Feature Flags
Feature Flags tools are for rolling out features safely — the kind of work every indie hacker eventually hits and would rather not build from scratch. 7 tools are listed here, each picked and written up individually rather than pulled from an affiliate feed. ConfigCat is usually the first one people try: fixed, transparent pricing and a genuinely usable free tier — refreshing in a category full of per-seat pricing games. DevCycle takes a different angle — built OpenFeature-native from day one specifically so you're not stuck with them if you change your mind later. And Flagsmith is worth a look too: open source flags you can self-host for free and actually own, instead of trusting a vendor's uptime page. Every listing below includes the actual tradeoff, not marketing copy, so you can pick based on what you're building instead of what ranks highest in a sponsored roundup elsewhere.

Built OpenFeature-native from day one specifically so you're not stuck with them if you change your mind later.
Open source flags you can self-host for free and actually own, instead of trusting a vendor's uptime page.
Flags and A/B tests that read straight from your own warehouse, so the stats aren't locked inside someone else's black box.
The category-defining flag platform — mature and powerful, but you'll feel the enterprise pricing before you feel the need for it.
Flags and real experiment statistics in one dashboard, which is why OpenAI and Notion run releases through it instead of a spreadsheet.
The biggest open source flagging project by a wide margin — pay for managed hosting or run it yourself for nothing.
