Apache Zeppelin vs Google Colab

Apache Zeppelin is a web-based notebook for interactive data analytics and collaborative documents. Its pluggable interpreters support work in SQL, Scala, Python, R, and other languages, with backends including Apache Spark and Flink. Use it to ingest and explore data, analyze results, and create visualizations. Built-in charts can display output from any language backend; pivot charts support drag-and-drop aggregation. The Spark integration can provide SparkContext and SQLContext automatically, load dependencies at runtime, and show job progress or cancel jobs. Its SQL interpreter connects to JDBC sources such as PostgreSQL, MySQL, MariaDB, Redshift, and Apache Hive. Collaborators can share notebook URLs and receive changes in real time. The project documents single-user and multi-user deployments, including LDAP support. Zeppelin is open source under the Apache License 2.0 and costs nothing. It runs on Linux, macOS, self-hosted, and web environments. Anonymous access is enabled by default, so its documentation recommends configuring authentication or limiting use to a secured, trusted environment.

Google Colab lets users write and run Python in a browser without configuring a local environment, with access to GPUs and notebook sharing. Its hosted Jupyter notebooks combine executable code with rich text, images, HTML, and LaTeX. Data can come from Google Drive, spreadsheets, GitHub, and other sources, with Google Cloud Storage, Sheets, and BigQuery resources listed for integration. Colab AI can generate or transform code, explain Python libraries, suggest fixes, and perform multi-step data-analysis workflows. By default, it does not access Drive files or user secrets, though it can generate code to access them when explicitly requested. Google says generative-AI features collect prompts, related code, outputs, usage information, and feedback; human reviewers may process that data for up to 18 months. Free notebooks can run for at most 12 hours, depending on availability and usage. Pro+ supports continuous execution up to 24 hours when enough compute units are available. Colab also has a Visual Studio Code extension and a beta, allowlist-gated API. Paid plans start at 8.33 USD/user/mo (annual).
