Tokenwise is an advanced LLM proxy specifically designed for developers and small teams running AI features in production. It falls under the category of AI observability and optimization, but with a unique focus on LLM cost optimization. The core value is straightforward: provide complete visibility into every API call and enable actionable savings of 20-30% without ever sacrificing output quality. By acting as a drop-in proxy with under 50 milliseconds of overhead, it integrates seamlessly into existing stacks. The product is built for teams whose monthly LLM bills range from $50 to $2,000, offering a straightforward path from black-box spending to one-click fixes.
The concrete problem Tokenwise solves is the hidden waste that inflates LLM bills—waste that is invisible in standard provider dashboards. Most of an LLM bill is composed of prompts loaded but never used, cache misses that re-bill near-identical calls, and expensive models handling tasks a cheaper model could perform equally well. For example, a 2,140-token instruction block sent on requests that never use it, or repeated /faq calls that are billed in full each time. This pain point matters because it silently burns budget and makes it hard to scale AI features profitably. Tokenwise identifies each leak with the dollar figure attached, so teams can stop guessing and start fixing.
The first major feature group is real-time monitoring and visibility. The dashboard updates as fast as traffic flows, displaying cost, latency, errors, and tokens sliced by model, app, or tag. A 14-day spend forecast is pinned at the top, so spend never surprises you. Every call lands with its full metadata, and the system flags waste immediately—oversized prompts, cache misses, and overqualified model usage. This monitor layer works in observe-only mode by default, meaning zero changes to production until the team is ready to optimize. It provides the raw data needed to understand exactly where money goes.
The second major feature group is optimization recommendations with one-click apply. Tokenwise analyzes real traffic against cheaper models, finds cache opportunities, and spots bloated prompts. Each recommendation includes a replay-check against the team's own quality baseline using an LLM-as-judge evaluation engine. For example, swapping Opus to Haiku on /summarize might show a 96% quality match with $842/month savings. Recommendations can be applied directly, run as an A/B experiment on a percentage of traffic, or ignored. Nothing changes silently, and each fix is backed by proof from actual production data.
The third feature group covers protection and safeguards. Cost spikes, latency regressions, and quality dips are caught in real time and routed to email, Slack, or Discord. Budget caps can be set per workspace, and when a threshold is breached, the system can auto-rollback to the last known-good configuration. Quality regression detection using LLM-as-judge scoring ensures that a cost cut never quietly degrades output. This includes a Watchdog mode that automatically reverts model switches if scores drop more than 10%. Together, these features let teams optimize aggressively without fear of breaking their application.

Tokenwise works as a drop-in proxy hosted at the edge on Cloudflare Workers across 300+ POPs. Setup requires changing one line—the base URL—in the existing SDK (OpenAI, Anthropic, Vercel AI SDK, LangChain, or plain fetch/curl). The proxy is observe-only by default, so it logs metadata without altering responses. When optimizations are enabled, the proxy routes calls to the right provider, caches responses when appropriate, and logs every byte for the dashboard. Provider keys are never stored; they are forwarded and dropped from memory. The entire workflow from black box to one-click fixes can be completed in an afternoon.
Concrete use cases show real outcomes. A team spending $680/month on LLM calls reduced their bill by 31% after Tokenwise identified a 38% waste from an oversized system prompt, 21% from cache misses on /faq and /classify calls, and 14% from using Opus where Haiku performed equally well. Another scenario involves a developer whose bill kept doubling every month; after adding Tokenwise they found cache opportunities and trimmed prompts, saving $4,128 across all early teams in a single month. Quality is maintained because each optimization is replay-checked against the team's own golden answers with a current quality match of 96.4%.
Tokenwise is designed for solo makers and small teams shipping LLM apps in production, with monthly bills between $50 and $2,000. It supports native path providers including OpenAI, Anthropic, Google Gemini, xAI Grok, Groq, DeepSeek, Mistral, and OpenRouter. The platform runs on a Cloudflare edge with under 50ms overhead. Pricing starts at $9.50/month for the Indie plan (200,000 requests/month, 10 workspaces) and $39.50/month for the Pro plan (2,000,000 requests, 50 workspaces, LLM-as-judge evals, A/B splits, auto-rollback). Early adopters get 50% off forever with code EARLY50. Tokenwise delivers on its promise: ship faster, spend less, see everything.
Developers and small teams running LLM features in production—apps and SaaS that call OpenAI, Anthropic, Google, or other model APIs through Vercel AI SDK, LangChain, or plain SDK. Ideal for solo makers and startups with monthly LLM bills between $50 and $2,000 who need real-time visibility into spending, one-click optimizations, and quality safeguards. Also suited for teams using multiple providers or managing multiple workspaces and looking to reduce waste without redeploying code.
