LiteLLM alternatives (2026)
LiteLLM: MIT LLM gateway. Self-host free; Enterprise SSO/governance is paid.
Its Catch: Vs OpenRouter/provider SDKs: self-host gateway you operate — not a hosted model marketplace.
Below: 8 free or free-tier tools from the same category (agent orchestration tools), free and open source first, then the closest match by shared tags. Each keeps its own Catch.
Free / OSS · Apache-2.0 · 5.6k GitHub stars
VerdictApache-2.0 filesystem-first agent framework when you want a Vercel-native, readable agent project — Gateway by default, beta APIs, star heat ahead of maturity.
CatchModel strings default to Vercel AI Gateway IDs; direct OpenAI and Anthropic helpers are built in, but any other provider means installing an AI SDK provider package and editing `agent.ts`. Public beta under Vercel beta terms — expect API churn. ★ is climbing far faster than a repo created in June 2026 with 1,000+ open issues and pull requests would suggest — judge it on substance (Vercel backing, shipping cadence), not the badge. Vs mastra (TypeScript agent framework, provider-neutral) and voltagent (TS framework + observability console): eve is the filesystem-convention, Vercel-native lane.
Free / OSS · Apache-2.0 · 27.4k GitHub stars
VerdictThe SDK for AI applications in the Next.js ecosystem.
CatchVercel-optimized, which is great on Vercel and requires more work elsewhere. Abstraction means some provider-specific features are harder to access.
Free / OSS · OSS/MIT · 148k GitHub stars
VerdictEssential for complex LLM apps, overkill for simple ones.
CatchAbstraction layers add complexity. Simple use cases feel over-engineered, and the learning curve is steeper than rolling your own for basic RAG.
Free / OSS · OSS/MIT · 52.6k GitHub stars
VerdictThe best data plumbing for LLM applications.
CatchThe abstraction layers can be confusing. Index, query engine, retriever, synthesizer—the terminology requires investment to master.
Free / OSS · Apache-2.0 · 29.9k GitHub stars
VerdictApache-2.0 code-first agents. Free library; sandbox/ops are yours.
CatchMinimalist — not Temporal durable workflows or production multi-tenant agent platform. Code execution needs sandbox discipline. Vs CrewAI/PydanticAI: HF Hub gravity, less enterprise packaging. You own evals, memory, and deploy.
Free / OSS · Apache-2.0 · 42.8k GitHub stars
VerdictApache-2.0 Python agents + AgentOS. Ship on Agno, not Phidata nostalgia.
CatchVs LangGraph (graphs), CrewAI (roles), Mastra (TypeScript): Agno is Python performance + AgentOS productization, not a coding CLI like Claude Code/OpenCode. Phidata docs/imports are dead—use Agno. Control Plane and hosted conveniences are optional; day-one is OSS SDK+runtime you operate.
Free / OSS · OSS/MIT · 10.8k GitHub stars
VerdictMIT TypeScript agent framework. VoltOps optional; core is the gem.
CatchVs Mastra (TS runtime) and CrewAI/Agno (Python): VoltAgent is TS framework + platform surface, not a terminal coding agent. VoltOps is the paid/hosted ops layer; core stays MIT. Framework lock-in applies — you are building agents, not buying Claude Code.
Free / OSS · Freemium · 30.6k GitHub stars
VerdictFreemium agent tool/auth fabric. Great connectors; you rent the OAuth middle.
CatchVs github-mcp (one official GitHub surface) and raw MCP servers: Composio is a multi-app auth/tool platform — you depend on their connector quality and hosted auth. Free tier exists; production is seat/usage freemium. Not a coding agent and not a browser fleet.
