Open-Source Tools Built With PHP (2026)
Self-hostable software written in PHP.
If you prefer to run software written in PHP — for easier auditing, contributing, or self-hosting on a stack your team already knows — these 6 open and self-hostable tools are built with it. PHP projects tend to be easy to deploy alongside the rest of your PHP infrastructure.
Open-source self-hostable platform to deploy apps, databases, and services on your own servers.
- Free and self-hostable — one VPS replaces unlimited Heroku dynos
- Web UI covers the full deploy lifecycle without touching the CLI
- Laravel/PHP stack can be heavyweight compared to minimal PaaS alternatives
Open-source, self-hosted file sync, sharing, and collaboration suite.
- Broadest feature set of any self-hosted storage platform — sync, office docs, chat, calendar in one
- Massive community and app ecosystem (a decade of continuous development)
- PHP stack with many moving parts (Redis, cron, optional Collabora container) makes tuning nontrivial at scale
Open-source project management built around goals and lean/agile methodology, not just tasks.
- Unusual goals-first structure connects daily tasks back to strategy explicitly
- Genuinely accessibility-conscious design, documented as a project priority
- Smaller community and plugin ecosystem than Plane, Redmine, or OpenProject
Minimalist, self-hosted kanban board with a single-file PHP install.
- Extremely lightweight — runs comfortably on a $5/mo VPS with SQLite
- MIT licensed, zero paid tier, no telemetry
- Project is in maintenance mode — mostly bug fixes, few new features since 2023
Mature, self-hostable open-source CRM with deeply customizable entities and business-process automation.
- Battle-tested codebase with over a decade of production use
- Highly customizable without needing to modify core code
- PHP/legacy stack is less attractive to modern JavaScript developers
Free, open-source client file-sharing portal built for sending files to customers, not team sync.
- Completely free with no paid tier, ever, under GPL-2.0
- Purpose-built for client-facing file exchange rather than internal team sync
- Not a sync tool — there's no desktop client or continuous folder sync, just web upload/download
