Modern Web Development Focus
GhostDev appears to be a web development agency that focuses on modern technologies and approaches, offering contemporary solutions for clients looking to build or improve their digital presence.
Agency Model
As a development agency, GhostDev can provide a team-based approach to projects, meaning clients benefit from multiple skill sets and perspectives rather than relying on a single freelancer.

Possible disadvantages of GhostDev

Limited Public Reviews
GhostDev does not appear to have a large volume of publicly available client reviews or testimonials on major third-party platforms, making it harder for potential clients to assess their track record.
Smaller Agency Scale
As a smaller or newer agency, GhostDev may have limited capacity to handle multiple large-scale projects simultaneously, which could lead to longer timelines or availability constraints.
Limited Portfolio Visibility
It can be difficult to find an extensive public portfolio showcasing a wide range of completed projects, making it challenging for prospective clients to fully evaluate the breadth of their work.
Brand Recognition
Compared to more established web development agencies, GhostDev has lower brand recognition, which may require potential clients to do more due diligence before committing to a partnership.
Limited Public Information
There is relatively limited publicly available information about the agency's team size, specific technologies used, and detailed case studies, which may make it harder for clients to make informed decisions.

Your AI Agent Works in Dev. It Will Fail in Production. Here's the Math.
Langfuse and LangSmith exist for this. Use them. The 30 minutes you spend setting up observability saves you the 87 hours you'd spend debugging blind. - Source: dev.to / 3 days ago
Strands Agents + Langfuse Evaluations
In this project we will build a Python banking assistant agent using Strands Agents and make it observable and continuously evaluated using Langfuse — step by step. - Source: dev.to / about 1 month ago
Best AI Monitoring Tools in 2026: LLM, Agent, and MCP Observability Compared
Langfuse is the open-source standard for LLM observability. It traces every LLM interaction — prompts, completions, latency, token usage, cost — and provides the tooling to debug, evaluate, and optimize LLM applications in production. Think of it as "Datadog for LLM calls" with a focus on prompt engineering workflows. - Source: dev.to / 2 months ago
What is an LLM evaluation harness? A deep dive into lm-eval-harness
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 / 2 months ago
How to track LLM costs per customer in production
Gateway or proxy attribution. A reverse proxy in front of the model-provider API records the request, computes the cost, and exposes per-customer breakdowns. Open-source options include Helicone, LiteLLM, Langfuse, and OpenLLMetry. Hosted equivalents serve as the AI cost observability layer for teams that want centralized visibility: LangSmith, Datadog LLM Observability, Arize Phoenix.
