We needed highly reliable, high performance pipelines. After facing bugs, limited support, and high costs with Fivetran, we switched to Hevo for dependable, scalable data movement."
- **Prudhvi Vasa, Head of Data, Postman:** "Hevo offers broad, up to date integrations with strong reliability. The platform is easy to use, and the team is highly responsive, making it a consistently great experience."
