APIGraveyard: Deprecated & Sunset API Migration Risk Tracker for SaaS Builders

The Problem

A recurring nightmare documented on HN and r/programming is that third-party APIs — Stripe, Twilio, Mailgun, Plaid, and dozens of others — deprecate endpoints with 6–12 months notice, and solo developers only discover this when a production feature silently breaks or a deprecation email gets buried in a shared inbox. APIGraveyard monitors the APIs your app depends on, tracks their official deprecation announcements and changelog feeds, and generates a prioritized migration task list with estimated effort — before the deadline hits.

Target Audience

Solo developers and small engineering teams running production SaaS apps with 5+ third-party API integrations

Monetization Angle

$19/mo for up to 10 APIs monitored; $49/mo for unlimited APIs + Slack/email alerts + team seats

Recommended Tech Stack

Why Now

The explosion of API-first SaaS means the average indie app now integrates 8–15 third-party services, and providers are accelerating versioning cycles — Stripe alone has had 3 major API version deprecations in 4 years.

MVP Scope

Let a developer paste a list of APIs they use, auto-subscribe to their official deprecation RSS/changelog feeds, and send a weekly digest email of any announced sunsets with a deadline countdown.

AI Angle

AI parses unstructured changelog blog posts and release notes to extract deprecation signals and map them to specific endpoints the user's codebase actually calls.

Primary Risk

Many API providers don't publish machine-readable deprecation feeds, requiring fragile scraping — the biggest technical risk is coverage breadth before it feels useful.

Validation Checklist

• Post on HN: 'Ask HN: How do you track when third-party APIs you depend on get deprecated?' and catalog the pain in responses
• Search GitHub for issues labeled 'breaking change' or 'api deprecation' across popular indie SaaS repos to quantify how often this causes production incidents
• Build a static landing page listing the 20 most commonly deprecated APIs of the past 2 years and measure organic search traffic from 'API deprecation tracker' queries
• Reach out to 10 solo developers on r/webdev who have publicly complained about surprise API breaking changes and offer free early access in exchange for a 15-minute call

Who Would Pay For This

Likely buyers are engineering teams, platform leads, developer-experience teams, and technical founders. Start with Solo developers and small engineering teams running production SaaS apps with 5+ third-party API integrations and look for teams already spending time or money on this workflow.

First 10 Users

Find the first 10 users by searching for recent complaints around "developer tools API" in Hacker News, developer communities, GitHub issues, and niche Slack or Discord groups. Offer a concierge version first: manually solve the workflow for a few users, then automate only the repeated steps.
