Introduction
Airbyte is a data integration platform. It is known for a large catalog of connectors, most of them built and maintained by its community. It is source-available and runs on Kubernetes or as a hosted service. Filament is an open-source replication engine that moves data into the systems you already run, verifies every batch it writes, and resumes where it left off when a run fails.

Self-hosted in full.
Yes. One repository, no paid tier, nothing gated.
Core edition only. Single user, one workspace, no RBAC, no SSO, Slack-only support. Self-Managed Enterprise is no longer sold.

Adding a new source
A YAML manifest for REST APIs, loaded at runtime with no rebuild. A Go driver for databases and other driver-based sources.
Connector Builder UI or low-code YAML, packaged as its own Docker image. Python CDK or Kotlin Bulk CDK for the rest.

Connector maintenance
Every connector lives in the engine repository with a published maturity level (alpha, beta, stable).
59 certified sources maintained by Airbyte. 535 marketplace sources maintained by the community with no SLA. 6 enterprise sources, maintained by Airbyte, cost extra.

Services to operate
Server and control plane, with Postgres and NATS. Each run is its own Kubernetes Job. One binary for evaluation.
10 services enabled by default in the Helm chart (server, worker, workload launcher, workload API, Temporal, cron, manifest server, bootloader, Postgres, MinIO), plus a pod per sync.

Runtime
Static Go binaries on distroless images. One runner code path wherever a run executes.
Java 21 and Kotlin platform. Python or Java connectors. Every sync launches a pod with separate source, destination, and orchestrator containers.

Scheduling
Built-in cron per pipeline. Safe to run multiple control planes.
Built-in on Temporal. Schedule accuracy documented as plus or minus 30 minutes.

SaaS source execution
Manifests interpreted inside the engine, in the same process as the run. No per-connector containers.
One container per source per sync. YAML connectors run inside a Python declarative runtime image.

Embeddable
Yes. Go library (app.Run) with swappable event bus, state store, and secrets.
PyAirbyte runs connectors from Python, with no scheduling, orchestration, or alerting.

Correctness
Resume after failure
Mid-table, from per-shard checkpoints, for upsert, incremental, and CDC runs. A failed run lands in a partial state and continues on re-request.
Resumable full refresh from an artificial cursor on Postgres, MySQL, MSSQL, Mongo, and Python CDK sources, when the destination supports refreshes. Other sources restart the stream.

Per-batch integrity check
CRC32-C computed independently on the read side and the write side of every batch. A mismatch fails the run.
Record counts compared per state message. A mismatch is logged, not failed, unless a feature flag is switched on. No checksum.

Change data capture
Native. Postgres logical replication (pgoutput) with a consistent snapshot bootstrap. MySQL binlog with GTID cursors.
Embedded Debezium for Postgres, MySQL, MSSQL, MongoDB. Oracle, SAP HANA, and Db2 CDC are enterprise connectors.

Schema drift
New columns added to the destination automatically. Add-only, nothing dropped, nothing rewritten.
New columns propagate. A type change writes row errors until you refresh the schema and refresh the stream.

Parallel reads within a table
Yes. Large tables split into up to 64 shards (keyset, bitmap, or ctid) read concurrently.
Socket mode on Bulk CDK database sources, concurrency defaulting to 1. Socket mode is enabled today only for the MySQL source.

Row lineage
Every replicated row carries the run id and start time. CDC rows also carry operation, source position, and sequence.
_airbyte_raw_id, _airbyte_extracted_at, and _airbyte_meta per row.

Cost
What drives billing
Nothing. Compute you already run.
Cloud: credits at $2.50 each. APIs and custom sources bill $15 per million rows. Databases and files bill $10 per GB of serialized records. Pro and Enterprise Flex bill on Data Worker capacity.

Paid tiers
None.
RBAC, SSO, and multiple workspaces are Pro or Enterprise Flex. 15-minute syncs start at Cloud Plus. Typing and deduplication add warehouse compute.
