respan-gateway
One endpoint for every LLM vendor. Any SDK, any model, any tool. One Rust binary.
Runs with mockssource: GitHubhomepageRustApache-2.0commit c9e433b35c6f
Rust, Apache-2.0 licensed. The project labels itself: ai agents, ai gateway, anthropic, gemini, hacktoberfest, llm, llm gateway and llm proxy.
respan-gateway runs, with stand-ins for the services it depends on. An Argusic agent installed it in 9.5 minutes and hit 2 errors and fixed every one without help on a clean machine with no GPU, and the whole session was recorded.
respan-gateway 0.3.0 Python package installed and verified working against a mock provider; Rust binary v0.2.0 built from source and all 692 unit tests pass
What the agent ended up with on a clean machine, in its own words. How this is measured
Measured by Argusic on a fresh machine every time. Every number links to its evidence. Argusic Score 92 of 100 (the mean of this project's run scores).

What was measured
From the run that decided this verdict. Every line is a recorded value, not an estimate.
What went wrong, in the agent's own words
The agent's own words, worst first, never rewritten into advice.
- Ubuntu 24.04 system Python blocks pip install (PEP 668 externally-managed-environment)0.2 minutes
- Rust workspace default build includes Python extension crate which needs libpython3.12-dev for linking
- Install time
- 10 minutes
- Cold machine to finish
- 10 minutes
- Errors hit and fixed
- 2 hit, 2 fixed with no human help
- How the result was proved
- pip install succeeded; E2E Python test against mock provider exercised models listing (2 models), in-process chat completion via openai SDK, HTTP server endpoints /v1/models and /v1/chat/completions (all 200), and /healthz (200); Rust binary built from source and started listening; `cargo test --workspace --all-targets --all-features --exclude respan-gateway-python` passed: 63 suites, 692 tests, 0 failures

What was not measured
The other half, so you can see exactly how far this evidence goes. A gap is printed as a gap and never filled in.
- Peak GPU memory
- this ran on a CPU machine, so there was no GPU to sample
- Behaviour over a long run
- each attempt uses the smallest documented settings and a fixed time budget, so this measures whether it runs, not how it holds up under load
- Behaviour against real services
- this run was verified against stand-in services only

Replay the whole session, every command from a clean machine to this point.
How it was tested
One agent, one container, no human help. It installs the project the way its own documentation says to, runs it, and fixes what breaks. Everything below is recorded as it happened: the terminal session, the log and the exact commit. The full method.
Strengths and limits
Measured facts, not opinions. How this is written.
What went well
- Recovered from all 2 errors without a human stepping in, which says the failures are documented well enough to solve.
- Licensed Apache-2.0, as reported by its host.
What did not, or is not known
- Only reached a running state against stand-in services, so nothing here proves it works against the real ones.
- Took 9.5 minutes to install, slower than the median of the 99 comparable projects Argusic has measured.
- Measured once so far. A single attempt shows it can run, not that it runs reliably.
Of the 100 ai-agents projects Argusic has installed and timed, respan-gateway was the 62nd fastest to reach a running state, and 74 of 100 reached one at all.
Also tested, in the same area
Every one of these was installed and run by Argusic on a clean machine. Nothing appears here that was not tested.

[](https://argusic.com/subject/respan-gateway)Questions
- Does respan-gateway run?
- respan-gateway runs, with mocks standing in for external services. Argusic installed and launched it on a clean machine in 10 minutes, hitting 2 errors on the way, and recorded the session.
- How did Argusic test respan-gateway?
- On a fresh, disposable machine, with every command recorded and the repository pinned at commit c9e433b35c6f. One attempt is recorded, and the full method is on the methodology page.
- What did it cost to test respan-gateway?
- The run that produced this verdict cost $0.07: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
- How long does respan-gateway take to install?
- 9.5 minutes in the run that decided this verdict, from a clean machine to a running state. That is one measured attempt, not an average.
- Does respan-gateway need a GPU?
- Not to start. Argusic reached a running state on a machine with no GPU.
- What goes wrong when installing respan-gateway?
- 2 things broke in the recorded run, and 2 were fixed without human help. Each one, and the time it cost, is listed on this page.
- How does respan-gateway compare with the alternatives?
- Of the 100 ai-agents projects Argusic has installed and timed, respan-gateway was the 62nd fastest to reach a running state, and 74 of 100 reached one at all.
- Where is the evidence for respan-gateway?
- The recorded run is on this page, each linking to its full log and terminal recording, stored with a sha256 fingerprint so it cannot be quietly altered.
