SingleStore is aimed at teams combining transactions and analytics, but that mix may not suit every workload. One Reddit user reported comparable performance to PostgreSQL on their use case, alongside fewer features and compatibility; a SingleStore employee said classic single-machine app workloads may be better served by PostgreSQL. Our shortlist separates analytics, relational, document and specialist options. Listed prices range from free plans to paid starting points, but SingleStore’s price is not listed here. Get compute and storage costs before you plan a switch.

01Why people leave SingleStore

Performance claims may not fit

One Reddit user reported comparable PostgreSQL performance on their workload, with fewer features and less compatibility.

Your workload may be too narrow

A SingleStore employee said classic app workloads on one machine may be better served by PostgreSQL.

Storage openness raises concerns

A Reddit commenter questioned whether SingleStore’s storage format is open, raising a lock-in concern rather than establishing it as fact.

02The alternatives, ranked by fit

  1. Open-source relational database

    PostgreSQL

    Choose PostgreSQL if your priority is an open-source relational database with JSON support, rather than one engine for every workload. It has a free plan, and its listed starting price is n/a. One Reddit user said it performed comparably to SingleStore in their real use case, while noting fewer SingleStore features and compatibility; that is one workload, not a universal comparison.

    Trade-off: You still need to plan your schemas.

  2. Real-time analytics

    ClickHouse

    If analytics over large datasets is the main reason you chose SingleStore, ClickHouse is a more focused alternative. It is listed for real-time analytics, SQL workloads and local or cloud use. One Reddit commenter described a Kafka engine table with an AggregatingMergeTree materialized view as very fast for their query; treat that as an individual report, not a guarantee.

    Trade-off: The listing flags engineering work and a variable cloud bill.

  3. Existing MySQL applications

    MySQL

    MySQL is the practical candidate if you are leaving SingleStore to return to an existing MySQL application or need a free database. Its listing also names embedded product vendors as a fit. The listed starting price is $178.33 despite a free plan being noted, so check what that paid edition includes before you budget for a move.

    Trade-off: Compare alternatives before buying a paid edition.

  4. Document-first applications

    MongoDB

    MongoDB fits teams whose application data is document-first, rather than teams choosing a database simply because their app stores JSON. The listing includes cloud or self-managed deployment and a free plan, with a starting price of $8. Consider it when document workloads are the reason for leaving; it is not listed as a general-purpose HTAP substitute.

    Trade-off: Its listed fit is document-first, not every workload.

  5. Caching and streaming

    Redis

    Redis makes more sense when the workload you want to separate from SingleStore is caching, streaming or AI agent memory. The listing gives it a $5 starting price and a free plan, but its Pro plan has a $200 monthly minimum. Check that minimum against your needs before moving workloads or estimating total cost.

    Trade-off: Redis Pro has a $200 monthly minimum.

  6. Local SQL analytics

    DuckDB

    DuckDB is worth considering if you mainly use SingleStore for SQL-based data wrangling on CSV or Parquet files. Its listing describes it as a free analytical database with a free plan and no listed starting price. It is a narrower option than a mixed-workload database, so verify concurrency and support details for your use case.

    Trade-off: Verify concurrency and support details.

  7. Postgres with branching

    Neon

    Neon is an option if you want a Postgres backend, database branching and support for variable database load. Its listed starting price is $15, with a free plan. The pricing is usage-based, so estimate expected use before you migrate; the listing specifically cautions teams to budget carefully.

    Trade-off: Usage-based pricing needs careful budgeting.

Questions people ask

Which SingleStore alternative is closest for mixed workloads?

The pricing page do not identify a direct one-for-one replacement for SingleStore’s transaction-and-analytics positioning. PostgreSQL is the relational option, while ClickHouse is listed for real-time analytics over large datasets. Choose based on which part of your current workload matters most, then compare the workload against the candidate before migrating.

Is PostgreSQL a good reason to leave SingleStore?

It may be if you want an open-source relational database, need JSON support, or have a classic app workload. One Reddit user reported comparable PostgreSQL performance on their own use case, but also described differences in features and compatibility. That report is not a benchmark or a promise for your workload.

How should we compare SingleStore and alternative pricing?

SingleStore’s starting price is listed as n/a, though a free workspace is noted. The alternatives include free plans and paid starting prices, but those figures do not establish your total bill. Price the compute and storage you need for SingleStore, then compare usage, plan details and any stated minimums before switching.
