Converter Hub
One sidebar for the developer converters you keep googling — JWT, Base64, ObjectId, Snowflake, epoch, JSON ↔ YAML, CSV ↔ JSON, UUID, QR generator + decoder + WiFi, CIDR, plus crypto (MD5/SHA, HMAC, bcrypt, AES-GCM/CBC, RSA-OAEP, X.509 PEM) and Kafka tools (Avro, Debezium, Confluent Schema Registry). All client-side, no network calls, no telemetry.
