## 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

## Whimsical

Whimsical is a collaborative visual workspace aimed at product builders — designers, product managers, engineers and the cross-functional teams around them. Instead of juggling a diagramming app, a whiteboard, a wireframing tool and a docs tool, Whimsical puts diagrams, flowcharts, mind maps, wireframes, boards and clutter-free documents on a single infinite canvas. Everything is real-time multiplayer, so a sprint-planning flowchart or a user-flow wireframe can be sketched, commented on and refined by the whole team in one shared space.

Its AI layer is what makes Whimsical more than a drawing tool. AI Flowcharts turns a written process description into a structured flowchart with a single prompt; AI Mind Maps expand one idea into a fully branched tree you can reorganise; AI Wireframes generate editable wireframes and wireflows for web and mobile from text. Because the output is native, editable Whimsical content rather than a static image, the AI acts as a first-draft accelerator instead of a dead end.

Around the canvas sits the practical scaffolding that teams need: reusable templates, comments attached to the exact object in question, image and video embeds (Loom, YouTube and more), version history with restore, live embeds inside other tools, Slack and GitHub integrations, and a desktop app for macOS and Windows. Admins on larger plans get private teams, SAML SSO, SCIM provisioning and content security locks, which is why Whimsical scales from a solo PM to an entire organisation. Whimsical, Inc. states it is SOC 2 Type 2 compliant and supports GDPR and CCPA requirements.

**Pricing & Plans:** Freemium. The Free plan costs $0 and includes unlimited boards and members but limits output to 50 board objects and 50 doc blocks per month with export watermarks and 7-day history. Pro is $10 per editor/month billed annually ($12 monthly) with unlimited objects, no watermarks and 90-day history. Business is $20 per editor/month annually ($24 monthly) and adds private teams, SAML SSO, SCIM, security controls and unlimited version history. Viewers and guests are always free; students, teachers and non-profits get special pricing.

- **Prompt-to-visual AI tools:** AI Flowcharts, AI Mind Maps and AI Wireframes convert a short text prompt into structured, fully editable diagrams, branched mind maps, or web and mobile wireflows — no manual drawing required.
- **One infinite canvas:** Boards host diagrams, flowcharts, mind maps, wireframes, embedded media and documents side by side, so a whole product narrative lives in a single shareable file.
- **Real-time multiplayer editing:** Multiple teammates edit the same board simultaneously with live cursors, thread comments attached to specific objects, and mention-based notifications.
- **Wireframing and user flows:** Drag-and-drop UI components let teams sketch screens, link them into clickable flows and iterate on product ideas before engineering commits to a build.
- **Enterprise-ready controls:** Private teams, SAML single sign-on, SCIM provisioning, role management, user offboarding file transfers and content security locks support large organisations.

**Strengths:** AI generates native, editable Whimsical objects rather than flat images; Single workspace replaces separate diagramming, whiteboarding, wireframing and docs tools; Unlimited viewers and guests are free on every plan, including Free; Fast, lightweight editor with an excellent template library

**Limitations:** Free plan caps you at 50 board objects and 50 doc blocks per month plus export watermarks; AI credits are limited per seat and extra credits cost more; Advanced admin and security features are locked behind the Business tier; Very large, asset-heavy boards can feel slower than focused single-purpose tools
