What is Signal Desktop?
Signal Desktop's 8.36 beta adds favorite sticker packs after a fix-only week.
Signal Desktop ships a beta roughly weekly, and most builds since September carry only generic fix notes. v8.36.0-beta.1 adds favorite sticker packs, so the ones a user relies on stay at hand. It follows the fix-only v8.35.0-beta.1 and v8.34.0-beta.1, which added contact sharing from desktop and better audio device handling.
What is SuprSend?
Notification infra platform invests in developer ergonomics — MCP, CLI, Templates 2.0, OTEL.
SuprSend has been shipping for a developer-first audience: Templates 2.0 with variants and a redesigned editor (one template per channel, with tenant/language/plan branches), a programmatic Messages API for fetching and updating delivery state, zero-install CLI and MCP server via npx, native monitoring integrations for Datadog, New Relic, and OpenTelemetry. CLI updates also added automatic SKILLS.md generation and fixed a corrupted Node SDK package-lock.

Signal Desktop
5.0COMMS
Signal Desktop's 8.36 beta adds favorite sticker packs after a fix-only week.
◆ Current state
Signal Desktop ships a beta roughly weekly, and most builds since September carry only generic fix notes. v8.36.0-beta.1 adds favorite sticker packs, so the ones a user relies on stay at hand. It follows the fix-only v8.35.0-beta.1 and v8.34.0-beta.1, which added contact sharing from desktop and better audio device handling.
◆ Where it's heading
The desktop app is closing gaps with mobile one feature at a time, separated by maintenance betas. Visible features arrive about every two to three builds.
◆ Prediction
The next feature beta is likely within one or two builds, based on the cadence since October. The entries don't indicate what it will contain.
SuprSend
5.0COMMS
Notification infra platform invests in developer ergonomics — MCP, CLI, Templates 2.0, OTEL.
◆ Current state
SuprSend has been shipping for a developer-first audience: Templates 2.0 with variants and a redesigned editor (one template per channel, with tenant/language/plan branches), a programmatic Messages API for fetching and updating delivery state, zero-install CLI and MCP server via npx, native monitoring integrations for Datadog, New Relic, and OpenTelemetry. CLI updates also added automatic SKILLS.md generation and fixed a corrupted Node SDK package-lock.
◆ Where it's heading
SuprSend is positioning as the notification infrastructure that backend engineers — and the AI coding agents working on their behalf — actually want to use. The MCP-server and CLI-via-npx work, plus Claude Code plugin refresh, signal a deliberate AI-native posture. Templates 2.0 is the structural play: one template that resolves to the right variant per tenant/language/plan removes a real maintenance burden for multi-tenant SaaS and i18n use cases, which is where notification infra usually breaks down at scale.
◆ Prediction
Expect deeper Inbox/in-app notification primitives now that the Messages API is programmatic, more advanced Templates 2.0 variant logic (likely conditional fragments and content reuse), and broader observability surface — possibly per-workflow SLO tracking. Continued investment in MCP/agent-callable workflows is highly likely.
