Everything we've built, in one place.

Yukthi Webmail

A next-generation successor to RoundCube, free and open source, and built to compete with Gmail.

A modern React frontend on a Python backend, built to move mail hosts and self-hosters past RoundCube. It's also what our own Yukthi Mail cloud service runs on, at roughly 80% feature and UX parity with Gmail, free to run yourself.

Yukthi Mail Archival

Multi-tenanted email archival, built to scale to exabytes.

A Google Vault-style archival system, multi-tenanted from the ground up for MSPs and companies managing mail for many customers at once, built to scale to exabytes. The admin UI, the IMAP sync engine, and the export tooling underneath are components of the same system.

• → Archival admin UI: archiving, legal-hold and retrieval
• → IMAP Sync Tool (Go): syncs mail into the archive over IMAP, ~6TB in 40 hours
• → Archive Downloader (Go): exports archived mail as optimized ZIPs, ~1.2M emails in ~40 minutes

Yukthi Content Filter

A spam and content filter written fresh in Go, built for Postfix.

Written from scratch in Golang rather than patched onto decades-old code, fast and customizable with your own rules. Works directly with the Postfix MTA, so it drops into a mail stack you probably already run.

Phoenix Admin

A large-scale admin console with 25+ sections for running the mail hosting operation, currently migrating to Phoenix V3.

The operational console behind the platform, with 25+ sections covering user management, domains, mail flow, security policy, and day-to-day hosting administration. This is the tool our own team uses to run the business. Phoenix V3, a major infrastructure upgrade, is already serving production traffic while the migration finishes in stages.

Phoenix SSO

Company-wide single sign-on across the Yukthi stack.

One identity across Webmail, Archival, and everything else we build. Phoenix SSO already handles sign-on across the stack today, and every new product is built to use it rather than roll its own auth. It ships with an admin UI and an API alongside the sign-on flow itself.

Mail25

TOTP authenticator app for login and account security.

An in-house TOTP authenticator app that generates login codes and manages authenticated sessions across the stack, the same job apps like Google Authenticator do, built and maintained by us.

Yukthi Chat

A Slack-inspired collaboration platform with file sharing, plus a companion mobile app.

Our current focus beyond mail. Channels, DMs, threads, file sharing, and a mobile app to go with it, built to plug into Phoenix SSO from day one, the way every product after it will.
