The short version

  • CodeSandbox is free; TiDB starts at $250/mo.
  • Only CodeSandbox lists instant sandboxes; only TiDB lists MySQL wire compatibility.
  • Where CodeSandbox falls short: public sandboxes are visible to others by default, which is not ideal for proprietary code.
  • Prices and features on this page were last checked on 30 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

CodeSandbox

  • Running AI agent-generated code safely in isolationnot TiDB
  • Prototyping and sharing web projects in-browsernot TiDB
  • Executing untrusted code for a code playground productnot TiDB
  • Using sandboxes as ephemeral CI/CD build environmentsnot TiDB

TiDB

  • A MySQL workload that has hit the write ceiling of a single primary and would otherwise need an application-level sharding layernot CodeSandbox
  • Reporting that must run against current transactional data, where the columnar replica removes the delay and the cost of an ETL pipelinenot CodeSandbox
  • Multi-region deployments needing a single logical database with automatic failover rather than manual primary promotionnot CodeSandbox
  • Migrating off a sharded MySQL estate where the sharding logic in the application has become the main source of bugs and operational toilnot CodeSandbox

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

CodeSandbox

  • Focus has shifted toward programmatic sandbox infrastructure, which may be less approachable for casual users just wanting a quick online editor
  • Public sandboxes are visible to others by default, which is not ideal for proprietary code

TiDB

  • A production cluster needs several placement driver, storage and SQL nodes before it is fault tolerant, so the minimum viable footprint is far larger than a MySQL server and TiDB is never the economical choice for a small database
  • Every transaction takes a timestamp from the placement driver and crosses the network to storage nodes, so simple point queries are slower than on single-node MySQL and latency-sensitive paths need to be measured, not assumed
  • MySQL compatibility is at the wire and dialect level but not complete; stored procedures, triggers and events are not supported, so an application that pushed logic into the database cannot simply be repointed
  • The columnar replica is an extra full copy of the data on its own nodes, so hybrid analytics roughly doubles storage and adds hardware that must be sized and paid for separately
  • Operating it well requires cluster-specific expertise in TiUP or the Kubernetes operator, region hot spots, and rebalancing behaviour, so the licence is free but the running cost includes an engineer who understands distributed storage

Answered from the vendors’ own pages

CodeSandbox: Does CodeSandbox offer a free tier?

Yes, CodeSandbox offers a free option available on the platform. Users can start for free.

Source
TiDB: Is TiDB a drop-in replacement for MySQL?

At the protocol and dialect level it is close, and most applications connect unchanged. Stored procedures, triggers and events are not supported, and latency characteristics differ, so it needs testing rather than assumption.

CodeSandbox: Where can I find CodeSandbox's pricing details?

CodeSandbox maintains a dedicated pricing page, but specific tier names, feature breakdowns, and costs are not displayed on the landing page.

Source
TiDB: What licence is it under?

Apache 2.0, for both TiDB and the underlying TiKV storage engine. TiKV is a graduated CNCF project, which is a meaningful governance signal in a market where several competitors moved to source-available licences.

TiDB: Do I need TiFlash?

Only for analytical queries. It is an optional columnar replica; without it TiDB is a distributed transactional database. With it you get analytics on live data at the cost of an additional full copy.

TiDB: Is the managed cloud the same software?

TiDB Cloud runs the same engine, with the control plane, scaling and operational tooling provided as a service. The entry tier is metered differently from a dedicated cluster, so the cost model rather than the engine is what changes.

TiDB: When is TiDB the wrong choice?

When the database is small enough for one server, when latency on single-row lookups is the primary constraint, or when the application depends on MySQL stored procedures and triggers.
