The right move here is solving the agent plumbing problem nobody talks about — platforms like iMessage, WhatsApp, and Telegram each have their own quirks and nobody wants to rewrite delivery logic four times just to reach users who won't download a new app anyway. Spectrum's bet that the next wave of agents lives in messaging apps people already have is the right framing, and making that work across all those interfaces with one API instead of four separate integrations is genuinely useful. The free tier is strategic too — get devs hooked on the API, then scale them to Pro when they're building for real, and the open-source angle means they're not blindly trusting a black box. 166 upvotes and 224 followers for a 4-person team is low-key solid early signal.
