A good overview is written here &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;sqlsync.dev&amp;#x2F;posts&amp;#x2F;stop-building-databases&amp;#x2F;&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;sqlsync.dev&amp;#x2F;posts&amp;#x2F;stop-building-databases&amp;#x2F;&lt;/a&gt;&lt;p&gt;The essence of the approach is that a large majority of FE apps have constructed quite complex caching layers to improve performance over &amp;quot;querying backend data&amp;quot; - take a look at things like Next.js or React Query &amp;lt;- as the post above mentions, they&amp;#x27;re essentially rebuilding databases. So instead this approach just moves the db to the browser, along with a powerful syncing layer.&lt;p&gt;I think it&amp;#x27;s an approach that deserves more attention, especially to improve DX where we end up writing a whole lot of database-related logic on clients. Mind as well then just use a database on the client as well</text><parent_chain><item><author>xnorswap</author><text>I don&amp;#x27;t understand these &amp;quot;DB in browser&amp;quot; products.&lt;p&gt;If the data &amp;quot;belongs&amp;quot; to the server, why not send the query to the server and run it there?&lt;p&gt;If the data &amp;quot;belongs&amp;quot; on the client, why have it in database form, particularly a &amp;quot;data-lake&amp;quot; structured db, at all?&lt;p&gt;A lot of the benefits of such databases are their ability to optimise queries for improving performance in a context where the data can&amp;#x27;t fit in memory (and possibly not even on single disks&amp;#x2F;machines), as well as additional durability and atomicity improvements.
