Features and specs

What each product offers, as listed by its team.

https://open-gpt.app/ 5 features
Rylvo 15 features
  • Accessible AI Chat Interface
    Provides a user-friendly web-based interface for interacting with GPT-based AI models without needing to set up API access or coding knowledge.
  • No Installation Required
    Being a web application, it can be used directly from a browser without downloading or installing any software.
  • Potentially Free or Low-Cost Access
    Many GPT wrapper sites like this offer free tiers or lower-cost access compared to official API pricing, making AI chat more accessible to casual users.
  • Quick Setup
    Users can typically start chatting almost immediately after visiting the site, with minimal account creation or configuration steps.
  • Cross-Platform Compatibility
    Since it runs in a browser, it can be accessed from various devices including desktops, tablets, and smartphones without platform-specific versions.

Possible disadvantages

  • Uncertain Reliability
    Third-party GPT wrapper websites often depend on underlying API access that can be unstable, rate-limited, or discontinued without notice, affecting consistent availability.
  • Data Privacy Concerns
    Using an unofficial third-party service to process conversations raises questions about how user data and conversation history are stored, used, or shared.
  • Limited Transparency
    It may be unclear which underlying AI model version is being used, how up-to-date it is, or what modifications have been made to the base model's behavior.
  • Potential Hidden Costs or Ads
    Free-to-use AI wrapper sites often monetize through ads, premium upsells, or data collection, which may not be clearly disclosed to users upfront.
  • Lack of Official Support
    Unlike official AI platforms, unofficial wrapper sites may lack dedicated customer support, regular updates, or accountability if issues arise.
  • Bring Your Own LLM Key (BYOK)
    Run bot chat and every AI feature on your own OpenAI, Anthropic, Gemini or OpenRouter key. Unlimited token usage, zero markup — you pay only for platform capacity.
  • Multi-Agent Orchestration
    Route work across specialist agents with shared state, nested traces and per-agent cost attribution.
  • Guardrails & Approval Routing
    Policy checks run before a response ships. Risky tool calls and actions route to a human for approval first.
  • Human-in-the-Loop Takeover
    Operators watch live sessions in real time and take over mid-conversation without dropping context.
  • Full Trace Observability
    Every turn logged span by span: prompt, retrieval, tool calls, tokens, latency and cost.
  • Knowledge Base / RAG
    16 knowledge-source types and 12 retrieval blueprints, with citations preserved through to the answer
  • MCP Server Management
    129 MCP tools. Govern Model Context Protocol servers with a credential vault and guardrails, or expose any bot as an MCP server.
  • Multi-Channel Deployment
    13 channels: WhatsApp, Slack, Telegram, Discord, Microsoft Teams, Messenger, Instagram, SMS, LINE, inbound email and web widget.
  • Agent Testing & Evaluation
    Versioned test suites with LLM-judge scoring. Regression-check an agent before it reaches production.
  • Automated Failure Detection
    Detects failures in live production traffic and proposes fixes before customers report them.
  • Prompt Versioning & A/B Testing
    Version, compare and auto-optimize system prompts against real conversation history.
  • Test & Production Environments
    Separate test and production environments with gated promotion between them.
  • Prebuilt Agent Templates
    29 templates that ship fully built with prompts, guardrails, connectors, knowledge base, scheduled tasks and test cases.
  • Bring Your Own Database
    Sync conversation data into your own Postgres or MongoDB, or dispatch events to a webhook.
  • REST API & Webhooks
    Public bot-run API with idempotency keys, per-key rate limiting and signed webhooks.

Your AI Stack Is the Problem - Meet Rylvo

Questions & Answers

As answered by people managing https://open-gpt.app/ and Rylvo.

What makes your product unique?

Rylvo's answer:

Rylvo runs on your own LLM key. Bot chat and every AI feature - prompt optimization, red teaming, evaluation, embeddings - execute on your OpenAI, Anthropic, Gemini, or OpenRouter key with zero markup and unlimited token usage. There are no credits and no wallet. You pay a flat subscription for platform capacity, and your model spend stays between you and your provider.

The second difference is scope. Most tools cover one stage of the agent lifecycle: a builder, or an observability layer, or an eval harness. Rylvo covers the whole loop in one place - build from 29 prebuilt templates, ground on a knowledge base with 16 source types, govern with guardrails and human approval routing, deploy to 13 channels, trace every turn span-by-span, and catch failures in production traffic automatically. The agent you test is the agent you ship, and the trace that explains it lives in the same system.

What's the story behind your product?

Rylvo's answer:

Rylvo started with a frustration that anyone shipping AI agents recognizes: getting a demo working takes an afternoon, and getting it trustworthy in production takes months of duct tape. Observability in one tool, evaluation in another, guardrails hand-rolled, and a bill from a platform charging a margin on top of the model provider you were already paying.

So Rylvo was built as one system instead of four, on a principle that shows up everywhere in the product: you bring your own model key, your tokens are unmarked-up and unmetered, and your conversation data can live in your own database. The platform earns its subscription on capability, not on a cut of your inference spend.

Why should a person choose your product over its competitors?

Rylvo's answer:

Because you stop stitching four tools together, and you stop paying a margin on tokens you already pay a model provider for.

Observability platforms like Langfuse and Humanloop tell you what happened, but you still need a separate stack to build, govern, and deploy the agent. Agent builders like Relevance AI and Dify get you to a working bot quickly, but production governance - guardrails before a response ships, human approval on risky actions, gated promotion between test and production environments - is where they thin out. Microsoft Copilot is strong if you live inside the Microsoft stack and are content with its models; Rylvo is model-agnostic and channel-agnostic by design.

Rylvo is one platform for the full lifecycle, with span-level traces and per-agent cost attribution across multi-agent runs, 129 MCP tools and a governed MCP hub, and conversation data you can sync into your own Postgres or MongoDB. A free tier is available and paid plans start at $40/month, with your LLM usage unmetered on your own key.

How would you describe the primary audience of your product?

Rylvo's answer:

Engineering and product teams putting AI agents into production, rather than prototyping them.

The typical user has already built something with an LLM, shipped it, and hit the problems that follow: no idea why the agent answered the way it did, no way to stop it doing something risky, no regression test before a prompt change goes live, and a model bill that grows faster than usage explains. They need traces, guardrails, evaluation, and cost control - not another way to prototype.

That spans solo developers and small teams on the Free and Lite tiers running a handful of bots, up to enterprises on Team and Enterprise plans running multi-agent operations across many channels with SSO and multi-region requirements. Support, operations, and internal-tooling use cases are the most common, but the platform is domain-agnostic.

Which are the primary technologies used for building your product?

Rylvo's answer:

Backend: Python with FastAPI, LangGraph for the agent execution engine, and durable LangGraph checkpoints in PostgreSQL. Pydantic for schema validation, SQLAlchemy and asyncpg for data access, structlog for structured logging.

Data: Firestore for application state, PostgreSQL for observability and trace storage, Qdrant for vector search in the knowledge base, and Redis for caching. Conversation data can also be synced to a customer's own PostgreSQL, MySQL, or MongoDB.

Frontend: Next.js 16 and React, with Firebase Authentication and real-time Firestore subscriptions in the operator dashboard.

Infrastructure: Google Cloud Run for the engine API, Firebase App Hosting for the web application, and Google Cloud Pub/Sub for asynchronous work.

Interoperability: the Model Context Protocol (MCP) throughout - Rylvo both governs external MCP servers and can expose any bot as one.
