Local-first Nextflow debugging  ·  Open beta soon

Understand why your
Nextflow pipeline failed.

GenoLoom turns Nextflow DAGs, traces, logs, reports, and timelines into one visual debugging surface. Move from failure to root cause without digging through work directories.

✓  You're on the list. We'll be in touch.

Early access for bioinformatics teams running Nextflow locally or on shared infrastructure.

Explore

From failed run
to root cause.

GenoLoom keeps the familiar Nextflow artefacts, but gives them a visual interface built for debugging, review, and team handover.

01

Load or run a workflow

Upload a Nextflow dag.dot and trace.txt, or launch approved nf-core workflows locally from the workbench.

02

Read the workflow clearly

Switch between a clean process view and the full task-level DAG. See status, counts, and dependencies at a glance.

03

Follow the failure

Highlight failed paths, identify likely root cause nodes, and separate the first failure from downstream noise.

Debugging tools
for real pipelines.

Process and DAG Views

Collapse noisy task graphs into readable process nodes, then jump into the full DAG when you need task-level detail.

Failure Path Highlighting

Trace failed execution through the workflow and identify likely root cause steps before chasing downstream symptoms.

Task Drill-down

Open any process to inspect its underlying tasks, status counts, duration, hashes, and execution metadata.

Inline Artefact Viewer

Inspect .command.sh, stdout, stderr, Nextflow reports, and timelines directly inside the app.

Local-first Execution

Run approved nf-core workflows locally and keep sensitive data inside your own environment.

Built for Teams

Make complex pipeline runs easier to explain, hand over, review, and debug across bioinformatics teams.

Start with nf-core.
Grow from there.

wf::future

Workflow catalogue

Approved local workflows, parameter forms, and richer nf-core integration as the workbench grows.

For teams who
live in Nextflow.

Bioinformatics Teams

Debug production and research workflows faster. Keep the graph, task metadata, logs, reports, and timelines in one place.

Genomics Core Facilities

Give scientists and support staff a clearer way to understand failed runs without handing everyone a terminal and a work directory.

Clinical and Secure Environments

Run locally where data governance matters. GenoLoom is designed around local-first execution and controlled workflow entry points.

Try GenoLoom
on your own runs.

Join the early access list for the local version, demo data, and setup notes. Designed for teams who want to debug Nextflow without sending data elsewhere.
