Its own framing is a workspace where research scientists can **Pricing & Plans:** Contact for pricing. llog does not publish a public price list; as a research-focused platform it is scoped and quoted directly with the vendor. - **Templatized configs:** llog turns YAML configs and argparse code into guided, visual templates so experiments are reproducible by default. - **Visual web GUI:** Modify experiment parameters visually in a web GUI instead of editing files by hand, and add a new parameter across an entire pipeline in one click. - **No-code visualisation:** Visualise experiment outputs without writing code, and ask the AI questions to plot features in your data. - **Server and SLURM launching:** Launch and run experiments on your own server or through SLURM, with version control so runs can be reproduced. - **AI data merging and predictive analytics:** llog's AI finds keys, joins tables efficiently and supports predictive analytics and load testing to forecast pipeline failures. **Strengths:** Targets the real pain of reproducible ML experiments; Visual GUI reduces hand-editing of YAML and code; Launches on your own infrastructure or SLURM; AI-assisted data merging with auditable join rules **Limitations:** The live site was returning a Cloudflare 525 origin SSL error during review, so availability may be intermittent; Aimed at ML research teams, so it requires committed engineering and infrastructure to justify; Useful mainly if you run experiments on your own servers or SLURM clusters; Exact pricing is not published openly — custom plans require contacting the team [Profile (Markdown)](https://openaitools.app/tool/llog.md) ## Rerun Rerun is an open-source SDK and visualizer built for multi-rate, multimodal data, and it markets itself as the data layer for physical AI. Engineers use it to log sensor streams, computer-vision outputs, 3D transforms, and time-series metrics from the first recording through to large-scale review. Because it is a flexible framework rather than a locked platform, teams can extend the viewer with their own views and tools at each stage of the pipeline. The SDK ships with Python, Rust, and C++ APIs, so it fits into existing robotics and perception stacks without a rewrite. Data is stored as column-chunks in rrd files, which supports full dataframe or SQL queries over any recording, down into the columns, time ranges, and values inside it rather than only metadata. Beyond the free tooling, Rerun offers Rerun Hub, a production backend that catalogs recordings, indexes byte ranges, and turns object stores into a queryable, streamable foundation. Hub supports running transforms on the edge or close to the data and streaming datasets directly to GPUs for training without an export step. **Pricing & Plans:** The Rerun SDK and viewer are open source and free to use. Rerun also offers Rerun Hub, a production backend, whose pricing is arranged separately with the team. Check the Rerun website and GitHub repository for current terms. - **Multimodal data visualization:** Log, store, and view images, point clouds, 3D transforms, and time series together in one viewer. - **Open-source logging SDK:** Record multi-rate, multimodal data as column-chunks in rrd files, or convert from other formats. - **Query and transform:** Run full dataframe or SQL queries over robotics data, down into columns, time ranges, and values. - **Edge and stream transforms:** Add derived columns and evolve schemas without breaking history, on the edge or near the data. - **Rerun Hub backend:** A hosted backend with catalog, byte-range indexing, and retrieval that turns object stores into a queryable dataset. **Strengths:** Open-source core with permissive use across research and production; Handles multimodal and multi-rate data in one viewer; APIs for Python, Rust, and C++; Query and transform data without an export step **Limitations:** Requires coding in Rust, Python, or C++ to get full value; The hosted Rerun Hub backend is a newer, additional product beyond the free SDK; Visualization work is aimed at engineering teams, not general business users; Advanced production features assume existing logging pipelines [Profile (Markdown)](https://openaitools.app/tool/rerun.md) ## Frequently Asked Questions ### How do llog and Rerun compare in monthly traffic? llog has 0 monthly visits, while Rerun has 54,018.
