Every year, the SaaS graveyard gets a little bigger. Tools you relied on yesterday can vanish tomorrow, taking your workflows, your data, and your momentum with them. In 2025, the trend accelerated. Funding dried up, acquisitions gutted beloved products, and free tiers disappeared without warning.

If you're building a business on top of third-party software, this is the risk nobody talks about at sign-up. Here are 12 tools that shut down, got acquired, or sunset critical features in 2025, and what you can learn from each one.

The graveyard is growing

The SaaS boom of 2020-2022 created thousands of new tools, many of them funded by cheap venture capital. When interest rates climbed and funding dried up, the reckoning began. 2025 was the year the bill came due. More tools shut down or pivoted beyond recognition than in any year prior. And the pattern is clear: if a tool can't reach profitability on its own, it won't survive the next downturn.

12 tools that died or changed forever in 2025

1. Atom Editor (GitHub)

What happened: GitHub officially archived Atom in late 2024 and pulled all remaining support in early 2025. The once-beloved code editor that pioneered Electron couldn't compete with VS Code, which was built by the same parent company, Microsoft.

What replaced it: VS Code, Zed, or Sublime Text. Most developers had already migrated years earlier.

2. Heroku Free Tier

What happened: Salesforce eliminated Heroku's free tier in late 2022, but the full impact rippled through 2025 as legacy free-tier apps were finally purged and the platform continued raising prices. Thousands of hobby projects, bootcamp demos, and small MVPs went offline.

What replaced it: Railway, Render, and Fly.io absorbed most of the displaced developers. Vercel and Netlify picked up the static site crowd.

3. Google Domains

What happened: Google sold its entire domain registrar business to Squarespace in 2023. Through 2025, the migration completed and Google Domains ceased to exist entirely. Millions of domains transferred whether their owners liked it or not.

What replaced it: Cloudflare Registrar became the go-to for developers who wanted no-markup pricing and tight CDN integration. Namecheap and Porkbun also gained share.

4. Deta (Cloud Platform)

What happened: Deta, the free-forever cloud platform for Python and Node.js apps, shut down its Deta Cloud service in 2025 after pivoting entirely to Deta Space, which itself struggled to gain traction. Users were given limited time to export data.

What replaced it: Supabase, PlanetScale (before its own free tier changes), and self-hosted solutions on Railway.

5. Coda's Free Team Features

What happened: Coda aggressively restricted its free tier throughout 2025, locking collaboration features, automation runs, and integrations behind paid plans. What was once a generous Notion alternative became nearly unusable without paying.

What replaced it: Notion maintained its free tier for individuals. Many small teams moved to self-hosted options like AppFlowy or simply went back to spreadsheets.

6. Gitpod (Cloud Workspaces)

What happened: Gitpod drastically scaled back its cloud-hosted development environments in 2025, shifting focus to enterprise self-hosted deployments. The generous free tier that attracted open-source contributors vanished.

What replaced it: GitHub Codespaces became the default for most developers. Devbox and local dev containers picked up the rest.

7. Mailgun Starter Plan

What happened: After years of slow degradation under Sinch ownership, Mailgun eliminated its flex/starter plan in 2025 and raised minimum pricing. The once-developer-favourite email API became cost-prohibitive for early-stage projects.

What replaced it: Resend, Postmark, and Amazon SES. Resend in particular captured the developer audience that Mailgun abandoned.

8. Notion AI (Standalone)

What happened: Not a shutdown, but a significant shift. Notion bundled AI into all paid plans in 2025, effectively killing the standalone AI add-on pricing. Users who only wanted the AI features without the full workspace found themselves paying more.

What replaced it: Claude, ChatGPT, and other standalone AI tools for those who wanted AI without a full productivity suite.

9. Skiff (Privacy Suite)

What happened: Skiff, the privacy-focused email and document suite, was acquired by Notion in early 2024. By mid-2025, all Skiff products were fully shut down. Users who chose Skiff specifically for its end-to-end encryption were forced to migrate to less private alternatives.

What replaced it: Proton Mail and Proton Drive for privacy-focused users. Tuta (formerly Tutanota) also gained users from the migration.

10. Netlify's Generous Free Tier

What happened: Netlify progressively tightened its free tier bandwidth limits and build minutes throughout 2025. What used to be 100GB bandwidth dropped, and serverless function invocations got capped aggressively. Not a shutdown, but a death by a thousand cuts for free-tier users.

What replaced it: Vercel and Cloudflare Pages absorbed developers who needed static hosting with serverless capabilities.

11. Stormkit (Deployment Platform)

What happened: Stormkit, a smaller deployment and hosting platform for JavaScript apps, quietly shut down in 2025 after failing to raise a new round. Users received a 30-day notice to migrate.

What replaced it: Vercel, Netlify, and Cloudflare Pages. The deployment platform market had simply become too competitive for smaller players.

12. PlanetScale Free Tier

What happened: PlanetScale, the serverless MySQL platform beloved by developers, eliminated its free tier in 2025. The Hobby plan that gave you a free database with branching disappeared, forcing thousands of side projects to migrate or start paying.

What replaced it: Supabase (Postgres), Turso (libSQL), and Neon (Postgres) became the go-to free database options. Many developers also reconsidered SQLite for simpler projects.

The warning signs your tool might be next

These shutdowns rarely happen overnight. There are almost always warning signs if you know what to look for:

  • Funding dries up. If a tool hasn't raised in 18+ months and isn't profitable, the clock is ticking. Check Crunchbase before you build a dependency.
  • Team layoffs. When a company lays off 30% of its staff, that's not "streamlining." That's survival mode. Your favourite feature is probably on the chopping block.
  • Acquisition rumours. Acquisitions kill more tools than bankruptcy does. When a bigger company buys your tool, they're buying the team, not the product. Give it 12-18 months before the sunset notice arrives.
  • Pricing changes. Sudden, aggressive pricing increases are a sign that the company is desperately trying to reach profitability. Free tier restrictions usually come first, followed by across-the-board price hikes.
  • Slowing updates. If the changelog goes quiet for months and the community forums fill with unanswered questions, the team has mentally moved on. You should too.

How to protect yourself from software shutdown risk

Own your data

Export everything, regularly. Don't wait for a shutdown notice to discover your tool doesn't have a proper export function. Set a quarterly reminder to download your data from every critical tool in your stack. If a tool doesn't offer a full data export, that's a red flag on its own.

Avoid vendor lock-in

The more proprietary a tool's format, the harder it is to leave. Choose tools that use open standards where possible. Store documents in Markdown, not proprietary formats. Use Postgres instead of a custom database. Prefer standard APIs over custom SDKs. The switching cost should be measured in hours, not weeks.

Have a backup plan for critical tools

For every tool in your stack that would cripple your business if it disappeared, you should have an answer to: "What do we switch to, and how fast?" You don't need a full migration plan, but you need to know the alternative exists and that your data is portable enough to make the move.

Diversify your stack's risk

Don't build your entire business on one ecosystem. If everything runs through one company's products, you're one acquisition away from starting over. Spread your dependencies across multiple vendors with strong track records and sustainable business models.
