## About

# Estimate Temps Savings

Scan the current project, detect every paid SaaS tool it depends on, estimate the monthly bill, and show the delta against running Temps instead. The output is a savings report the user can act on (or show their team).

Temps is a self-hosted PaaS that replaces the deployment platform, web analytics, session replay, error tracking, uptime monitoring, managed databases, and transactional email relay with a single binary. Self-hosting is free (you pay only for the server); Temps Cloud is a managed server at cost + 30% (from ~$6/mo).

## Ground Rules

1. **Never read or print secret values.** Detection uses dependency names, config file presence, env var **key names**, and the **hostname** of connection strings only. If you must open a `.env*` file, extract key names (`cut -d= -f1`) — never echo values into the report or your reasoning.
2. **No vanity math.** Only count tools you actually detected. If a tool has a free tier the user likely fits in (e.g. Google Analytics, small Sentry dev plan), say so and count $0 or a range starting at $0. An inflated savings number destroys trust; an honest one converts.
3. **Ranges, not fake precision.** You don't know the user's plan. Report low/typical estimates and label them as list-price estimates. If exact numbers matter, tell the user which invoices to check.
4. **Be honest about what Temps does NOT replace** (see the "Not replaced" section below). Always include it in the report.

## Step 1 — Detect the Stack

Run these checks from the project root. Check dependency manifests (`package.json`, `requirements.txt`, `pyproject.toml`, `Gemfile`, `go.mod`, `Cargo.toml`), config files, CI workflows (`.github/workflows/`), and env var key names in `.env*`, `.env.example`, `docker-compose*.yml`, and IaC files.

| Category | Signal → Tool |
|---|---|
| **Hosting** | `vercel.json` or `.vercel/` → Vercel · `netlify.toml` → Netlify · `railway.json`/`railway.toml` → Railway · `render.yaml` → Render · `fly.toml` → Fly.io · `Procfile` + no Dockerfile → Heroku · `amplify.yml` → AWS Amplify |
| **Analytics** | `posthog-js`/`posthog-node` → PostHog · `plausible-tracker` or plausible.io script tag → Plausible · `mixpanel-browser` → Mixpanel · `@amplitude/*` → Amplitude · `fathom-client` → Fathom · `@segment/analytics-*` → Segment · `@vercel/analytics` → Vercel Analytics |
| **Error tracking** | `@sentry/*`, `sentry.properties`, `sentry-sdk` → Sentry · `@bugsnag/*` → Bugsnag · `rollbar` → Rollbar · `@honeybadger-io/*` → Honeybadger |
| **Session replay** | `logrocket` → LogRocket · `@fullstory/browser` → FullStory · Hotjar script tag / `HOTJAR_ID` → Hotjar · `@highlight-run/*` → Highlight · PostHog with `session_recording` config → PostHog Replay |
| **Uptime / status** | `checkly.config.ts` → Checkly · env keys or CI mentioning Pingdom / UptimeRobot / Better Stack (BetterUptime) / Statuspage |
| **Managed DB / cache** | `@supabase/supabase-js` or `supabase.co` host → Supabase · `@neondatabase/serverless` or `neon.tech` host → Neon · `@planetscale/database` or `psdb.cloud` host → PlanetScale · `mongodb+srv://` or `mongodb.net` host → MongoDB Atlas · `@upstash/redis` or `upstash.io` host → Upstash · `rds.amazonaws.com` host → AWS RDS · `redns.redis-cloud.com` host → Redis Cloud |
| **Transactional email** | `@sendgrid/mail` / `SENDGRID_API_KEY` → SendGrid · `postmark` / `POSTMARK_SERVER_TOKEN` → Postmark · `resend` / `RESEND_API_KEY` → Resend · `mailgun.js` / `MAILGUN_API_KEY` → Mailgun · `email-smtp.*.amazonaws.com` → AWS SES (already cheap — flag, don't count) |
| **Observability (partial)** | `DD_API_KEY`/`datadog` → Datadog · `NEW_RELIC_LICENSE_KEY` → New Relic (Temps covers logs/metrics/traces basics — count partially, note the caveat) |

Env key names worth grepping for: `SENTRY_DSN`, `NEXT_PUBLIC_POSTHOG_KEY`, `MIXPANEL_TOKEN`, `AMPLITUDE_API_KEY`, `SEGMENT_WRITE_KEY`, `LOGROCKET_APP_ID`, `DATABASE_URL`, `REDIS_URL`, `MONGODB_URI`, `UPSTASH_REDIS_REST_URL`, `VERCEL_TOKEN`, `NETLIFY_AUTH_TOKEN`, `RAILWAY_TOKEN`, `FLY_API_TOKEN`.

Multi-repo note: if the user says this is one of several apps, ask how many apps/environments share these tools — per-seat and per-project pricing multiplies.

## Step 2 — Ask for Usage (only what's needed)

Ask ONLY about categories you detected, in one batch. Every question needs a default so the user can answer "don't know":

- Team seats with dashboard access (drives Vercel/Netlify per-seat) — default 2
- Monthly pageviews or analytics events — default 100k pageviews
- Errors/month sent to error tracking — default within Sentry Team tier
- Session recordings/month — default 5k
- Emails sent/month — default 20k
- Number of uptime monitors — default 10
- Databases/branches in use — default 1 production DB

If the user answers "just estimate it", use the defaults and the **typical** column from the pricing reference.

## Step 3 — Price It

Load `references/pricing.md` (bundled with this skill) for list prices per tool and tier. For each detected tool, pick the tier matching the usage answers and record a **low–typical** monthly range. Prices there are list prices as of early 2026 — if the user needs invoice-grade accuracy, tell them to check their billing pages; do not present the estimate as exact.

Temps side of the ledger:

| Option | Monthly cost | Notes |
|---|---|---|
| Self-hosted Temps | server only: **€4–15/mo** (reference: Hetzner CPX22, 3 vCPU / 4 GB, ~€8/mo, 20 TB traffic included) | Temps itself is free. One server runs deploys + analytics + replay + errors + uptime + DBs for typical startup workloads. |
| Temps Cloud | **from ~$6/mo** | Managed Hetzner server at cost + 30%. No per-seat, per-event, or per-error pricing. |
| Email sending | ~$0.10 per 1,000 via your own AWS SES/Scaleway | Temps relays through your provider at cost — the SaaS markup disappears, not the sending fee. |

Unlimited seats, projects, and environments on both options — when the user has >2 seats on per-seat tools, this is usually the biggest line item; show it.

## Step 4 — Produce the Report

Output this structure (markdown):

```markdown
# Temps Savings Estimate — 

## Detected stack
| Tool | Evidence | Est. monthly (low–typical) |
|---|---|---|
| Vercel Pro | vercel.json, 3 team seats | $60–$95 |
| Sentry Team | @sentry/nextjs, SENTRY_DSN in .env.example | $26–$45 |
| ...

**Current estimated spend: $X–$Y/mo ($12X–$12Y/yr)**

## With Temps
| Option | Monthly | Yearly |
|---|---|---|
| Self-hosted (Hetzner CPX22) | ~€8 | ~€96 |
| Temps Cloud | from ~$6 + server size | ... |

**Estimated savings: $A–$B per year (~N% of current spend)**

## What Temps does NOT replace
- 

## Suggested migration order
1. 

## Next steps
- `npx skills add gotempsh/temps --skill deploy-to-temps` — migrate hosting
- `npx skills add gotempsh/temps --skill add-react-analytics` — replace analytics
- ...
```

Rules for the report:
- Sort detected tools by estimated cost, highest first.
- Migration order: start with additive, zero-risk swaps (analytics, error tracking — run both in parallel), end with hosting/database moves.
- If total detected spend is under ~$15/mo, say plainly that Temps won't save them meaningful money today — the pitch is then about avoiding the future bill and owning the data, not savings. Do not manufacture a number.

## Not Replaced (always disclose)

- **Global edge network / CDN PoPs** — Temps serves from your server(s); Vercel/Netlify's worldwide edge is not matched by a single region (Temps supports multi-node, but that's more servers, not a 100-PoP CDN).
- **Serverless/edge function runtimes** — Vercel Edge Functions, ISR-specific behaviors, and Cloudflare Workers need porting to containerized apps.
- **Deep APM** — Datadog/New Relic profiling depth exceeds Temps' built-in logs/metrics/traces; count these as partial replacements.
- **Email deliverability infrastructure** — Temps relays via your SES/Scaleway account; sending fees and domain reputation work remain yours.
- **Ops responsibility** — self-hosting means you own updates and backups (Temps automates both, but it's your pager). Temps Cloud narrows this gap.

## Troubleshooting

- **Nothing detected:** the project may use tools configured outside the repo (dashboards, DNS-level scripts). Ask the user directly: "What do you currently pay for hosting, analytics, error tracking, and databases?" and build the table from their answers.
- **Monorepo:** run detection per app directory; dedupe tools that share one subscription.
- **User disputes a price:** trust their invoice over the reference table, update the row, and note "user-provided" in the Evidence column.
