Seal Report
Open-source reporting and BI for .NET — MIT-licensed, with built-in AI agents.
Seal Report turns any SQL or NoSQL source into reports, pivot tables, charts and scheduled outputs, and runs ETL and batch tasks. Self-hosted on Windows or Linux, written in C# and developed since 2015. A self-hosted alternative to SSRS or Power BI Report Server.

Ask an agent in plain language: it inspects your data sources, answers with the data, then builds and saves the report.
What's new in version 10
- MIT License: free for everyone, including commercial and embedded use.
- AI Agents: design reports, analyze data, manage data sources and schedules by chat, with your own provider (OpenAI, Azure OpenAI, Anthropic, or local models through Ollama).
- .NET 10 on Windows and Linux.
- New web interface on Bootstrap 5, with ECharts added to the chart engines.
- SharePoint as an output destination for scheduled reports.
See the release notes for details.
Main Features
- Dynamic SQL sources: Use your own SQL, or let the Seal engine build the SQL used to query your database dynamically.
- LINQ queries: Join and query any data sources (SQL, Excel, XML, OLAP Cube, HTTP JSON, etc.) with the power of LINQ.
- Native Pivot Tables: Drag and drop elements directly in a pivot table (cross tab) and display them in your report.
- HTML5 Charts: Define and display chart series in two mouse clicks (support of ChartJS, ECharts, Plotly, ScottPlot and Gauge libraries).
- Maps: Display the rows of a model having a latitude and a longitude on an interactive map, with colors, sizes and popups (OpenStreetMap, OpenTopoMap, OpenHikingMap, IGN or your own tiles).
- AI Agents: Chat with role-based AI agents to design reports, analyze data, manage data sources, schedule executions or administer the server — using your own provider (OpenAI, Azure OpenAI, Anthropic or Ollama, including local models). AI tasks can also be embedded in reports.
- Fully responsive HTML rendering with the Razor engine: Use the power of HTML5 in the report result (Bootstrap layout, responsiveness, table sorting and filtering). Customize your report presentation in HTML with Razor parsing.
- Excel and PDF: Full control of your report result in Excel (ClosedXML library) or PDF (QuestPDF library). Several other formats are available (XML, JSON, Text, CSV) or can easily be customized.
- KPI and Widget Views: Create and display your Key Performance Indicators in a single report.
- Web Report Server: Publish your reports on the web (Windows and Linux with .NET).
- Report Scheduler: Schedule report executions and generate results in folders, FTP/SFTP servers or SharePoint document libraries, or send them by email (SMTP, SendGrid or MS Graph) — integrated with the Windows Task Scheduler or available as a service.
- Drill down navigation and sub-reports: Navigate in your report result to drill to a detail or to execute another report.
- Report Tasks & ETL: Define tasks to perform your ETL or batch operations (data load, Excel load, file download from FTP or SFTP, zip, backup, data processing, etc.) or to trigger procedures from external assemblies.
- Native support of MongoDB.
- NuGet packages to ease integration into existing projects.
- Low TCO (total cost of ownership): Designed for minimal ongoing maintenance.
Quick Start
- Install: Download the latest setup from GitHub Releases.
