# Sources Overview

> Connectors Filament can read from.

Filament ships eight source connectors today: two native database
connectors, five manifest-driven SaaS connectors sharing one implementation,
and a synthetic generator for testing.

## Databases

| Source                                           | Package                      | Notes                                                                       |
| ------------------------------------------------ | ---------------------------- | --------------------------------------------------------------------------- |
| [PostgreSQL](/pages/connectors/sources/postgres) | `connectors/postgres/source` | Adaptive read-mode routing (keyset, bitmap, ctid); full + incremental + CDC |
| [MySQL](/pages/connectors/sources/mysql)         | `connectors/mysql/source`    | Keyset reads plus GTID-based CDC                                            |

## SaaS Apps

All five run on the same [HTTP](/pages/connectors/sources/http) connector,
configured by a declarative manifest rather than by their own Go package:

| Source                                     | Manifest      | Notes                                                       |
| ------------------------------------------ | ------------- | ----------------------------------------------------------- |
| [Attio](/pages/connectors/sources/attio)   | `attio.yaml`  | 23 resources — the deepest parent/child nesting of the five |
| [GitHub](/pages/connectors/sources/github) | `github.yaml` | Repositories, issues, pull requests for one organization    |
| [Linear](/pages/connectors/sources/linear) | `linear.yaml` | The one GraphQL manifest — everything else is REST          |
| [Notion](/pages/connectors/sources/notion) | `notion.yaml` | Databases, pages, blocks                                    |
| [Slack](/pages/connectors/sources/slack)   | `slack.yaml`  | The only bundled manifest with incremental sync             |

## Custom & Testing

| Source                                     | Package             | Notes                                                                                                  |
| ------------------------------------------ | ------------------- | ------------------------------------------------------------------------------------------------------ |
| [HTTP](/pages/connectors/sources/http)     | `connectors/http`   | The manifest-driven mechanism the five SaaS sources above run on; new APIs are onboarded declaratively |
| [Sample](/pages/connectors/sources/sample) | `connectors/sample` | Synthetic data, for testing pipelines without a real upstream                                          |

Every source implements the base `Source` contract; several add optional
capabilities like resumability or CDC. See [Optional
interfaces](/pages/connectors/building-a-connector/optional-interfaces) for the
full list.
