  • 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.

Questions & Answers

As answered by people managing AI Security Gateway and PythonAnywhere.

Why should a person choose your product over its competitors?

AI Security Gateway's answer

AI Security Gateway offers a unique combination that no competitor matches:

  • vs. Portkey/Helicone: They observe and log. We actively redact PII, kill agent loops, and push webhook alerts โ€” before your data leaves your infrastructure.
  • vs. OpenRouter: They route traffic. We govern it โ€” with PII redaction, budget enforcement, loop protection, and EU AI Act compliant audit trails.
  • vs. Vercel AI Gateway: They passively log. We scan, redact, block, and alert in real time.
  • vs. LiteLLM: We add a built-in firewall, webhook notifications, compliance logging, and managed hosting.

Plus: EU AI Act Article 12 enforcement begins August 2, 2026. AISG ships compliant audit trails today โ€” hash-chained, tamper-evident, with JSONL export and chain verification. Most competitors have no compliance story at all.

How would you describe the primary audience of your product?

AI Security Gateway's answer

Software Architects, CISOs, and Engineering Managers at organizations moving LLM implementations from "experimentation" to "production." We serve teams that need to satisfy strict security and compliance reviews while simultaneously reducing the high cost of proprietary AI models. AI Security gateway is designed for developers, startups, and enterprises building applications with LLMs. It is especially valuable for teams moving from experimentation to production, where concerns around data security, compliance, and cost control become critical.

Which are the primary technologies used for building your product?

AI Security Gateway's answer

AI Security Gateway is built using a cloud-native architecture with Python-based API services, containerized deployments (ECS/EKS), and AWS infrastructure components such as NoSQL Databases and CDN. It leverages industry-standard NLP and security frameworks for detection and integrates with multiple LLM provider APIs through a unified, controlled and optimized gateway layer.

Who are some of the biggest customers of your product?

AI Security Gateway's answer

AI Security Gateway is currently being adopted by early-stage startups, independent developers, and AI-focused teams experimenting with production use cases. As the platform evolves, it is designed to support enterprise-grade deployments with advanced governance and compliance requirements.

What's the story behind your product?

AI Security Gateway's answer

AI Security Gateway (AISG) was built after observing a recurring pattern across teams adopting LLMs: developers were unknowingly sending sensitive data such as API keys, logs, and customer information directly to external AI providers, while also struggling with unpredictable costs. Existing solutions either focused on routing or security, but not both. AISG was created as a unified layer to solve these real-world problems โ€” enabling safe, controlled, and cost-efficient AI adoption. AISG was born out of a realization by its founder, a veteran software architect, that 'Shadow AI' was becoming the biggest security risk in the modern stack. After seeing users accidentally paste company secrets into AI prompts, we engineered a stateless, high-performance firewall to allow innovation to continue without compromising data sovereignty.

What makes your product unique?

AI Security Gateway's answer

Unlike standard AI gateways that act as passive proxies, AI Security Gateway is an active security and compliance engine. We combine:

  1. Multi-modal Vision DLP โ€” OCR scans images for PII before they reach any provider
  2. Recursive Loop Protection โ€” the only API proxy that detects and kills agent retry loops at the gateway layer, across all frameworks (LangChain, CrewAI, AutoGPT)
  3. Real-time Webhook Alerts โ€” HMAC-SHA256 signed push notifications to your SOC workflow. Most AI proxies require polling; AISG pushes events the moment they happen.
  4. EU AI Act Compliance โ€” hash-chained, tamper-evident audit records that satisfy Article 12 requirements. SHA-256 fingerprints only โ€” no raw content stored. Privacy by design.
  5. Financial Intelligence โ€” treats LLM tokens like a trading desk, routing each request to the cheapest provider in real time. All in a single stateless proxy with 2-line integration

  • I Built an Open-Source AI Firewall Because Every LLM App Leaks Data
    I built AI Security Gateway to fix this. It's an open-source proxy that sits between your app and any LLM provider. Every prompt passes through a security layer before it reaches the model. - Source: dev.to / 4 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: over 3 years ago
