Documentation Overview

OpenChainBench

Open, reproducible benchmarks for crypto infrastructure. Aggregators, bridges, RPCs, oracles, price feeds, prediction markets, perp DEXes, cross-chain messaging. Same metric, same conditions, every provider. Live at openchainbench.com.

OpenChainBench publishes one benchmark at a time, each shipping with the harness that produces its data. The goal is to make performance an observable property of crypto infra, measured in the open, by anyone who wants to add a provider or a metric.

Community-run, MIT-licensed harnesses + CC-BY-4.0 data, PRs from any party including the providers we benchmark.

At a glance

94 live benchmark specs across 8 categories (RPCs, Trading, Aggregators, Bridges, Blockchains, RWA, Explorers, NFT APIs)
50 self-contained Go harnesses, each shipping a /metrics Prometheus endpoint
32 curated question/answer pages · 23 "alternatives to X" landing pages
26 machine-readable API routes (citation, badges, MCP, feeds, per-format quotes)
One shared Prometheus, one materialization worker, CDN-fastpath snapshot store: cold reads in < 100 ms edge, no origin fan-out on hot paths

Quickstart

bash

pnpm install
pnpm dev              # site at http://localhost:3000
pnpm validate         # bench spec Zod schema check (run before opening a PR)
pnpm typecheck        # tsc --noEmit

Adding a benchmark, writing a harness, or fixing a number: see CONTRIBUTING.md + the visual walkthrough at /contribute.

Machine-readable surfaces

Every benchmark is licensed CC-BY-4.0 and exposed through endpoints designed for citation by journalists, devs, and AI agents:

Endpoint	Audience	What it returns
`/llms.txt` · `/llms-full.txt`	LLM crawlers	Plain-text index (short) + full Markdown context (long) per the llmstxt.org convention.
`/api/citable`	Devs, agents	Flat JSON: every benchmark with current value, leader, headline sentence, citation URL, OG image URL.
`/api/stat/<slug>`	Devs, agents	Single benchmark: full rankings, sparkline (24h), methodology, paste-ready quote, attribution URL.
`/api/cite/<slug>/<format>`	Zotero, Mendeley, Perplexity	Citation in `bibtex`, `apa`, `ris`, or `txt` with the correct MIME type.
`/api/openapi.json`	LangChain, custom GPTs, generic clients	OpenAPI 3.1 schema describing every endpoint.
`/api/mcp/mcp`	MCP clients (Claude Desktop, Cursor, ChatGPT tools)	MCP server: `list_benchmarks`, `get_benchmark`, `query_prom` tools + `openchainbench://benchmark/{slug}` resource.
`/api/freshness`	Live UI, dashboards	`{slug → asOf ms}` map. Edge-cached 5 s.
`/api/llm-context`	LLM system prompts	Every benchmark with rankings + methodology in one Markdown blob.
`/benchmarks/<slug>/opengraph-image`	X, LinkedIn, Slack, iMessage	1200×630 PNG with current value + leader + sparkline. Auto-served on link unfurl.
`/benchmarks/<slug>/share-card?template=...`	Manual export	5 templates (ranking / snapshot / headline / compare / leaderboard), `?theme=dark` supported.
`/api/badge/<bench>/<provider>`	Provider sites, READMEs	360×36 embeddable SVG with the provider's rank + headline figure.
`/rss.xml` · `/feed.json`	Feed readers, agent tooling	RSS 2.0 + JSON Feed 1.1 mirrors, one entry per live bench, updated on release.
`/sitemap.xml` · `/robots.ts`	Crawlers	Every AI crawler (GPTBot, ClaudeBot, PerplexityBot, Google-Extended, CCBot, …) explicitly allowed.

Structured data on every bench page: Dataset + StatisticalReport + Observation + TechArticle + FAQPage + BreadcrumbList JSON-LD, plus a schema.org Dataset microdata graph layered on the visible "At a glance" infobox.

Journalist citation format (what /api/stat/<slug>.headlineSentence emits):

Code

"Mobula leads head lag at 0.8s (p50, 24h) on Fastest onchain data provider.
Source: OpenChainBench (https://openchainbench.com/benchmarks/aggregator-head-lag)"
