  • Free Tier Limitations
    The free tier has significant limitations, including restricted CPU time and storage space, which can hinder more demanding applications.
  • Performance
    Shared plans might experience slower performance during peak times due to the shared nature of the infrastructure.
  • Lack of Root Access
    Users do not have root access to the underlying system, which can be a limitation for deploying certain types of applications or custom services.
  • Support Limitations
    While it offers community support and documentation, the level of professional support might not meet the needs of all users, especially those on lower-tier plans.
  • Limited Language Support
    Primarily focused on Python, which may not suit all projects, especially those requiring multi-language support.
  • Resource Constraints
    Lower-tier plans have stringent resource limits (CPU, RAM, storage), which can be restrictive for resource-intensive applications.

  • 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 โ€” step by step. - Source: dev.to / 10 days 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 โ€” prompts, completions, latency, token usage, cost โ€” 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 / 29 days 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 / about 1 month 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. Adds a network hop.... - Source: dev.to / about 1 month ago
  • Per-user cost attribution for your AI APP
    Same approach works with Langfuse, Phoenix, Braintrust, or your existing OTel pipeline โ€” the metadata.userId pattern is the universal part. - Source: dev.to / about 2 months ago

  • [Offer] I need someone to set up a webhook in my WordPress site and a Python server with listener + bot
    The website is already built. Each comment will have a reddit post URL, and the bot should leave a comment on that URL. We can use pythonanywhere.com for this to make it easiest. Source: about 3 years ago
  • Flask and web hosting
    If you are learning, use pythonanywhere.com as they specialize in python, and make setup easy. Only $5 a month. Start with a barebones flask app, get it to run, then follow a tutorial. Actually better to build the app locally, easier to test with IDE like Pycharm. Then upload to the net. Source: about 3 years ago
  • Redirecting client to my server via a external server
    Hello, I have a Minecraft server running on a Rpi with Paper. It works great and I use it to play with some of my friends. However, the server's public IP address often changes, meaning that I have to give my friends the new IP address daily. Being a programmer, I feel this could be automated. I don't want to buy a domain, so I want to try and setup a system where the server sends Its IP to my PythonAnywhere... Source: about 3 years ago
  • Question Gallery WebApp Django or Flask?
    Hosting wise, I would reccomend pythonanywhere.com, combined with either https://imagekit.io or https://cloudinary.com. Source: about 3 years ago
  • Cheap Heroku alternative for PHP MySQL app
    So what is the best alternative? I have one Plotly Dash app on pythonanywhere.com where I spend 6 bucks a month so I don't want to spend anymore than 5 dollars per month on the PHP + MySQL. Source: about 3 years ago
