What is SimpleX Chat?

SimpleX Chat stabilizes its 6.5 line, routing link previews through SOCKS for privacy.

SimpleX Chat, the messenger built without user identifiers, is rolling out its 6.5.x line. Recent changelog activity is dominated by per-architecture armv7a build tags that merge stable into the Android branch — release plumbing rather than new capability. The one substantive change sits in the 6.5.0 beta: routing link previews through the SOCKS proxy when enabled, plus a UI to switch toolbar position.

What is Heymarket?

Heymarket evolves from team SMS into an AI-agent messaging platform.

Heymarket has shipped a string of real product features — Escalations, inbound webhooks, Conversation Tags, Salesforce/HubSpot email — and is now publicly building AI agents that handle customer messaging, with the team using its own product as the first deployment site. The platform is moving past 'business texting' into multichannel customer messaging with structured workflows and automation primitives.

SimpleX Chat vs Heymarket: editorial side-by-side

S5.0

SimpleX Chat stabilizes its 6.5 line, routing link previews through SOCKS for privacy.

◆ Current state

SimpleX Chat, the messenger built without user identifiers, is rolling out its 6.5.x line. Recent changelog activity is dominated by per-architecture armv7a build tags that merge stable into the Android branch — release plumbing rather than new capability. The one substantive change sits in the 6.5.0 beta: routing link previews through the SOCKS proxy when enabled, plus a UI to switch toolbar position.

◆ Where it's heading

The cadence reflects a stabilization phase on 6.5 — frequent point tags across architectures over a stable feature base. The privacy-by-default ethos still shows in the lone real feature, SOCKS-proxied previews. Expect continued 6.5.x hardening rather than directional change.

◆ Prediction

Next moves are likely more 6.5.x point releases and architecture builds; the beta channel, not the armv7a stable tags, is where the next feature batch will surface.

H6.3

Heymarket evolves from team SMS into an AI-agent messaging platform.

◆ Current state

Heymarket has shipped a string of real product features — Escalations, inbound webhooks, Conversation Tags, Salesforce/HubSpot email — and is now publicly building AI agents that handle customer messaging, with the team using its own product as the first deployment site. The platform is moving past 'business texting' into multichannel customer messaging with structured workflows and automation primitives.

◆ Where it's heading

Each release stacks toward a coherent thesis: omnichannel inbox plus tagging plus escalation routing plus webhooks adds up to the platform substrate an AI agent needs. The 'eating our own dogfood' post on AI agents confirms agents are now in production internally, which is a stronger signal than a marketing launch. Heymarket is positioning to be where SMBs run customer messaging end-to-end, with humans handling exceptions the agents escalate.

◆ Prediction

Expect a public-facing AI agents launch in the next quarter — likely a packaged product with deflection rate or response-time SLAs as the headline metric. Pricing change toward usage-based components (per-resolution or per-conversation) would be the natural follow-on as agent costs become the dominant unit economics question.
