Doxygen vs Mihari

Doxygen is a free documentation generator that turns source-code comments into reference material, parsing items such as classes, functions and variables. It supports C/C++, Lex, Java, Python, VHDL, PHP IDL, C#, Fortran, Objective-C 2.0 and some D sources. Output can be generated as HTML, PDF through LaTeX, Word through RTF or structured XML for external tools. Graphviz’s dot tool can add include-dependency, collaboration, call, directory-structure and class-hierarchy diagrams. Doxywizard provides a graphical interface for editing settings and running the generator on Windows, Linux and macOS; Doxygen also works on many Unix flavors. It supports HTML Help, docsets, Qt-Help and Eclipse Help, with more than 100 configurable options. The tool runs without registration and does not collect personal or usage data. It is self-hosted and licensed under the GNU General Public License, without express or implied warranty. Help is listed through Stack Overflow and the doxygen users mailing list; commercial feature and bug-fix support has limited capacity.

Mihari is a cloud observability platform combining uptime monitoring, on-call alerting, telemetry, API documentation, and error tracking. Its European probes check HTTP, TCP, DNS, and ICMP at intervals down to 30 seconds. On-call tools provide rotation schedules, escalation chains, and notifications through email, SMS, phone calls, Slack, Microsoft Teams, PagerDuty, and webhooks. Telemetry covers logs, metrics, and distributed tracing, with OpenTelemetry and Prometheus ingestion. Error tracking records stack traces, source maps, and contextual breadcrumbs, and groups duplicate errors. The free plan includes 10 monitors, one status page, 1 GB of logs retained for seven days, three dashboards, one documentation project, five team members, one escalation policy, email alerts, and 5K error events monthly. Platform access costs €19 per month; Early Access costs €19 one-time. Mihari is web-based, hosted in France, GDPR compliant by design, and in public beta.
