Walks you through a pricing model a developer can estimate before signing up: clear metrics, a calculator, spending caps.

## What it does

The skill works through how a developer tool gets priced. Your agent goes metric by metric — API requests, compute time, storage, bandwidth, monthly active users — and notes where each one holds up and where it falls apart. Some metrics get flagged as unusable: opaque “compute units”, compound formulas, multipliers that count retries or health checks. A metric nobody can predict means nobody can estimate the bill.

Next comes the pricing page. The skill lists what belongs there: a unit price, a monthly cost calculator, a tier table, and an FAQ that answers the questions people actually ask, such as what happens after a limit is crossed. Good pages get named, and so do bad patterns — “contact sales” standing in for a number, prices hidden behind signup.

Predictability gets its own section. Usage dashboards with a projected bill, alerts at 75% and 90% of a limit, hard stops, soft stops, burst allowances. The trade-offs are spelled out: a hard cap on a production service means an outage. Invoices matter too — line items per resource beat a single “Usage charges” row. Early on the skill points to a companion one, `/devmarketing-skills/skills/free-tier-strategy`, so the paid plan reads as an extension of the free tier.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add jonathimer/devmarketing-skills --skill usage-based-pricing -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/usage-based-pricing/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/usage-based-pricing/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add jonathimer/devmarketing-skills --skill usage-based-pricing -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/usage-based-pricing/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add jonathimer/devmarketing-skills --skill usage-based-pricing -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/usage-based-pricing/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install jonathimer/devmarketing-skills usage-based-pricing
```

2. **Manually: put the files in place**
- File: `.github/skills/usage-based-pricing/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add jonathimer/devmarketing-skills --skill usage-based-pricing -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/jonathimer/devmarketing-skills --path skills/usage-based-pricing
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/usage-based-pricing/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add jonathimer/devmarketing-skills --skill usage-based-pricing -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/jonathimer/devmarketing-skills/tree/HEAD/skills/usage-based-pricing/SKILL.md

## When to use it
- pick a billing metric developers can estimate in advance
- strip compound formulas and hidden multipliers out of the pricing
- build a monthly cost calculator into the pricing page
- set spending alerts and caps so a bug can't blow up the bill
- rewrite the invoice so every line explains its own amount

## Example prompts
- Go through our API metrics and tell me which ones a developer can predict
- Draft the pricing page: unit price, calculator, tier table and FAQ
- Propose a spending cap setup: hard stop, soft stop and burst allowance

# Usage-Based Pricing

Design pricing models that developers understand, accept, and can predict—without surprise bills or confusing metrics.

## Overview

Developers are uniquely sensitive to pricing. They'll calculate unit economics, compare alternatives, and write blog posts about surprise bills. Usage-based pricing works well for developer tools because it aligns cost with value, but it can also create anxiety about unpredictable costs.

The best developer pricing is predictable, transparent, and obviously fair. Developers should be able to estimate their bill before they commit.

## Before You Start

Review the `/devmarketing-skills/skills/free-tier-strategy` skill to understand how free tiers connect to paid pricing. Your pricing model should feel like a natural extension of the free tier, not a completely different experience.

## Usage Metrics Developers Accept

### Good Metrics: Direct Value Correlation

**API calls/requests**
- Developers understand what triggers a call
- Easy to monitor and predict
- Scales with actual usage
- Example: Stripe charges per transaction, Twilio per message

**Compute time**
- Clear relationship to server costs
- Predictable for consistent workloads
- Fair for variable workloads
- Example: AWS Lambda per GB-second, Vercel build minutes

**Storage**
- Simple to understand
- Easy to predict growth
- Clear cost driver
- Example: S3 per GB stored, databases per GB

**Bandwidth/data transfer**
- Makes sense for CDN and hosting
- Can be surprising if not monitored
- Example: Cloudflare per GB, Vercel bandwidth

**Active users (MAU)**
- Works for auth and user-facing tools
- Aligns with customer's growth
- Example: Auth0, Firebase Auth

### Problematic Metrics

**"Compute units" or proprietary measures**
```
Bad: "1 CU = 0.25 CPU seconds at 1.5GHz equivalent with 256MB memory allocation"
Developers can't estimate usage.
```

**Compound metrics**
```
