What is Maddy?
A one-binary mail server learning to behave like production infrastructure.
maddy is an all-in-one SMTP and IMAP server written in Go, aimed at people who want a working mail host without assembling Postfix, Dovecot and a policy daemon themselves. The 0.9 line moved quickly — 0.9.0 through 0.9.5 between late March and late May — with the sequence following a recognisable shape: a feature release, an immediate patch for a broken integration, a security release, then cleanup. Configuration is directive-based, and much of the changelog concerns the behaviour of individual modules like auth.ldap, check.rspamd and check.dnsbl.
What is Krisp?
Krisp adds deepfake detection and expands Voice Translation as its Call Center AI platform deepens enterprise compliance tools.
Krisp has shifted from a personal noise-cancellation app to a B2B Call Center AI platform, shipping weekly web updates and biweekly desktop releases. The current product spans real-time Voice Translation across 12+ languages including Cantonese and Valencian, Accent Conversion with per-regional models, and admin-layer tools including Conditional Call Recording, Live Call Audit enforcement, and a new Notification Center. A lower-cost evaluation tier appeared in August, suggesting friction at the top of the sales funnel.
Maddy vs Krisp: editorial side-by-side
Maddy
0.0COMMS
A one-binary mail server learning to behave like production infrastructure.
◆ Current state
maddy is an all-in-one SMTP and IMAP server written in Go, aimed at people who want a working mail host without assembling Postfix, Dovecot and a policy daemon themselves. The 0.9 line moved quickly — 0.9.0 through 0.9.5 between late March and late May — with the sequence following a recognisable shape: a feature release, an immediate patch for a broken integration, a security release, then cleanup. Configuration is directive-based, and much of the changelog concerns the behaviour of individual modules like auth.ldap, check.rspamd and check.dnsbl.
◆ Where it's heading
The project is systematically removing the compromises that made early versions convenient. Obsolete SASL LOGIN was disabled by default, the STARTTLS plaintext fallback was dropped, the maddyctl symlink behaviour and the implicit run command were deleted after four years of deprecation warnings, and libdns providers that have not kept up with 1.x are being cut. Running the other way is operational maturity: no-downtime config reload, queue-length metrics, OpenMetrics fixes, systemd readiness reporting, and SLSA build attestations on release artifacts. This is a project moving from hobbyist-friendly to operator-friendly, and accepting breakage to get there.
◆ Prediction
0.10.0 is already scoped by the deprecations announced in 0.9.1 — expect the flagged libdns providers to be removed and gandi to require Bearer tokens. Given the 0.9.x pattern, a feature release followed quickly by an integration fix is the likely shape.
Krisp
5.0COMMS
Krisp adds deepfake detection and expands Voice Translation as its Call Center AI platform deepens enterprise compliance tools.
◆ Current state
Krisp has shifted from a personal noise-cancellation app to a B2B Call Center AI platform, shipping weekly web updates and biweekly desktop releases. The current product spans real-time Voice Translation across 12+ languages including Cantonese and Valencian, Accent Conversion with per-regional models, and admin-layer tools including Conditional Call Recording, Live Call Audit enforcement, and a new Notification Center. A lower-cost evaluation tier appeared in August, suggesting friction at the top of the sales funnel.
◆ Where it's heading
The update cadence and content point at enterprise expansion: each weekly batch adds granular admin controls, API access for audit data, and new BPO visibility tools. Voice Translation language coverage is widening consistently. Deepfake risk visibility—added in the most recent batch—signals Krisp moving into a trust-and-compliance layer for AI-assisted calls, not just audio quality.
◆ Prediction
The deepfake detection work is nascent; expect it to grow into a standalone compliance dashboard. Enterprise RFPs increasingly require call-authenticity guarantees, and Krisp's audio-layer position gives it a defensible angle on that problem that CRM or WFM vendors can't replicate.
