Instant Postgres branches so coding agents can test safely
Create a 1:1 copy of any Postgres database in under six seconds and keep that speed even at terabyte scale, so agents never wait on test environments.
Every branch is isolated at the compute and storage level, meaning experiments, migrations, and data cleaning can never reach or damage production.
Clones only consume storage for the changes actually made, instead of duplicating the full dataset for every branch.
Branch compute scales with agent workloads and drops to zero when idle, so you never pay to keep idle test databases running.

Turn plain text into diagrams, infographics, and presentation-ready visuals.
Paste or import your text and Napkin generates infographics, diagrams, flowcharts, mind maps, and data charts that fit your content.
Napkin Slides collaborates with you to turn ideas into complete, ready-to-present decks rather than static images.
Adjust colors, fonts, layouts, and icons, reshape individual elements, and match your brand — nothing is locked after generation.
Export visuals as PPT, PNG, PDF, or SVG and drop them into PowerPoint, Google Slides, Keynote, Notion, or any tool you already use.
