Self-host the SaaS you use.

ChatGPT is OpenAI's consumer chatbot. People want open-source alternatives for privacy, offline use, custom fine-tuning, and to avoid the $20/mo subscription.

Notion is the leading "all-in-one workspace" — docs, wikis, databases, projects. People want OSS alternatives for self-hosting, privacy, no vendor lock-in, and to escape the $10/user/month team plans.

Figma is the dominant collaborative design tool. After Adobe's attempted acquisition, many teams want OSS alternatives for self-hosting, file portability, and to avoid future pricing changes.

Canva is the dominant easy-design tool for non-designers (social posts, presentations, marketing materials). OSS alternatives are scarce but exist.

Airtable popularized spreadsheet-database hybrids. Open-source alternatives exist for self-hosting, removing per-user pricing, and avoiding the workflow lock-in.

Google Analytics is free but invasive (tracks users with cookies, requires GDPR cookie banner, slows your site). OSS alternatives are privacy-first, GDPR-safe, and faster.

Slack is the team chat default. OSS alternatives matter for self-hosting (privacy/compliance), avoiding per-user pricing, and keeping data on-prem in regulated industries.

Zapier popularized "if-this-then-that" automation between SaaS apps. OSS alternatives let you self-host, avoid per-run pricing, and use unlimited steps.

Discord dominates community chat but locks you in. OSS alternatives matter for community ownership, no ads/data harvesting, and self-hosting for privacy-sensitive groups.

GitHub is owned by Microsoft. Open-source alternatives exist for self-hosting your code (sovereignty, privacy) and to avoid MS lock-in.

Typeform makes beautiful conversational forms. OSS alternatives let you self-host (no per-response pricing), keep response data private, and brand fully.

Dropbox/Google Drive/OneDrive all dominate file sync. OSS alternatives let you keep your files on your own servers — critical for privacy, EU GDPR, sovereignty.

Mailchimp is the popular email marketing tool. OSS alternatives let you self-host and pay only for sending infrastructure (e.g. SES at ~$0.10 per 1000 emails) instead of per-subscriber.

Calendly is the dominant scheduling tool. Open-source alternatives let you self-host, brand fully, and skip per-user pricing.
