Top 5 LiteLLM Alternatives in 2026

1. 01

   Self-host proxy is your operational burden

   The OSS proxy is real production software with a Postgres database, a Redis cache, a fallback config, a retention policy, and a deployment story. Outages happen at your timestamp, not vendor's. Version upgrades require schema migrations. Secrets rotation needs to round-trip through every key the proxy stores. Pre-PMF startup teams discover that the 3am page when the proxy is wedged is now their problem to solve.

2. 02

   Per-LLM config drift

   Each new LLM you add to the proxy needs a registry entry — model name, provider key, context length, price snapshot. When upstream providers rename a model (gpt-5 → gpt-5-2026-05), change context length, or update pricing mid-month, the config drifts unless someone on your team owns the sync. The community-maintained `model_prices_and_context_window.json` helps, but production deployments still need manual review on every upstream change.

3. 03

   Enterprise pricing is contact-sales only

   OSS is free, but the Enterprise tier with JWT auth, SSO, audit logs, and SLAs requires a sales call. There is no public list price. For procurement workflows that need a budget estimate before a sales call can be scheduled, the absence of a list price is a real friction point — and it pushes some teams toward hosted competitors who publish their tiers openly.

   Multimodal billing isn't the proxy's centerpiece

   LiteLLM's identity is OpenAI-shape unification across LLMs. Image generation, video generation, and audio synthesis can be called through the proxy, but they sit outside the chat completions shape that the product optimizes for. Per-call image billing and per-second video billing both work, but they read as adapters rather than first-class concepts. Teams that built a Stripe-style billing pipeline around LiteLLM's per-token spend model usually have to extend it manually for image and video.

   ElliotGate

   Editor's pick

   Visit site

   Managed gateway with OpenAI + Anthropic native protocols, curated multimodal catalog, and zero self-host ops.

# LiteLLM proxy (before — self-hosted)
- base_url: http://litellm-proxy.internal:4000/v1
- api_key:  $LITELLM_VIRTUAL_KEY
- config:   ./litellm_config.yaml   # per-LLM model registry

# ElliotGate (after — managed)
+ base_url: https://api.elliotgate.com/v1
+ api_key:  $OMINIGATE_API_KEY
# No config file — model registry lives server-side and stays in sync.

The per-LLM config file becomes a server-side registry. You lose the customization knob, you gain the sync responsibility.
