Research Question
The user sought self-hosted (on-prem or private cloud) workflow automation platforms suitable for lead follow-up tasks, such as processing form submissions, lead scoring, CRM routing, and sales notifications.
Key Findings
- Platforms supporting self-hosting include n8n, FlowFuse, and Windmill; all are open-source with free tiers fitting 3 workflows, 5 steps each, and 500–5,000 executions/month.
- n8n offers intermediate difficulty, 1-hour setup, $0 monthly/annual cost (Community tier), best for self-hosted teams, but requires DevOps capacity.
- Windmill has advanced difficulty, 2.5-hour setup, $0 cost (Free and Open-source tier), suited for script-heavy automation, unsuitable for non-developers.
- FlowFuse features advanced difficulty, 3-hour setup, $425 monthly/$4,675 annual cost (Pro Self-hosted tier), optimized for IoT-integrated workflows, requires server admin skills.
- Automating lead follow-up saves $12,000 annually versus manual processes.
Recommendation
n8n is recommended as the primary platform due to its free self-hosted Community edition, quickest 1-hour setup, and intermediate accessibility for lead routing and scoring tasks. Use Windmill as an alternative for script-intensive needs. Assumes availability of basic DevOps skills; verify current fit against team expertise.
Details
Self-hosted costs remain $0 for n8n and Windmill across 500–5,000 executions/month, as they lack per-execution billing in open-source editions.
