RivalryRadar is online competitor monitoring software for small SaaS teams. Add the competitors you care about, and it checks their homepage, pricing page and changelog. It ignores noise like dates and counters, labels each real change (pricing, plan limits, features or messaging), and explains in plain English what it means for you. You get a digest by email, and the Team and Agency plans also post to Slack. Plans: Free (2 competitors, monthly digest), Solo $9.50/mo (5 competitors, weekly), Team $24.50/mo (15 competitors, daily plus Slack), Agency $74.50/mo (50 competitors, daily plus Slack). There's also a free one-off sample report on any competitor, no account needed.
