falkordb/falkordb: technical due diligence, read from its repository
What Borehole read in falkordb/falkordb's code and history at a477d9a: its licence, security advisories, releases, review practice, tests, dependencies and operations. Every finding cites the file and line it rests on. The full report also covers the team and asks the questions the code cannot answer.

LICENSE:1: The licence is SSPL-1.0 with additional terms: source available, not open sourceLICENSE: Relicensed: AGPL-3.0 → Apache-2.0 with the Commons Clause and an attribution term (2018-07-16) → RSALv2 (2019-02-21) → SSPL-1.0 (2022-11-15) → SSPL-1.0 with additional terms (2023-08-11).gitmodules:1: 3 submodule(s) this survey does not read: deps/RediSearch, deps/GraphBLAS, deps/LAGraph
Architecture & Codebase — including AI provenance
stronggraph/src/graph/graphblas/mod.rs is 17,073 lines, 85× this codebase's median file
adequateThe median source file here is 200 lines. 18 files exceed 2,000 lines, the largest being 17,073. Size is not a defect on its own — some problems genuinely live in one place — but these are where merge conflicts, review fatigue and single-owner knowledge concentrate, and they are the first thing that slows an inheriting engineer down.

Engineering Process & SDLC Maturity
adequate7% of recent commits change more than 2,000 lines
adequate38 of 517 commits in the last 24 months changed over 2,000 lines of code, not counting reformatting, renames, vendored or generated code. A change that size is rarely reviewed line by line. Ask how they were reviewed, and what made them that large.

Product & Engineering Maturity
strongReleases are cut from another branch than the one surveyed
adequateThe newest release, v6.0.3, is not on the branch this survey read; the newest release on it is v1.99.7. The shipped product may differ from what this report describes. Survey the release branch too.

Security & Reliability Posture
strong2 locked dependencies have published vulnerabilities
adequate2 of 216 locked dependencies match 2 published advisories in OSV. A lockfile says which version is installed, not whether the flawed code is reachable from this product, so each needs a look. Most are fixed by an upgrade, and the advisory names the version. This lockfile pins development tools alongside what ships and does not say which is which, so some of these may never reach a user.
Cargo.lock — orx-split-vec 3.23.0: RUSTSEC-2026-0252 (unrated), fixed in 4.0.0 |
Cargo.lock — rustls-webpki 0.103.15: RUSTSEC-2026-0382 (unrated), fixed in 0.103.16 |
1 vendored component with no licence
adequateThird-party code is committed into this repository without any statement of the terms it arrived under. Unknown terms are harder to deal with than inconvenient ones: an awkward licence can be complied with, an absent one cannot. Each of these needs its origin established before the code changes hands.
deps/native-deps.lock — 1 tracked files, no licence file |
The licence is SSPL-1.0 with additional terms: source available, not open source
adequateLICENSE grants SSPL-1.0 with additional terms: source available, not open source; offering it as a service obliges publishing the whole service stack. The reading comes from the licence's own title and clauses. Whether the terms fit the buyer's intended use, and whether any paid licence transfers with the code, is a question for counsel and the licensor.
LICENSE:1 — 655 lines, SSPL-1.0 AND LicenseRef-Terms-Additional |
Relicensed: AGPL-3.0 → Apache-2.0 with the Commons Clause and an attribution term (2018-07-16) → RSALv2 (2019-02-21) → SSPL-1.0 (2022-11-15) → SSPL-1.0 with additional terms (2023-08-11)
adequateThe root licence changed 4 time(s). The latest terms restrict what users, hosts or a buyer may do in ways the earlier ones did not. Code taken under the old terms stays under them, so both matter in diligence.

15 advisories against this project in the last 24 months, 13 high or critical
adequateThe newest was published on 2026-10-09. A project that publishes advisories is telling its users about its fixes, and the count and pace say how much security work it carries. Whether 8 of them are fixed in the code you ship could not be told from this history: its version is only known to be at least 1.99.7. Answer lives in: the release you run, set against each fixed version. The record is incomplete: NVD: 1 record names falkordb with nothing tying it to this repository (CVE-2026-114510).
