The idea is simple: <strong>Make data integration and synchronization easier for everyone.</strong></p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Frw70uanhz93azqp424wa.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Frw70uanhz93azqp424wa.png" alt=" " width="800" height="394"></a></p> <div class="crayons-card c-embed"> <br> Apache SeaTunnel is a powerful engine, but the learning curve—writing configs, managing jobs manually, checking logs—can be high for new users or data analysts.<br> </div> <h2> What is SeaTunnel Web? </h2> <p><strong>SeaTunnel Web</strong> is a visual console designed to help users create, run, and monitor SeaTunnel jobs without diving into complex configuration files.</p> <p>Instead of starting from scratch, you can manage pipelines through an intuitive interface focusing on:</p> <ul> <li> <strong>Visual job creation</strong> (Batch &amp; Streaming)</li> <li> <strong>Data source management</strong> &amp; connection testing</li> <li> <strong>Observability</strong>: Runtime logs, metrics, and instance tracking</li> </ul> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fe8gyh2y89sqvo4me68xd.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fe8gyh2y89sqvo4me68xd.png" alt=" " width="800" height="394"></a></p> <h2> Why build it? </h2> <p>In the real world, "I just want to sync MySQL to PostgreSQL" sounds simple, but the details are painful: field mapping, job mode selection, and status monitoring.</p> <p>I built this to organize these details into a guided workflow. It doesn’t hide the power of SeaTunnel; it just makes the first step much smoother.</p> <h2> Key Features </h2> <h3> 1. Source Management </h3> <p>Test your connections (MySQL, Oracle, etc.) before running the job to reduce early-stage errors.</p> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fbb965t5bd4xe2p3tkhhf.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fbb965t5bd4xe2p3tkhhf.png" alt=" " width="800" height="394"></a></p> <h3> 2. Guided Synchronization </h3> <p>Support for:</p> <ul> <li>Multi-table synchronization</li> <li>Custom field mapping</li> <li>Automated config generation</li> </ul> <p><a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F4v9h7bsg6w7b104ep8sg.png" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F4v9h7bsg6w7b104ep8sg.png" alt=" " width="800" height="394"></a></p> <h3> 3. Full Observability </h3> <p>Answer "Is it running?" or "Why did it fail?" instantly through the dashboard.</p> <h2> Keep the Power, Simplify the Operation </h2> <p>My philosophy is: <strong>Simplify common operations, but keep advanced capabilities available.</strong> For experts, we still support script modes and custom parameters. </p> <h2> Check it out </h2> <p>SeaTunnel Web is evolving, and I’d love your feedback.</p> <div class="ltag-github-readme-tag"> <div class="readme-overview"> <h2> <img src="https://assets.dev.to/assets/github-logo-5a155e1f9a670af7944dd5e12375bc76ed542ea80224905ecaf878b9157cdefc.svg" alt="GitHub logo"> <a href="https://github.com/weifuwan" rel="noopener noreferrer"> weifuwan </a> / <a href="https://github.com/weifuwan/seatunnel-web" rel="noopener noreferrer"> seatunnel-web </a> </h2> <h3> SeaTunnel Web is a visual platform for building, managing, and monitoring Apache SeaTunnel data pipelines with DAG orchestration and connector configuration. </h3> </div> <div class="ltag-github-body"> <div id="readme" class="md"> <p> <a rel="noopener noreferrer" href="https://private-user-images.githubusercontent.com/78582861/572938335-901d765c-cbd7-4f39-ae3a-de6716ae09f2.png?jwt=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.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.CfwT77ng-Iz_njPT8SfsbiTeZtyBTIgJZPJLoR1rFzs"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fprivate-user-images.githubusercontent.com%2F78582861%2F572938335-901d765c-cbd7-4f39-ae3a-de6716ae09f2.png%3Fjwt%3DeyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.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.CfwT77ng-Iz_njPT8SfsbiTeZtyBTIgJZPJLoR1rFzs" width="100%" alt="Nest Logo"></a> </p> <p> <a href="http://111.230.213.87:8000" rel="nofollow noopener noreferrer">Live Demo</a>｜ <a href="https://doc.seatunnel-web.com/" rel="nofollow noopener noreferrer">中文文档</a>｜ <a href="http://111.230.213.87:9001/" rel="nofollow noopener noreferrer">官网</a> </p> <div class="markdown-heading"> <h2 class="heading-element">SeaTunnel Web</h2> </div> <p><strong>SeaTunnel Web</strong> is a modern web-based management platform for <strong>Apache SeaTunnel</strong>, designed to simplify the creation, configuration, and operation of data integration pipelines.</p> <p>It provides a visual interface to build data pipelines using <strong>DAG orchestration</strong>, manage connectors, configure jobs, and monitor task execution.
