Tokviz
waldekm · App
Tokviz is a local web dashboard for people building apps that call language models. It accepts OpenTelemetry traces, picks out the spans that follow the Gen AI conventions and shows token usage, cost, request counts and the models in use as they arrive. Overview, models and requests views let you drill down to the span attributes of each request. Nothing is written to a database or to disk, and the data is gone when you stop it.
Written by ooruby from the README of tokviz 0.3.10.

Why it's useful
You can see how many tokens each request uses, what it costs and which models are really being called, without setting up a database or Docker.
What you could do with it
- Point your OpenTelemetry exporter at it and watch token use and cost as your app makes LLM calls.
- Open the models view to compare request counts, input and output tokens and total cost for each model.
- Click a request to see every span attribute, along with its model, operation, tokens, cost and duration.
Written from its documentation: what it says it can do, not what our checks found.
Maintenance
Not measuredNo release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.
Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured
- Data handling disclosed
- finding
- no statement of what it reads, writes or sends (README.md)
Published because it was found. A finding is information about where the limits are, not a verdict that the software is unsafe.
What this does not cover
- Everything. Treat it as you would software from anywhere else.
Receipt history: every signed receipt for every version of this listing, and what changed between them.
In its maker's words
Real-time, local-only web dashboard that visualizes LLM token usage and costs from standard OpenTelemetry data

Static scanned
- What it establishes
- Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
- What it does not
- How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
- Exactly what was read
- Version 0.3.10, the file with digest sha512-EKIc+2mFs9MjpOhWy0H+4oQIvjvHp6uxPA3b36fKh+1Rui1mMC9iTxFbb9Cr42Cewg8fa39lNAMLok3Q/u1EQQ==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
- Authentication
- Runs locally. No hosted endpoint is listed for this package. You run it on your own machine, so there is no endpoint of ours to authenticate against.
Adding it
Run it with:
npx -y tokviz@0.3.10Pinned to 0.3.10, which is the version the findings above were found in. Drop the version to take whatever is newest, and the report on this page stops describing what you installed.

It renders the current rung (static scanned) and links back here, where what that does and does not establish is one click away. It updates itself as the evidence deepens.
