Progress — the Telerik Parent — Entered LLM Observability With a Free Tier Aimed at Langfuse and Laminar
Progress launched AI Observability on Product Hunt August 7, 2026, hitting #5 with 110 upvotes: tracing, evaluation, and improvement for agents in production, with SDKs for .NET, Python, and JavaScript/TypeScript and a free plan requiring no credit card. Its pitch targets the failure mode traditional APM misses — runs that look successful but chose the wrong tool, ignored context, produced unsupported answers, or burned tokens in costly loops. The listed comparables are Langfuse, Laminar, Latitude, LangChain, and Dify, all startups. The signal is the .NET-first entry: an incumbent enterprise tooling vendor is defending its existing developer base by shipping observability into it, which is the cheapest incumbent counter-move available and the one that most reliably strands seed-stage tooling startups.
