What is Respond.io?
Respond.io is tuning its AI agents for how messaging actually behaves, not how APIs do.
The recent run splits between AI agent behaviour and channel plumbing. AI Agents gained a configurable wait time so they respond to a complete thought rather than each fragment of a multi-message burst, the ability to send real file and image attachments instead of links, and awareness of assignment and reopen events. On the channel side: WhatsApp carousel templates, Instagram Story mentions as conversation triggers, a Calendly integration, and a Cmd+K command palette that searches any contact field without building a segment.
What is Ergo?
Ergo keeps tracking IRCv3 upstream while quietly opening its history layer to real databases.
Ergo ships roughly two releases a year, each announced as a release candidate about a week ahead of the final. The content is consistent: whatever IRCv3 specifications have firmed up since the last cycle, plus bug fixes and config-format adjustments. The one structural change in this window was pluggable history storage, which took Ergo off its embedded database as the only option.

Respond.io is tuning its AI agents for how messaging actually behaves, not how APIs do.
◆ Current state
The recent run splits between AI agent behaviour and channel plumbing. AI Agents gained a configurable wait time so they respond to a complete thought rather than each fragment of a multi-message burst, the ability to send real file and image attachments instead of links, and awareness of assignment and reopen events. On the channel side: WhatsApp carousel templates, Instagram Story mentions as conversation triggers, a Calendly integration, and a Cmd+K command palette that searches any contact field without building a segment.
◆ Where it's heading
The AI work is converging on conversational realism — waiting for the sender to finish, knowing why it was handed a conversation, rendering attachments the way a person would. That is a different problem from prompt quality, and it is the one that decides whether customers can tell they are talking to an agent. Channel work continues in parallel, tracking whatever Meta ships.
◆ Prediction
With wait time currently limited to chat conversations, extending it to follow-ups and Actions is the obvious gap to close; expect the AI Agent event vocabulary to keep growing beyond assignment and reopen.
Ergo
2.5COMMS
Ergo keeps tracking IRCv3 upstream while quietly opening its history layer to real databases.
◆ Current state
Ergo ships roughly two releases a year, each announced as a release candidate about a week ahead of the final. The content is consistent: whatever IRCv3 specifications have firmed up since the last cycle, plus bug fixes and config-format adjustments. The one structural change in this window was pluggable history storage, which took Ergo off its embedded database as the only option.
◆ Where it's heading
This is a project with a stable release ritual and a narrow remit: be a modern IRC server that implements the spec correctly and runs as a single binary. Feature work arrives as specification support rather than product invention. The exception is the operational surface — history backends and the HTTP API — where Ergo has been steadily making itself easier to run alongside existing infrastructure instead of as a self-contained island.
◆ Prediction
The v2.19.0 final should follow its release candidate within a week or two on the established pattern; the config-format break flagged in that RC is the main thing operators will need to handle on upgrade.
