FullStackBench: Multilingual benchmark for evaluating LLMs in full-stack coding. See the comparison table for live GitHub stats and shared categories. ### When should I choose cceval over FullStackBench? Choose cceval over FullStackBench when Tags unique to cceval: benchmark, code-completion, cross-file, evaluation-tool; You need to evaluate the performance of cross-file code completion systems that can handle multiple programming languages simultaneously; More GitHub stars (182 vs 121) - visibility, not fit. ### When should I choose FullStackBench over cceval? Choose FullStackBench over cceval when Tags unique to FullStackBench: benchmarks, full stack coding, llm-evaluation; When you need to assess LLM performance in full-stack programming tasks covering multiple domains and languages; Leaner open-issue backlog (1). ### When should I avoid cceval? Your evaluation needs are focused solely on single-file or intralingual code completion benchmarks You require real-time data access or live updates; cceval provides pre-packaged datasets that need to be manually obtained and uncompressed ### When should I avoid FullStackBench? Avoid if testing scope is limited to a single or few programming languages as FullStackBench covers a wide range of languages Not suitable if your focus is solely on theoretical coding challenges instead of practical, full-stack tasks ### Is cceval or FullStackBench more popular on GitHub? cceval has more GitHub stars (182 vs 121). Stars measure visibility, not whether either tool fits your constraints. ### Are cceval and FullStackBench open source? Yes - both are open-source projects on GitHub (cceval: Apache-2.0, FullStackBench: Apache-2.0). ### Where can I find alternatives to cceval or FullStackBench? GraphCanon lists graph-backed alternatives at [cceval alternatives](/tools/amazon-science-cceval/alternatives) and [FullStackBench alternatives](/tools/bytedance-fullstackbench/alternatives) ([cceval markdown twin](/tools/amazon-science-cceval/alternatives.md), [FullStackBench markdown twin](/tools/bytedance-fullstackbench/alternatives.md)), ranked by typed relationship edges rather than popularity votes. ### Is there a machine-readable version of this comparison? Yes. The markdown twin at [this comparison](/compare/amazon-science-cceval-vs-bytedance-fullstackbench.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, cceval or FullStackBench? cceval: Slowing. FullStackBench: Dormant. Compare maintenance labels, days since push, and release cadence in the trust section below - stars alone do not measure maintenance. ### Where are the full trust reports for cceval and FullStackBench? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [cceval trust report](/tools/amazon-science-cceval/trust); [FullStackBench trust report](/tools/bytedance-fullstackbench/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=amazon-science-cceval`](/api/graphcanon/graph?tool=amazon-science-cceval) - LLM index: [/llms.txt](/llms.txt) - Full corpus: [/llms-full.txt](/llms-full.txt) _GraphCanon - The knowledge graph for AI development. https://www.graphcanon.com/_
