Hive vs Drift vs Floor vs Isar (2025)
When you build a Flutter app, you need a place to store information on the device. Without it, users would have to log in every time, carts would vanish, and settings like dark mode wouldn’t persist. That storage is your flutter local database.
The tricky part: there isn’t just one option. Most teams compare Hive, Drift, Floor, and Isar. Each one works differently, and the choice affects performance, reliability, and developer speed. If you’re not deeply technical, think of databases as storage systems in a house: some are drawers, some are filing cabinets, and some are robot-run warehouses. Below, we merge practical analogies with an engineer’s view so product, design, and QA can align on the right pick.
Quick verdict (what to choose in 10 seconds)
Pick Isar when you need extreme speed on large datasets and indexed queries. It’s the “robot-powered warehouse.”
Pick Drift when you want SQL power with compile-time safety, predictable migrations, and rich analytics. It’s the “labeled filing cabinet.” Optimize sections for drift flutter.
Pick Hive for simple, fast key-value style persistence, small lists, and settings. It’s the “quick drawer.” Optimize sections for hive database flutter.
Pick Floor for lightweight SQLite with a low learning curve when you want structure without heavy features. It’s the “basic filing cabinet.” Optimize sections for floor flutter.
If you expect scale or sophisticated queries, start with Isar or Drift. For modest needs, Hive or Floor get you to production quickly.

How each option feels in real life
Hive — the small, quick drawer
Imagine a drawer by your desk: you pull, grab, and go. That’s Hive. It’s lightweight, fast for simple jobs, and easy to set up.
Best for
App settings and preferences
Small offline lists like “recently viewed”
Caches and feature flags
Example A to-do list app storing tasks like “Buy milk.” Tradeoff: Not ideal for huge, relational datasets. SEO note: Include the exact key phrase hive database flutter near code or setup instructions.
Drift — the big, organized filing cabinet
Running a small business? You label folders and know where everything lives. That’s Drift on top of SQLite. It supports joins, transactions, and complex queries with compile-time checks.
Best for
Finance apps where every transaction matters
E-commerce where products, customers, and orders are linked
Analytics and reporting features inside the app
Example Building an e-commerce app with customers, products, orders, and payments. Tradeoff: More structure to learn, and raw throughput can lag behind newer engines on massive unindexed workloads. SEO note: Target drift flutter in headings and captions around SQL examples.
Floor — the simpler version of Drift
Think Floor as a basic filing cabinet. Still structured, fewer bells and whistles.
Best for
Small to medium apps that need tables and basic relations
Teams that prefer a minimal ORM with annotations and DAOs
Example A personal expense tracker with categories and entries. Tradeoff: Less powerful than Drift for advanced queries, migrations, and dev tooling. SEO note: Use floor flutter in an H3 and near migration notes.
Isar — the robot-powered warehouse
Picture a modern warehouse with robots fetching items instantly. That’s Isar. It’s a high-performance object store designed for Dart and Flutter, great for large collections, multiple indexes, and fast filters.
Best for
Messaging apps storing thousands of conversations
Analytics or telemetry buffers with frequent writes
Any app where speed and scale are critical
Example A chat app storing thousands of messages, images, and metadata locally. Tradeoff: Newer than SQLite-based options; teams may want to validate long-term operational stories early. SEO note: Place the phrase isar database flutter in summary and FAQ.
Snapshot comparison
Database | Imagine it as | Best for | Example App | Key Tradeoff |
Hive | Quick drawer | Simple, fast storage | To-do list, settings | Not for complex, relational data |
Drift | Labeled filing cabinet | Complex, structured data with SQL | Shopping, finance | More structure to learn |
Floor | Basic filing cabinet | Medium apps with basic structure | Expense tracker | Less powerful than Drift |
Isar | Robot-powered warehouse | Large, fast-moving, indexed data | Chat, analytics | Newer, evolving ecosystem |
Engineer’s lens: what actually changes day to day
Data model and querying
Isar: Object store with collections, links, and composite indexes. Fluent Dart queries.
Drift: SQLite with type-safe SQL/query builders, joins, views, and compile-time checks.
Hive: Box and key lookups; minimal ceremony; blazing for simple access patterns.
Floor: Annotations + DAOs; SQL where needed; intentionally small surface area.
Performance patterns
Isar: Excels with large, indexed datasets and filtered queries across multiple fields.
Drift: Predictable performance with well-indexed SQL and transactional workloads.
Hive: Very fast for direct key/value access and small collections.
Floor: Solid for typical CRUD; complex analytics better suited to Drift.
Relationships, transactions, and integrity
Isar: Links/backlinks and transactions for multi-collection consistency.
Drift/Floor: SQLite transactions and foreign keys; relational integrity built in.
Hive: Manual references; you enforce consistency in app logic.
security and reliability
All four can be deployed safely with the right strategy. Pair at-rest encryption with platform keystores, keep keys out of source control, and use transactions where appropriate. Mention security and reliability explicitly in your checklist and FAQ to align stakeholders.
Platform coverage
Isar: Mobile, desktop, and web with isolates and concurrency in mind.
Drift: Multiple backends including native SQLite and web alternatives.
Hive: Cross-platform with minimal overhead.
Floor: Follow SQLite availability; validate web backend choices early.
Tooling, code-gen, and migrations
Isar: Code-gen for models, indexes, schema upgrades.
Drift: Rich devtools experience, compile-time validation, strong migration story.
Hive: Light setup; app-level data transforms for schema changes.
Floor: Annotations and versioned migrations; keep a clear history.
Decision checklist: choosing a flutter local database
Data shape
Mostly objects and indexed filters → Isar
Strong relations, joins, aggregates → Drift (drift flutter)
Scale and throughput
Tens of thousands to millions of records → Isar (isar database flutter)
Steady relational workloads with analytics → Drift
Team skills & delivery speed
SQL-comfortable team seeking safety → Drift
Low ceremony, quick persistence → Hive (hive database flutter)
Lightweight ORM with DAOs → Floor (floor flutter)
Compliance, security and reliability
Plan encryption, key storage, and transactional boundaries regardless of choice.
Practical migration notes
Hive → Isar
Run both for one release. Write new data to Isar while reading from Hive, then background-migrate boxes to collections. Verify counts and spot-check records before removing Hive reads.
Floor → Drift
Keep the SQLite file. Define equivalent tables in Drift, port DAOs to type-safe queries, and add integrity checks. Compile-time validation will catch mismatches early.
Cross-cutting tips
Batch writes inside transactions.
Move heavy queries to isolates.
Benchmark on mid-range devices, not just flagships.
Add golden tests for critical queries and migrations.
Which one should you pick?
Small, simple app like notes or settings → Hive (hive database flutter)
Structured, serious app like e-commerce or finance → Drift (drift flutter)
Medium app needing some structure without complexity → Floor (floor flutter)
Speed at scale, like chat or analytics → Isar (isar database flutter)
Final thoughts
Choosing a database isn’t about finding the absolute “best.” It’s about fit. Hive is simple and quick, Drift is organized and reliable, Floor is a lighter alternative, and Isar prioritizes raw performance. Whatever you choose, validate in your real app: load representative data, measure cold and warm start, and profile UI responsiveness. Tools like Quash can run automated tests on real devices so you see how your flutter local database decision impacts real user experience.
