SurrealDB is positioned around relational, document and graph data models. That breadth can be useful, but it does not settle whether the database fits your workload or whether its hosted-service licensing works for your plans. The listed starting price is $15, with a free plan. Our shortlist focuses on clearer fits: document-first apps, Postgres projects, AI-agent memory and analytics. Pick the workload first, then compare cost and the capabilities you would give up.
01Why people leave SurrealDB
The Postgres case is not obvious
One Reddit commenter asks why to use SurrealDB over Postgres. That is a comparison question, not proof of widespread churn, but it is worth answering before switching.
Hosted-service licensing needs review
In a Reddit launch thread, a developer described a license restriction on providing a paid hosted database platform. Check the current license against your business model.
Early architecture drew questions
A developer in a Reddit thread described distributed mode as running on TiKV and an in-house key-value store as planned. Treat that as an early account, not current documentation.
02The alternatives, ranked by fit
- Document-first applications
MongoDBMongoDBChoose MongoDB if your application is document-first and you want to stop paying for breadth you do not need. Its listed fit also includes teams choosing between cloud and self-managed use. The pricing summary lists a free plan and a starting price of $8. This is a better match for document-shaped application data than choosing SurrealDB solely because it supports several models.
Trade-off: You are choosing a document-first database, not SurrealDB’s stated mix of relational, document and graph models.

$8/mofree plan - Relational data with JSON
PostgreSQLPostgreSQLPostgreSQL is the clearest alternative to evaluate if your data is relational and you still need JSON. It is listed as open source with a free plan, and its stated tradeoff is that teams need to plan schemas. A Reddit commenter’s direct question—why use SurrealDB over Postgres?—makes this a sensible baseline before adopting a broader database.
Trade-off: Schema planning is part of the deal; its listed fit is relational data with JSON, not an all-model consolidation pitch.
8.0/10from
Freefree plan - Postgres with branching
NeonNeonNeon fits teams already choosing Postgres, especially projects that need database branching or have variable load. That gives you a more focused Postgres route than switching to SurrealDB for multiple data models. The listing includes a free plan and a $15 starting price, but calls out usage-based pricing as something to budget carefully.
Trade-off: Usage-based pricing needs close budgeting, and the listed fit is specifically a Postgres backend.
7.0/10from
$15/mofree plan - Documents and vector search
MongoDB AtlasMongoDB AtlasMongoDB Atlas is worth comparing when the project is document-based and also needs vector search, or when developers want to explore on a free tier. Its listed starting price is $8 with a free plan. Compared with choosing SurrealDB for broad model coverage, Atlas gives teams a more specific document-and-search reason to switch.
Trade-off: Its listed use case is document apps and vector search, not broad data-model consolidation.
7.3/10from
$8/mofree plan - AI agent memory
RedisRedisRedis is a more targeted option if your reason for considering SurrealDB is AI-agent memory, caching or streaming. Those are the listed Redis use cases, and the pricing summary shows a free plan with a $5 starting price. Compare it for those needs rather than treating it as a like-for-like replacement for every database workload.
Trade-off: Redis Pro has a $200 monthly minimum, which changes the cost calculation.
7.4/10from
$5/mofree plan - Real-time analytics
ClickHouseClickHouseClickHouse is the better fit to evaluate when the main workload is real-time analytics or SQL over large datasets. The listing notes local and cloud options, with no starting price published. Its stated caution is practical: the engineering work and variable cloud bill need to fit your team before you move an analytics workload.
Trade-off: The listing warns about engineering demands and a variable cloud bill; no starting price is published.
7.8/10from
Custom - Local SQL analytics
DuckDBDuckDBDuckDB suits SQL-based local data wrangling, including work with CSV or Parquet files, when you want a free analytical database. The listing gives no starting price and identifies a free plan. It is a narrower choice than SurrealDB: evaluate it for analytics, and verify concurrency and support details before relying on it.
Trade-off: Concurrency and support details need verification; its listed focus is analytical work.

Questions people ask
What is the best SurrealDB alternative for relational data with JSON?
PostgreSQL is the most direct option in this shortlist for relational data with JSON. It is listed as open source with a free plan, but its stated tradeoff is that teams need to plan schemas. Neon is another Postgres option if database branching or variable load matters.
Which SurrealDB alternatives have a free plan?
The published pricing summaries list free plans for MongoDB, PostgreSQL, Neon, MongoDB Atlas, Redis and DuckDB. MySQL and Firebird are also listed with free plans, though they are not among this page’s selected picks. Check current plan details before switching; the listed starting prices are not a complete cost estimate.
Which alternative is listed for AI-agent memory?
Redis is the alternative explicitly listed for teams building AI-agent memory, as well as caching and streaming. Its pricing summary lists a free plan and a $5 starting price, but notes that Redis Pro has a $200 monthly minimum. Compare the plan that matches your intended use, not just the entry price.
