Flowsanity

Flowsanity is a 24/7 support service for n8n workflows that connects to Cloud or self-hosted instances without requiring migration or workflow changes. It monitors executions to detect failures, including those that complete successfully but drop records silently, and diagnoses issues like expired credentials or non-firing webhooks. When a problem is found, the service explains the issue in plain English and proposes a fix that the user approves before it is applied.

The service operates on a monthly subscription basis with a one-time setup fee of €990, which is waived for the five founding spots. Founding spots also lock the price for 12 months from launch, while standard plans range from €249 to €749 per month depending on the number of workflows and features included.

To get started, users reserve a pilot spot by providing a work email, company and role, and optionally selecting a preferred plan. This process takes about two minutes, is non-binding, and requires no payment details upfront before a concrete pilot offer is generated within 24 hours.

The process begins by pointing the service at the n8n Cloud or self-hosted instance, which takes about 15 minutes. Next, Flowsanity watches every execution 24/7 to catch hard crashes, flaky webhooks, expiring credentials, and silent data drops. Finally, it resolves issues by sending a plain-English message via Slack or email, waiting for user approval before automatically fixing the failure next time.

The service is designed for businesses running n8n automations that need to catch silent failures that standard dashboards miss. It is particularly useful for teams dealing with expired OAuth tokens, webhooks returning 404s in production, or APIs that change response formats without alerting the user.

Some reviewers note that the service catches failures that appear successful on the dashboard, such as 36 out of 49 records silently dropping while the status remained green. This ability to identify silent data drops and explain them in plain English is frequently praised as a key feature.

A common theme among complaints involves the initial setup or connection process, where users may struggle to point the service at their n8n instance without making changes to existing workflows. Additionally, some users express concern about the reliance on external communication channels like Slack or email for receiving diagnostic messages.

The service offers a white-label monthly report and per-client approval rules for agencies managing multiple client instances. Agencies can access a single board for all client instances starting from €199 per agency, with custom scopes available for more than 15 workflows.

The private pilot program is scheduled to launch in September 2026 with a limited number of five founding spots. Reserving a spot is non-binding and commits the user to nothing, allowing them to decide on a concrete pilot offer within 24 hours.

Flowsanity is a product of Wimmer Ventures UG (haftungsbeschränkt), which is based in Munich. The business operates globally, serving clients who use n8n Cloud or self-hosted instances regardless of their geographic location.

The service provides multi-channel alerts as part of its Scale plan, allowing users to receive notifications through various channels beyond just Slack or email. This feature helps ensure that critical workflow failures are noticed promptly across different communication preferences.

One-time setup and onboarding costs €990, but this fee is waived for the five founding spots. The service also offers a non-binding reservation process that does not require any contract or payment obligation before the pilot offer is provided.

The service operates on a 24/7 basis, ensuring that support is always available to detect and resolve workflow failures. This continuous monitoring is a core part of the service, covering hard crashes, flaky webhooks, and silent data drops without interruption.
