1. dif.sh
Tagline: Markdown feature flags your coding agent installs for you
Description: Open source feature flags. Every flag is a markdown file that lives with the code it controls: what it does, why it exists, and what you decided, reviewed in a PR like any other change. Your coding agent installs Dif in one command, no account, and reads the context file so it knows what’s live and what was already tried. A/B tests wait in the same files until you have traffic. Send events to your own analytics, or let Dif Cloud read the results and write the decision into the file.

2. Reflexio
Tagline: Behavioral learning that makes AI agents better over time
Description: Reflexio makes AI agents better with every interaction. When users correct an agent, a path fails, or something works particularly well, Reflexio turns that experience into behavior the agent can reuse next time. Instead of leaving valuable lessons buried in logs, your agent continuously learns what to repeat and what to avoid — with every learning visible, testable, and reversible. Reduce task failure rate by more than 30%, while saving tokens by more than 60%.

3. Ponytail
Tagline: Make new code the last resort
Description: Ponytail is a plugin that makes coding agents write the least code that works. Before adding anything, it checks whether the change is needed, already exists, or can use the stdlib or a native API. Same behavior, fewer lines to own.

4. Hyperprobe
Tagline: Lets your AI agents debug production without redeploying
Description: HyperProbe is how backend teams debug production issues they can’t reproduce locally. Instead of adding a log line and waiting on a deploy, we let Claude Code, Codex, or Cursor drop read-only probes into a running service and capture the variable state that was never recorded. From there your agent debugs like it has a local repro, closing the bug in one sitting.

5. at8pm
Tagline: Your honest journal
Description: Every entry you write today locks at the time that you configured — 8pm by default. Once it locks, that’s it: no editing, no rewriting history, no quietly polishing what you actually felt in the moment. Just an honest, raw, and unfiltered record of your day. Entries sync across your devices with your own private iCloud and never with a first/third-party server. When typing is not enough, record a squope (square video) or an audio note. at8pm is free to download (up to 2 entries per day).
