ITFlow

ITFlow is a free, open-source documentation and PSA platform designed for small managed service providers. It consolidates client documentation, asset tracking, contact management, ticketing with SLA timers, invoicing, recurring billing and a client portal into one self-hosted application. ITFlow launched in March 2019 and reached stable release status in January 2025, indicating production-ready maturity for production use.

The platform is positioned as a self-hosted alternative to commercial documentation tools such as IT Glue and Hudu, with no licensing fees or subscription costs. It supports deployment via Docker, Linux apt repositories and HestiaCP integration, giving MSPs flexibility in how they deploy and maintain the system. Because ITFlow is self-hosted, MSPs retain full control of their data and hosting infrastructure, which matters for compliance, data residency requirements and businesses handling sensitive client information. The platform provides a web-based console accessible from any browser, with no desktop client installation required.

ITFlow includes password management with AES encryption, network and asset documentation, vendor tracking, certificate and license management, role-based access controls, an open API for custom integrations, comprehensive audit logging, email-to-ticket functionality, and Stripe integration for online payment collection. It also supports AI integration capabilities with Ollama, LocalAI and ChatGPT for enhanced automation. The project is community-driven with publicly available source code on GitHub, reaching 999 stars and welcoming community contributions. Features span contact management, domain and SSL expiry monitoring, recurring billing automation, and a client self-service portal for quotes, invoices and tickets. MSPs evaluating ITFlow should confirm that self-hosting meets their operational model, verify their team can manage server updates and security patching, and assess whether the open-source community support model meets their expectations, since there is no commercial support contract or guaranteed response time.

ITFlow suits small MSPs comfortable with self-hosting and community-driven support, or those with strict data residency requirements. Unlike IT Glue or Hudu, there is no cloud option and no commercial support tier, so evaluate whether your team can manage server maintenance and patching. The open-source model means you own the code but carry responsibility for upgrades and security. Compare against Hudu and IT Glue on feature depth and total cost of ownership including infrastructure, and confirm the community forum and documentation meet your support needs before migrating.
