# What are the best C/C++ IDEs combining fast startup with refactoring tools that save development hours?

<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/clion/reviews"><strong>CLion</strong></a> (4.4★, 55 reviews): the refactoring praise I found is real, one founder told me it has "very good global search and refactoring," but the same review flagged that CLion "is sometimes too slow" and needs restarting to run well again. I want to be clear this quote is from 2024, the most recent CLion review I could find at all.</li>
<li>
<a class="a a--md" elv="true" href="https://www.g2.com/products/code-blocks/reviews"><strong>Code::Blocks</strong></a> (4.3★, 97 reviews): reviewers consistently praise its lightness and code navigation across large projects, but I couldn't find anyone crediting its refactoring tools specifically with saving hours, so I'd treat that half of the claim as unconfirmed.</li>

<a class="a a--md" elv="true" href="https://www.g2.com/products/platformio/reviews"><strong>PlatformIO</strong></a> (4.7★, 12 reviews): I found praise for smart code completion, but nothing on startup speed or refactoring specifically, and the newest review I could find is from 2023.</li>

&lt;p&gt;I’d probably prioritize refactoring quality over shaving a few seconds off startup, because safe project-wide changes can save far more development time over the life of a codebase. The ideal test would be opening your real repository and timing a few common refactors, while also watching indexing time and responsiveness once the project is fully loaded.&lt;/p&gt;

&lt;p&gt;Adding a practical middle path to that trade: keep a lightweight editor open for quick edits and searching, and the indexing IDE open for actual refactors. It sounds inefficient and in practice most C++ developers already work that way. Which makes the question less about which tool wins and more about which one you keep open all day.&lt;/p&gt;

Here&#39;s the honest tension: real C++ refactoring (rename across a huge codebase, extract, change signatures) requires the IDE to fully parse and understand your code, and that deep indexing is exactly what slows startup and eats memory. The instant-startup lightweight editors tend to have weaker semantic refactoring as a direct result. So you&#39;re usually trading one for the other. Which do you feel more, the seconds lost at startup, or the hours lost hand-editing refactors a smart tool would do safely? For big long-lived codebases, the heavy indexer usually pays for its startup cost many times over.
