Helicone takes the simplest possible approach to LLM monitoring: it's a proxy. Change your OpenAI base URL from api.openai.com to oai.helicone.ai, add your Helicone API key as a header, and every LLM request is logged — latency, tokens, cost, prompts, and completions. No SDK integration, no code changes beyond a URL swap. - Source: dev.to / 3 months ago

You're monitoring production traffic. You need Langfuse / Phoenix / Helicone / Braintrust for that. Online eval is a different problem class: implicit feedback, drift detection, hallucination rates on your data, not on HellaSwag. - Source: dev.to / 3 months ago

For many teams, especially those starting out or with simpler needs, commercial solutions like Portkey, Helicone, OpenPipe, or LiteLLM Proxy offer off-the-shelf capabilities that cover many common proxy use cases (caching, logging, cost tracking). NeuroLink itself can be seen as an SDK that complements these, allowing you to integrate with them or build similar features on top. - Source: dev.to / 5 months ago

TL;DR: Go with Langfuse if you want open-source and self-hosted. Pick Helicone if you want the fastest setup (2 minutes, no SDK). Stick with LangSmith if your stack already runs on LangChain. And if your org already pays for Datadog, their LLM module slots right in. - Source: dev.to / 6 months ago

Hey HN, we're Justin and Cole, the founders of Helicone (https://helicone.ai) or self-deploy with our new fully open-source helm chart (https://helicone.ai/selfhost). Yet even with detailed traces, probabilistic systems are notoriously hard to debug at scale. So, we released evaluators (either via LLM-as-judge or custom Python evaluators leveraging the CodeSandbox SDK - https://codesandbox.io/docs/sdk/sandboxes).... - Source: Hacker News / over 1 year ago

DevHelm monitors cloud-hosted applications from the outside and correlates their failures with the cloud services they depend on. It is not a CloudWatch replacement for host metrics. It is the black-box layer that answers "is my service actually working for users, and if not, is a vendor the reason?" Every monitor, including the free tier, supports HTTP checks with custom headers, request bodies, response body... - Source: dev.to / about 2 months ago

"I want the developer experience of open-source tools without the infrastructure overhead" If you value CLI-driven workflows, config-as-code (Terraform, SDKs), and API-first design — but don't want to maintain monitoring infrastructure — DevHelm's free tier gives you 50 monitors with flat pricing and no self-hosting. You get the same developer-centric experience without running the infrastructure behind it. See... - Source: dev.to / 3 months ago

If you're deploying AI infrastructure — MCP servers, LLM-powered APIs, autonomous agents — and need to monitor their health, availability, and performance, start with DevHelm's free tier. Set up monitors for your AI endpoints in under 5 minutes via the CLI or Terraform, and let Nighthawk handle incident investigation while you ship features. Add Langfuse for prompt-level tracing when you need visibility into what... - Source: dev.to / 3 months ago

If you need config-as-code and want monitors + status pages managed alongside your infrastructure — choose DevHelm. The CLI, Terraform provider, and SDKs mean your status page configuration lives in the same repo as your service definitions. When you add a new service, you add its monitor and status page component in the same PR. - Source: dev.to / 3 months ago

DevHelm is a developer-first monitoring platform built around flat-rate pricing and infrastructure-as-code workflows. Monitors, alert channels, notification policies, and status pages are all manageable through a CLI, Terraform provider, or Python/JS SDKs — the same tools your team uses for infrastructure provisioning. The platform covers HTTP, TCP, DNS, keyword, and SSL certificate checks with intervals down to... - Source: dev.to / 3 months ago
