## LiteLLM

LiteLLM is an open-source AI gateway and Python SDK designed to remove vendor lock-in from LLM applications. The SDK lets you call models from OpenAI, Anthropic, Google Vertex AI, Bedrock, Mistral, Azure and dozens of other providers using the same OpenAI-style request format, so switching models is a configuration change rather than a code rewrite. The same project ships an AI Gateway (often called the proxy) that turns that abstraction into a shared service for an entire organization.

That gateway is where most platform teams find the value. It issues virtual keys scoped by team, project or application, tracks spend per key against budgets, applies rate limits (TPM and RPM), and exposes dashboards for request volume, token usage and cost per model. Routing features include load balancing across deployments, automatic fallbacks when a provider fails, retries and budget-based rerouting, plus guardrails for PII masking, prompt-injection detection and secret detection.

The project is genuinely open source with the code on GitHub (BerriAI/litellm) and a very active community. Enterprise features add SSO, audit logs, and support for agents and MCP servers through the same gateway. Notably, LiteLLM supports day-zero access to new models so teams can adopt them as soon as they ship, and it can also serve self-hosted, fine-tuned and internal models behind the same key. Companies cited on the site include NVIDIA, Netflix, Okta, Lemonade and AT&T.

**Pricing & Plans:** Freemium and open source. The self-hosted LiteLLM gateway and SDK are free under an open-source licence, and a free tier lets you get started immediately. Enterprise plans with SSO, audit logs, SLAs and advanced support are quoted on request via the sales team.

- **OpenAI-compatible API for 100+ LLMs:** Call 100+ providers and 1,800+ models using one request format, so you can swap models without changing application code.
- **Virtual keys, teams and budgets:** Issue scoped keys per team, project or app, set monthly spend caps and see exactly who is driving usage and cost.
- **Routing, load balancing and fallbacks:** Distribute traffic across deployments, retry on failure and automatically fall back to another model or provider when one goes down.
- **Observability and spend tracking:** Dashboards for request volume, tokens and cost per model, with support for logging and analytics integrations.
- **Guardrails and policy controls:** Plug in PII masking, prompt-injection detection and secret-detection guardrails, and manage policies centrally instead of in every app.

**Strengths:** Truly open source with a large GitHub community and self-hosting option; Very broad provider coverage with an OpenAI-compatible interface; Enterprise-grade controls: virtual keys, budgets, rate limits and audit logs; Day-zero support for new models and easy fallback when providers fail

**Limitations:** Self-hosting means you own deployment, upgrades and uptime; Feature depth varies between the free open-source version and enterprise plan; The breadth of configuration options can be overwhelming for small projects

## Treg

Treg acts as a unified credential and routing layer for AI agents. Instead of signing up for dozens of SaaS APIs, you connect your agent to one MCP server and receive a single treg token that answers for every tool in the catalog. The catalog spans SEO keyword and rank tracking, backlink analysis, AI search visibility, social media and advertising data, lead enrichment, email verification, company data, web scraping, and AI video, image, and voice generation.

A core idea is evidence-based tool selection. Multiple providers often sell the same capability - nineteen sell backlinks, nine sell email lookup - so treg shows each one's listed price alongside measured success rate, speed, and last-answer time, letting the agent pick a vendor on data rather than guesswork. Pricing is pay-per-result with the cost quoted before each call, funded by a starting balance, and there is no subscription required for tools you'd otherwise buy seats for.

For teams that already pay providers directly, treg supports bring-your-own-key (BYOK): your own keys route first and run unmetered, while credentials are injected server-side so raw keys never sit on a machine. It is fully open source under Apache 2.0, integrates with coding agents and automation workflows, and lets orgs publish internal SKILL.md-based tools to teammates by token.

**Pricing & Plans:** Pay-per-call with no subscription; prices are quoted before each call and start with $1.00 of free credit. Bringing your own provider keys makes those calls unmetered.

- **One key, 127 providers:** A single treg token routes to 4,100+ endpoints across 127 providers, so no per-provider signups or scattered key files.
- **Evidence-based provider comparison:** See each provider's price plus measured success rate, speed, and last-answer time, and pin a preferred vendor when you want.
- **Pay-per-call pricing:** Pay fractions of a cent per call with the price shown before you commit, no monthly seats required.
- **Bring your own keys (BYOK):** Route calls through your existing provider keys at no markup; credentials are injected server-side and never stored on a machine.
- **Open source and agent-ready:** Apache 2.0 licensed with MCP support, coding-agent integration, and the ability to publish your own SKILL.md tools.

**Strengths:** Single key across 4,100+ endpoints and 127 providers; Transparent pay-per-call pricing quoted before each call; Measured success rate and latency help pick the right vendor; Open source (Apache 2.0) with BYOK and server-side credential injection

**Limitations:** The breadth of the catalog can be overwhelming for newcomers; Coverage and reliability depend on the many third-party providers behind it; Usage is metered, so heavy callers still accumulate real costs
