dtex
dtex ("data extraction tool") is an open-source, self-hosted Python extract-load (EL) tool. It moves data from a source (an API, a database, a file drop) into a destination (a warehouse, a database, an object store) — and nothing more. Transformation is dbt's job.
The pitch in one line: a CLI-first, dbt-shaped extract-load tool — pipelines are configs, connectors are folders, no UI blackbox. The #1 principle is to keep it as simple as possible.
Install
pip install dtex # every baked connector, ready
pip install 'dtex[gcs,s3]' # add gs:// / s3:// filesystem reads
pip install 'dtex[gcp-secrets]' # add the GCP Secret Manager resolver
pip install 'dtex[aws-secrets]' # add the AWS Secrets Manager resolver
pip install 'dtex[vault]' # add the HashiCorp Vault resolver
pip install dtex ships every baked source and destination — DuckDB,
BigQuery, the filesystem source's local + Parquet path, the REST / Postgres
/ ShipHero / Stripe sources, the engine, the CLI. Extras stay opt-in for the
cloud-storage paths of the filesystem source (gs:// / s3://) and for
secret managers (only relevant if your profiles.yml uses secret:// URLs).
dtex requires Python 3.11+. It installs both a CLI (dtex) and an importable
library (import dtex).
Usage
dtex init my_project # scaffold a project
cd my_project
dtex new source my_api # scaffold a source connector
dtex new config my_pipeline # scaffold a pipeline config
dtex validate # check everything
dtex run -p my_pipeline # run the pipeline
dtex runs list -p my_pipeline # show recent run history
A pipeline is one config file binding a source + a destination + a target +
params. Run it with dtex run -p <config>. The library equivalent is
dtex.run(config="my_pipeline") and returns a structured RunResult.
Pre-baked connectors
Each connector ships with its own README — click through for the auth checklist, scope requirements, schema, and known limitations.
Sources:
| Connector | What it does |
|---|---|
filesystem |
CSV / JSONL / Parquet from local, GCS, or S3 |
rest |
Paginated REST APIs — 4 pagination strategies, 4 auth modes |
postgres |
Keyset pagination, no OFFSET |
shiphero |
GraphQL |
stripe |
REST resource-as-stream + opt-in Sigma SQL-as-stream |
revenuecat |
v2 API — customers + subscriptions + daily chart metrics |
chargebacks911 |
CBAPIv2 — prevention alerts + chargeback cases, incremental |
gads |
Google Ads — GAQL query-as-stream + MCC account auto-discovery |
singular |
Singular.net Reporting API — daily network + agency-tagged attribution reports |
intercom |
Intercom REST API — contacts, conversations + transcript parts, tickets, companies, articles, workspace dimensions; Airbyte-compatible column shapes |
meta |
Meta (Facebook / Instagram) Ads — ad-level daily + campaign-level hourly insights via async report jobs. Created by Auste Luksaite |
Destinations:
| Connector | What it does |
|---|---|
duckdb |
Zero-config dev default, all 5 capabilities |
bigquery |
Production warehouse — Parquet-staged via GCS + LOAD jobs, MERGE upserts, cursor-based partitioning |
Engine: per-stream commit + atomic transactions (rollback on failure),
state in the destination's _dtex_state table, run records in _dtex_runs,
structured JSON-lines logs per run, secret redaction, schema evolution
(evolve default, strict opt-in), pipeline-level parallelism with
per-destination caps.
Secret managers: GCP Secret Manager, AWS Secrets Manager, HashiCorp Vault — each as an opt-in extra.
Bundled Claude skills
dtex ships three Claude skills inside the wheel:
dtex-write-config, dtex-write-connector, dtex-debug. They teach
Claude (or any other agent runtime that reads .claude/skills/) the
post-streams-redesign config schema, the @stream decorator pattern, and
the debugging playbook. Install them into a dtex project with:
dtex skills install # copies into ./.claude/skills/dtex/
The first dtex command run inside a project that lacks installed skills
prints a one-line hint (suppressed thereafter). Run dtex skills list to
see which ship with this dtex version and which are installed locally.
If you're not using Claude, just ignore the hint — the skills are inert markdown until installed.
