Turn any code snippet into an interactive flowchart you can actually read
Paste a snippet in Python, JavaScript, TypeScript, Java, C, C++, Go, Rust, and others to get an interactive diagram of its logic.
Generate flowcharts, sequence diagrams, class diagrams, and user-journey views depending on what you need to explain.
A written explanation accompanies each diagram so you can verify the AI's reading of the logic against your own.
Download results as PNG, SVG, or PDF, or share a link to the diagram with teammates and reviewers.

One open-source AI gateway for 100+ LLM providers
Call 100+ providers and 1,800+ models using one request format, so you can swap models without changing application code.
Issue scoped keys per team, project or app, set monthly spend caps and see exactly who is driving usage and cost.
Distribute traffic across deployments, retry on failure and automatically fall back to another model or provider when one goes down.
Dashboards for request volume, tokens and cost per model, with support for logging and analytics integrations.
Provides a massive hosted model catalog with instant access, but requires trusting a third-party platform instead of self-hosting.
#1
SpecialistHosts high-performance open-weight models directly on dedicated serverless infrastructure, but does not route across external providers.
#2Delivers automated model failover and budget governance through an API gateway, but with less open-source customization.
AI diagrams and technical design docs built from your code and systems

Unified LLM gateway with failover and analytics, but offers less robust open-source developer SDK support.

AI diagramming, mind mapping and project tools with 50,000+ templates

AI-powered visual collaboration for diagrams, mind maps, and charts
Offers advanced enterprise observability and guardrail tools, but lacks LiteLLM's lightweight self-hosted proxy simplicity.

Provides managed multi-provider AI routing and cost tracking, but lacks the native open-source flexibility of LiteLLM.
Free / Open-sourceAn open-source alternative for unifying LLM providers, but features a less extensive ecosystem of middleware integrations.

Free / Open-sourceOpen-source request routing with built-in evaluations, but has a smaller community and fewer pre-built provider connectors.
SpecialistExcels at request caching, monitoring, and cost analytics, but functions primarily as a proxy monitor rather than a router.
