What is Postiz?
Open-source social scheduler adding platforms and patching security, no big swings
Postiz is in steady maintenance mode in this window. The releases cover a new MeWe social integration (v2.21.0), two security-advisory fixes urging immediate upgrade (v2.21.3), and a small Stripe-config bugfix (v2.20.2). Incremental platform breadth plus security upkeep, no architectural moves.
What is Instantly?
Instantly is replacing the outbound SDR with an AI agent and wrapping it in intent signals plus heavy automation.
Instantly's recent run is dense with AI-driven outbound work. The AI Sales Agent ships as a drop-in, no-configuration outbound automation. Signals goes live in SuperSearch, surfacing buyer-intent context drawn from real company activity. The AI Reply Agent gains capabilities like no-show recovery. Automations gets time-based triggers, conditional branching, and a more usable canvas. Underneath, the developer surface widened with 10x API rate limits and new docs.

Open-source social scheduler adding platforms and patching security, no big swings
◆ Current state
Postiz is in steady maintenance mode in this window. The releases cover a new MeWe social integration (v2.21.0), two security-advisory fixes urging immediate upgrade (v2.21.3), and a small Stripe-config bugfix (v2.20.2). Incremental platform breadth plus security upkeep, no architectural moves.
◆ Where it's heading
The pattern is breadth-and-stability: adding supported social networks one at a time while closing security and billing-config gaps. Nothing here signals a shift in product direction; it reads as a self-hosted scheduler steadily widening platform coverage and hardening the deployment.
◆ Prediction
Expect more incremental social-platform integrations and routine security and billing patches. No directional change is visible in these entries.
Instantly
7.5MARKETING
Instantly is replacing the outbound SDR with an AI agent and wrapping it in intent signals plus heavy automation.
◆ Current state
Instantly's recent run is dense with AI-driven outbound work. The AI Sales Agent ships as a drop-in, no-configuration outbound automation. Signals goes live in SuperSearch, surfacing buyer-intent context drawn from real company activity. The AI Reply Agent gains capabilities like no-show recovery. Automations gets time-based triggers, conditional branching, and a more usable canvas. Underneath, the developer surface widened with 10x API rate limits and new docs.
◆ Where it's heading
Two reinforcing bets are visible. One: outbound is becoming agent-operated, with the AI Sales Agent and AI Reply Agent owning more of the funnel that human SDRs used to run. Two: the agent's inputs are being upgraded — Signals turn SuperSearch into an intent-aware prospecting surface, automations carry the operational logic. The combined effect is that Instantly is positioning as the closest thing to a 'press play and outbound runs itself' product in the market.
◆ Prediction
Expect deeper signal sources (job changes, hiring trends, technographic shifts) wired directly into AI Sales Agent triggers, and tighter feedback loops where the Reply Agent's outcomes update prospecting filters. The 10x rate-limit work suggests Instantly is preparing for downstream platforms and integrations to start writing into it at higher volume.
