- 💰 Revenue: Modest — $1K - $7K/mo · INDIE tier · medium confidence, trajectory unclear.
- ⭐ Quality: 4.49★ across 88 reviews — weak — significant quality concerns.

- 📈 Growth: ⚠ last update 3649d ago — possibly dormant.
- ⚠️ Risk: Elevated — bug mentions above category norm, dormant (3649d since update).
🎯 For competitors: Vulnerable. Quality drift + slow updates create a clear opening for a fresh competitor with active dev cadence.
💵 For acquirers: Estimated asking range 12-22× monthly = $37K-$68K. Portfolio play ($31K/mo combined) commands premium. Discount applied for operational risk..
