Description from the maker (original English)
OpenAI-compatible MCP gateway cataloging 22 LLM providers, with routing, failover, and tools.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Compared only with servers in this prototype, not the whole registry.
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

freellmpool catalogs 23 LLM providers as distinct groups spanning recurring free tiers, keyless endpoints, finite trials, pin-only routes, and disabled candidates. It exposes 178 enabled chat routes and 443 cataloged chat models, and automatically pools only enabled routes you can access behind one OpenAI-compatible endpoint — as a CLI, a Python library, or a local proxy. It can start without credentials when an enabled keyless route is available.

pip install freellmpool and uvx freellmpool install the audited provider catalog, bounded streaming and sentinel hardening, Hermes profile, proxy readiness/provider APIs, spread routing, and OpenCode registry-readiness hardening.opencode-freellmpool and opencode-freellmpool-tui are tested but not published on npm as of 2026-08-29. Use their repository-local installation instructions for now.Fresh install to first free-model reply is measured at about 19 seconds under the 30-second target on a clean Linux/Python 3.12 environment, with no API keys when a keyless provider is up:
# One command when uv is installed; no checkout or manually managed virtualenv:
uvx freellmpool ask --max-tokens 32 "Reply with one short sentence: freellmpool is ready."
Portable virtual-environment path:
python3 -m venv .venv
. .venv/bin/activate python -m pip install --upgrade pip python -m pip install freellmpool freellmpool ask --max-tokens 32 "Reply with one short sentence: freellmpool is ready."
CI runs the same path from this checkout with FREELLMPOOL_QUICKSTART_PACKAGE=. scripts/quickstart-test.sh.
The catalog covers provider-operated free tiers, keyless routes, and a few explicit finite-trial or disabled candidates. Eligibility and limits differ by provider. freellmpool automatically uses only enabled routes you can access, fails over when one is rate limited or down, and tracks local per-day usage.
Several providers (Pollinations, OVHcloud, and Kilo Gateway) need no API key, and LLM7 works without one, so the quickstart can answer without signup when a keyless provider is available.
To inspect your local provider keys, agent CLIs, proxy config, and Tailscale state before wiring tools, run the print-only init wizard:
freellmpool init --yes
freellmpool init --yes --agent opencode freellmpool init --yes --agent metaswarm --tailnet
Add keys for the other providers to unlock more models and higher limits.
LM Studio, Ollama, and llama.cpp can be previewed from a fixed list of literal loopback endpoints without scanning your LAN or processes:
freellmpool local discover
freellmpool local discover --name lm_studio freellmpool local import --name lm_studio --yes freellmpool ask --providers local_lm_studio --model " " "hello"
Discovery is read-only. Import is a separate affirmative step, writes no credential, and keeps every imported model out of automatic routing (auto = false). freellmpool local remove local_lm_studio --yes reverses only the block managed by the importer. Custom endpoints must be canonical literal loopback URLs such as http://127.0.0.1:1234/v1; hostnames, LAN addresses, redirects, and broad network scans are rejected.
freellmpool initfreellmpool init inspects provider keys, installed agent CLIs, Tailscale state, and proxy config, then prints one copy-pastable next step without editing files. Run it detect-only first:
freellmpool init --yes
--json emits the same detection as versioned JSON for scripts and agents.
Serve the proxy on your Tailscale 100.x address with a generated API key:
freellmpool tailnet serve --port 8080
From a remote machine:
freellmpool tailnet connect <tailnet-ip> --port 8080
Both sides support --api-key if you want to pin a key instead of using a generated token. Tailnet serving requires auth by default; do not run unauthenticated over non-loopback interfaces.
This project uses one Umans/Kimi K2.7 worker lane, one MiniMax M3 lane, Codex as escalation, and Claude Opus only for final pre-ship review. The installable Metaswarm profile mirrors that posture: one free/cheap worker lane through the local proxy, one larger freellmpool reviewer lane, and Codex/Opus as explicit user-owned paid escalation/final-review lanes only (never silent).
freellmpool init --yes --agent metaswarm --tailnet
freellmpool profile install metaswarm freellmpool tailnet serve --port 8080 freellmpool profile doctor metaswarm --dry-run
freellmpool's proxy speaks the OpenAI API and includes an experimental Anthropic-compatible path, so coding agents can run against pooled free tiers — just point them at the proxy:
freellmpool proxy # starts http://localhost:8080
freellmpool code claude # prints the one-line setup for Claude Code freellmpool profile list # richer installable profiles freellmpool profile show metaswarm # Tailnet-aware Metaswarm profile freellmpool profile install hermes # Hermes custom-endpoint config
The Hermes profile prints (and never writes) this supported custom-endpoint block; hermes model provides the interactive equivalent:
model:
provider: custom default: quality base_url: http://localhost:8080/v1 api_key: anything
Claude Code gateway mode can also be launched directly:
ANTHROPIC_BASE_URL=http://localhost:8080 \
ANTHROPIC_AUTH_TOKEN=dummy \ ANTHROPIC_API_KEY=dummy \ ANTHROPIC_MODEL=auto \ ANTHROPIC_SMALL_FAST_MODEL=auto \ CLAUDE_CODE_ENABLE_GATEWAY_MODEL_DISCOVERY=1 \ claude
Existing OpenAI-compatible apps work the same way: set OPENAI_BASE_URL=http://localhost:8080/v1 and keep your code unchanged. Anthropic-compatible tools can use the experimental bridge with ANTHROPIC_BASE_URL=http://localhost:8080.
Text-only /v1/responses and /v1/messages requests stream incrementally from the selected provider. Tool calls and richer content intentionally stay on the buffered compatibility path. The browser dashboard and playground share one public, data-free shell; when proxy auth is enabled it prompts for the bearer token and keeps it only in page memory while protected status, inventory, model, and battle calls continue to require the Authorization header.
OpenCode gets a deeper integration in 0.12.0: a live in-editor dashboard (routing mode, estimated savings, tokens served free, provider race, latency), per-request agent routing via the model picker (freellmpool/agent|spread|auto|fast|quality|fair), and freellmpool_status / freellmpool_models tools — see integrations/opencode-tui and the guide. The plugin registers its routing aliases automatically on supported OpenCode versions without rewriting user configuration. Restart OpenCode and check opencode models freellmpool. The package tarballs are validated in CI, but npm publication remains pending; the linked local-file instructions remain the working install path.
New in 0.11: capacity tools — freellmpool capacity status shows which free tiers are usable right now, freellmpool providers health live-probes them, and freellmpool keys add walks you through configuring more (see Capacity & provider health and docs/CAPACITY.md).
New in 0.10: an async API (AsyncPool), an MCP server (freellmpool mcp), latency-aware routing with freellmpool benchmark, observability hooks, and a plugin system for custom providers. See the changelog.
pip install freellmpool # or: pipx install freellmpool
Only dependency is httpx. Python 3.11+.
The published container runs the local proxy as an unprivileged user. Persist quota, stats, route-health, cache, and configuration state in a named volume:
docker volume create freellmpool-data
docker run --rm -p 127.0.0.1:8080:8080 \ --volume freellmpool-data:/home/freellmpool/.config/freellmpool \ --env GROQ_API_KEY \ ghcr.io/0xzr/freellmpool:0.13.0
Omit --env GROQ_API_KEY if you want a credential-free start; the proxy can answer only while an enabled keyless route is available. Keep the published port on loopback. If you deliberately expose it, set FREELLMPOOL_PROXY_KEY and require that Bearer token from clients.
For the bundled Open WebUI stack, place any provider credentials in .env and run docker compose up -d. Compose waits for the proxy health check and keeps both freellmpool and Open WebUI state in named volumes; open http://localhost:3000 after both services are healthy.

freellmpool tokenmax is the tongue-in-cheek maximum-effort mode: it fans your prompt out to many available models at once and prints each answer. The CLI adds a synthesized verdict by default unless you pass --no-synthesize; the MCP tool returns the model answers for the calling agent to synthesize. (See docs/MCP.md.)
freellmpool stats is a running, persistent lifetime total (it survives restarts and upgrades). Embed freellmpool badge in a README, or use freellmpool badge --summary -o summary.svg for a larger card with tokens, requests, estimated savings, and provider mix. The proxy can serve both /badge.svg and /summary.svg live when FREELLMPOOL_PUBLIC_BADGE=1 makes public badges embeddable.
Pin a provider or model; common OpenAI/Anthropic model names are mapped to a free equivalent so existing scripts keep working:
freellmpool ask -m groq/openai/gpt-oss-20b "hi"
freellmpool ask -p cerebras,groq "hi" freellmpool ask -m gpt-4o-mini "hi" # routed to a free model
freellmpool roles lists ask-role presets (coder, critic, summarizer, grounded-reader, long-context, cheap, fast, second-opinion, ...). Each role sets routing, token budget, temperature, task intent, and system-prompt hints without inventing a second routing engine. Explicit flags (--model, --providers, --routing, --task, --max-tokens) win over role defaults.
