02 — How it works
Paste your provider admin keys once. Encrypted at rest with AES-256-GCM. Never logged, never displayed.
Usage syncs every hour. See spend by day, model, and provider on a dashboard that doesn't hurt your eyes.
Budget alerts fire before bill shock. The optimization engine flags wasted spend and cheaper model alternatives.
Monthly limit crossed at $487 / $450.
03 — Features
What others charge $20/seat for, Obol does for $5 flat. No per-seat pricing. No usage tiers. No surprises.
OpenAI, Anthropic, Google, OpenRouter, Mistral, Groq, xAI, DeepSeek, Cohere. No tab-switching between provider consoles.
See exactly which model is eating your budget — by spend, requests, tokens, and cache hits. Not just totals.
Automatically spots wasteful model usage and suggests cheaper alternatives with the same capabilities. Pays for itself on day one.
Exponentially smoothed projection with day-of-week adjustment. Know your bill before the bill — not after.
See your prompt-cache hit rate per model, savings already earned, and money still on the table. No other tool shows this.
MAD catches sudden spikes. CUSUM catches the slow $2/day creep that basic threshold alerts miss entirely.
Email and Slack notifications when spend crosses your threshold — daily, weekly, or monthly. No more bill shock.
Pull your usage data for accounting, compliance, or your own dashboards. Your data, no lock-in.
AES-256-GCM encryption on every API key. Never logged. Never displayed. PBKDF2 passwords. No tracking cookies.

05.5 — Personality
The mood meter at the top of your overview is a running commentary on your spend. Three flavours: professional for the standup, casual for most days, unhinged when you need a wake-up call.

07 — Questions
You connect your provider API keys (admin keys for OpenAI and Anthropic, management key for OpenRouter's activity API). We call each provider's usage endpoint hourly, with idempotent upserts so re-runs never double-count. For Google AI — which has no public usage API — upload a CSV from Google AI Studio.
Simple exponential smoothing over your month-to-date daily spend gives us a recency-weighted daily rate — early-month outliers stop dominating the projection. Once you have 14+ days of history, day-of-week multipliers kick in so Wednesday doesn't get treated like Saturday. The card shows a confidence tier (low / moderate / high) so you know when to trust the number.
Two detectors, not one. A Modified Z-score using median + MAD catches single-day spikes and is robust against the outlier-masking effect that plain z-score has on bursty spend. Separately, CUSUM watches the 14-day window for gradual drift — the $2/day creep that point-spike detectors never see. Both run per-provider, so a +$30 OpenAI spike offset by -$20 Anthropic still fires.
Often yes, and Obol shows you exactly how much. The cache dashboard tracks your prompt-cache hit rate per model, the savings you've already earned from hits, and the additional savings still on the table if you improved your hit rate to 100%. Models that don't support caching are excluded — no noise.
Yes. All keys are encrypted at rest with AES-256-GCM. We never log or display plaintext keys.
Nine providers: OpenAI, Anthropic, Google AI, and OpenRouter for dashboard sync + proxy. Mistral, Groq, xAI (Grok), DeepSeek, and Cohere for proxy-only with real-time cost tracking. The LLM proxy works with any OpenAI-compatible API.
Yes. Pro is monthly — cancel from Settings → Billing. You keep Pro access until the end of the current billing period.
Most LLM observability tools require an SDK wrapper, a proxy library, or a framework integration. Obol works by syncing directly with provider billing APIs — no code changes for OpenAI, Anthropic, or OpenRouter. When you do use the proxy, it's a one-line base URL swap, not an SDK. Pricing is $5/month flat, not per-seat or per-event. And Obol tracks cache savings and forecasts your month-end bill — features most tools don't offer at all.
Fast, global, and free to start. We run on Workers + D1 + KV, which lets us keep pricing at $5/mo while serving from 300+ edge locations worldwide.
