Apache Zeppelin

Apache Zeppelin is a web-based notebook for interactive data analytics and collaborative documents. It supports SQL, Scala, Python, R, and other languages through interpreters including Apache Spark, Apache Flink, JDBC, Markdown, and Shell. Users can ingest and explore data, analyze results, and create visualizations, including basic and pivot charts that can display output from any language backend. Its Spark integration can inject Spark contexts automatically, load dependencies at runtime, and show job progress or cancel jobs. The SQL interpreter connects to JDBC sources such as PostgreSQL, MySQL, MariaDB, Redshift, and Apache Hive. Collaborators can share notebook URLs, with changes broadcast in real time. Zeppelin documents single-user and multi-user deployments, including LDAP support. It is self-hosted and open source under the Apache License 2.0. Anonymous access is enabled by default, and the project recommends configuring authentication or limiting use to a secured, trusted environment. Its download options include packages, source code, and Docker; the net-install package includes only the Spark interpreter by default.

Apache Zeppelin combines multi-language notebooks, visualizations, and real-time collaboration in self-hosted open-source software. Pay particular attention to its default anonymous access and configure security for the deployment.

Zeppelin suits people building interactive analytics notebooks with supported languages and data backends. Teams can use its shared notebooks, but deployments need appropriate authentication and security configuration.

Overview

Apache Zeppelin is a web-based notebook for interactive data analysis and collaborative documents. It suits teams that want SQL, Scala, Python, R, and processing backends in one self-hosted workspace. Its breadth is a strength, but deployment and security configuration are part of the job.

Key features

Zeppelin’s pluggable interpreters bring Apache Spark, Flink, Python, R, JDBC, Markdown, and Shell into a shared notebook environment. That makes it practical to move between querying, scripting, and distributed processing in the same document. The flexibility also leaves teams responsible for choosing and installing the interpreters their workflows need: the Spark-focused net-install package includes Spark alone by default, with other interpreters added through its net-install script.

Spark users get automatic SparkContext and SQLContext injection, runtime dependency loading, and controls to cancel jobs and see their progress. These features reduce setup work and make running jobs easier to manage. The SQL interpreter connects to JDBC sources including PostgreSQL, MySQL, MariaDB, Redshift, and Apache Hive.

Charts can visualize output from any language backend, and pivot charts support drag-and-drop aggregation. They help turn notebook results into summaries, though the emphasis is on basic and pivot charts rather than a claim of a full dashboarding suite. Shared notebook URLs and real-time change broadcasts support collaborative analysis; version history adds a way to track notebook changes.

Zeppelin supports single-user and multi-user deployments, including multi-user setups with LDAP. Anonymous access is enabled by default, so an exposed deployment should not be treated as secure without configuration. The project documents Apache Shiro authentication and options including LDAP or Active Directory realms, Knox SSO, Kerberos-based SPNEGO, and secure session cookies. Release 0.12.1 includes fixes for JWT validation, path traversal hardening, and a WebSocket memory leak.

Pricing

Apache Zeppelin is free: the Apache License 2.0 software costs nothing plan and is self-hosted. There is no paid tier to unlock, but hosting and deployment remain the user’s responsibility. Binary packages include an all-interpreters option and a Spark-focused net-install package; source code and an official Docker image are also available. Community participation and issue reports go through the project mailing list and Jira issue tracker.

Platforms

Zeppelin runs on Linux and macOS, is self-hosted, and is accessed through the web. Its deployment model fits organizations that can manage their own environment; it is not a turnkey hosted notebook service.

Who it's for

Choose Zeppelin if your team needs a shared notebook across SQL, Spark, and other language backends, and can take responsibility for deployment and access controls. It is a less natural fit for individuals seeking a managed notebook with no server or security administration.

Pros and cons

• Pros: Multiple interpreters bring SQL, Spark, Flink, Python, R, and other backends into one notebook environment.
• Pros: Real-time collaboration, shared URLs, and version history support teams working on common documents.
• Pros: Free, Apache-licensed software can be deployed on infrastructure the team controls.
• Cons: Anonymous access is the default, making authentication configuration an essential deployment task.
• Cons: The Spark-focused net-install package requires separate installation of any other needed interpreters.
• Cons: Self-hosting puts deployment and ongoing environment management on the user.

Alternatives

JupyterLite is a free, browser-based option when avoiding a dedicated application server matters; kernel and package compatibility depends on the environment. Pluto.jl is another free, open-source notebook to consider if its MIT-licensed offering better fits your choice of software.

Datalore may suit readers who prefer a freemium service: its free Cloud plan includes 120 CPU S machine hours, 10 GB of cloud storage, two notebooks in parallel, and one workspace. Hex offers a freemium alternative, with a free Community plan that includes data-source connections, all cell types, small compute, and an agent trial; its Professional plan is $36 a month, billed per Ed.

marimo is a free, permissively licensed open-source notebook alternative. Nextjournal is worth considering for its free plan with unlimited private notebooks and data and secrets management, alongside limited concurrent and entry-level compute resources. Paperspace Notebooks may fit readers looking for free CPU and GPU notebook machines, with 5 GB of included storage and restrictions on free machines. Saturn Cloud is an alternative with a pay-as-you-go Hosted plan at $0.09 a month, billed hourly, including 16 GB memory, 4 vCPUs, and 0 vGPUs.

Verdict

Apache Zeppelin is a strong choice for teams that want open-source notebooks spanning SQL and multiple processing backends, with real-time collaboration and control over self-hosting. Choose it when that flexibility justifies managing interpreters and securing the deployment; look elsewhere if you need a managed notebook or want safe access without configuring authentication.
