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.

Collaborative inbox and email management for teams
Let multiple people work the same inbox with clear assignment, internal statuses, and visibility into who is answering what.
Discuss and prepare replies inside the email thread itself, so context stays attached and nobody is left out of the loop.
Turn any email into an assigned task and see what each teammate is working on today, tomorrow, and next week.
Automate repetitive routing, tagging, and follow-up with rules, rule templates, and workflow automations.

Provides clean inbox prioritization and smart summaries, but lacks deep team chat integration and shared inbox workflow rules.
