Free browser helpers for n8n, API, and webhook problems

These three tools stay in your browser. Use them when a workflow looks fine but the payload, the schedule, or a retried webhook is the real problem. Nothing is uploaded or stored. If the tool is not enough, send the problem and we will write a short review, free.

Each tool does one job. Compare two JSON payloads when an API shape drifts. See the next times an n8n cron will fire. Build a retry key so the same webhook does not run twice.

JSON diff

Paste a before and after payload. See added, removed, and changed paths when an API or webhook schema drifts.

n8n cron next runs

Paste a 5-field or 6-field cron, pick a timezone, and read the next 10 fire times.

Webhook idempotency

Build a SHA-256 retry key for Stripe, Shopify, GitHub, or a custom JSON body.
