Devstral alternatives

7 tools we tested head to head against Devstral, ranked — and what each one actually does differently.

last reviewed 29 jul 2026 · from our best 8 coding llms ·list curated by Onur Ozcanx in

first — what you'd be leaving

Devstral ranks #5 of 8 in our coding llms testing. the small one is apache 2.0 and the big one stops working for you the month you pass $20m in revenue..

77/100

two models, two licences, and mistral says so plainly — which after codestral from the same company is a meaningful improvement in candour.

why people look for an alternative

−123b rights revoked above $20m monthly revenue
−hard cutoff rather than a graduated licence fee
−fill-in-the-middle support unconfirmed
−devstral 2's context length not confirmed

stay with Devstral if devstral small 24b is plain apache 2.0 is the thing you care about most — nothing below beats it on that.

Qwen3-Coder

#1 in coding llms · apache 2.0 confirmed in the licence text, a million tokens of context, and now a version small enough to actually run.

90/100

verdictthe cleanest licence and the longest context in the category, with a february variant that finally makes it deployable outside a datacentre.

DeepSeek Coder

#2 in coding llms · the brand is now an api alias — and the models behind it went from a restrictive weights licence to plain mit.

88/100

verdictthe strongest swe-bench numbers here under a licence that got more permissive rather than less — with no small variant left for anyone who wanted the original.
