We run OpenTelemetry-based tracing that instruments LangChain and most other frameworks, so you get spans, latency and token cost from day one whether you stay on langchain or keep your custom TS runtime. Evals sit on the same traces, so you can score grou",

Back then pre Claude code dev was kind of a nightmare, every customization was hidden behind layers of abstractions in langchain and features/changes took a while. Spent the last two years in a custom typescript runtime for agents, no frameworks, all custom handcrafted code, and then of course assisted by Claude/Codex.\n\nI am building something new 0 to 1 and curious about the experience if I return to building on the langchain stack, what are the pros/cons versus custom agnostic code, or using vercel SDK etc. Things I care about are easy model provider swapping, observability day 1, evals, human-in-the-loop, and ZDR/HIPPA compliance. Also from a dev hiring perspective, curious on the sentiment of TS v Python for agents in 2026. Is langchain/deep agents TS on par?\n\nLots of questions, happy to hear general perspective or get into specifics, appreciate any insight!",
