## TL;DR

Erathos delivers managed ingestion with table-level control and per-run observability, without turning into an engineering project. Airbyte leads in catalog size (600+) and open-source flexibility, but the OSS “free” tier costs infrastructure plus engineering time (Kubernetes/DevOps) and carries the risk of silent failures. Choose Erathos for managed, reliable operation; choose Airbyte for full self-host control and a broad catalog.

## You should choose Erathos when:

- You want managed ingestion instead of self-hosting, without Kubernetes, DevOps, or hidden infrastructure costs.
- You value table-level control and native alerts over the risk of silent failure.
- You use Brazilian sources and want pt-BR support.
- You want more control without the operational overhead.

## You should choose Airbyte when:

- You have a technical team already running Kubernetes and want full self-host control (OSS is unbeatable on flexibility).
- You need a large number of international SaaS sources (600+).
- You want a custom connector for any source (Connector Builder / CDK).
- You prioritize the AI-native / Context Store narrative.

## Why Erathos is the best alternative for your business?

| Features | Erathos | Airbyte |

| Custom backfill | ✓ Filtered, no full re-sync required | ~ Reset/refresh of the entire connection |
| Block window | ✓ Native | ✗ Not available |
| Custom retry | ✓ Customizable per connection and job | ~ Not customizable per connection |
| Sync frequency | 5 min (Pro/Enterprise) | 1 h (Cloud) |
| Run history | ✓ Complete, without having to dig through logs | ✓ Sync history |
| Freshness indicator | ✓ Per table/endpoint | ~ Depends on configuration |
| Alerts | ✓ Slack, Discord, email, and webhook | ~ Failure via webhook/email (you configure the destination) |
| Managed | ✓ Fully managed with auto-scaling | ~ Cloud is managed; OSS is self-hosted |

| Support | ✓ English and Portuguese (Brazilian) | Community and tickets, in English |

## Control

On Erathos you configure ingestion behavior per table/endpoint (retry, custom backfill, block window), all managed for you. Airbyte OSS gives you full flexibility because you own the code, but that comes with Kubernetes, connector maintenance, and the risk of silent changes. Erathos’s fine-grained control doesn’t cost you an engineering project.

## Observability

Erathos shows run history, per-table freshness, and fires error and inconsistency alerts to email, Slack, or Discord — no need to dig through logs. On Airbyte, visibility depends on your own observability stack and configuration, and community connectors can fail silently.

## Pricing

Erathos charges per row, predictably. Airbyte OSS is free, but you pay for the infrastructure to run it (often $500 to $3,000+/month) plus 20 to 40 hours/month of engineering time; Airbyte Cloud charges by volume (rows or GB). The real cost of open source is rarely zero.

## Connectors

Airbyte has the largest catalog (600+), but only about 15% of sources are Airbyte Managed, and the rest are Marketplace/community-maintained, with variable quality and connectors the documentation itself recommends using with caution in production. Erathos has 100+ maintained, production-ready connectors, including native BR sources that on Airbyte would be an internal engineering project.

## Reliability

Erathos maintains a 98% run success rate and has its own failure-detection and error-correction mechanism: when something goes off script, the problem is handled before it becomes bad data downstream. On Airbyte, only about 15% of sources are maintained by Airbyte itself, and the rest are community-maintained. When one of those connectors breaks, in practice you’re left opening a ticket, waiting on the community, or fixing the code yourself.

## Frequently Asked Questions

### What’s the difference between Erathos and Airbyte?

Erathos is managed ingestion with table-level control and per-run observability, production-ready with no maintenance required. Airbyte is open-source, with the largest connector catalog and full flexibility, at the cost of self-hosting (Kubernetes/DevOps) or Airbyte Cloud, and with variable quality across community connectors.

### How does Erathos’s pricing compare to Airbyte’s?

Erathos charges per row, predictably. Airbyte OSS is free, but you pay for the infrastructure to run it (often $500 to $3,000+/month) plus engineering hours; Airbyte Cloud charges by volume (rows or GB). The real cost of open source is rarely zero.

### Does Erathos support CDC?

Yes, Erathos launched CDC for Postgres, with expansion underway. Airbyte also offers CDC (via Debezium), but with known limitations: schema changes require a re-sync, and column changes aren’t replicated automatically.

### Does Erathos have the connectors I need?

Erathos has 100+ maintained, production-ready connectors, including native Brazilian sources (Bling, Omie, RD Station). Our custom connector feature is also in development and will be available soon. Airbyte has 600+, but only about 15% are Airbyte Managed; the rest are community-maintained, with variable quality and upkeep. Keep in mind Erathos can build the connector you need through a request on the platform itself.

### Is it worth migrating from Airbyte to Erathos?

It makes sense if you want to stop maintaining infrastructure and connectors and want managed observability and support. If your team already runs Kubernetes, wants full control of the code, doesn’t mind spending hours maintaining infrastructure, and needs a huge catalog of international sources, Airbyte OSS is still a strong choice.
