FIXED SCOPEone-off build
Ship a clean open source project.
A defined scope, a fixed price, a senior-only team. From audit to clean SBOM in 6–10 weeks.
FIXED SCOPE
- Zero juniors on client work
- Fixed quote in week 1
- Code, governance, runbook — yours
Open source developmentservices, done right.
Every modern stack runs on open source. The question is whether anyone on your team is tracking the 200 transitive dependencies that shipped last Tuesday. We provide open source development services with the governance and security discipline that keeps your dependencies from becoming your biggest liability.
- SBOM-first
- License-compliant
- CVE-monitored
- Zero abandoned deps
Why Entalogics for open source
Four things every
open source project
actually needs.
81% of audited codebases have high-risk vulnerabilities. 68% have license conflicts. Those aren't edge cases — that's the open source development default when nobody owns governance. We make sure your project isn't part of that statistic.
Security01
Every dependency is an attack surface you inherited.
SBOM generated from day one, CVE databases monitored continuously, patching enforced before it waits for someone to read a security advisory. Open source development company discipline — not hopeful reviewing.
Licensing02
License compliance — not legal's problem. It's architecture.
GPL in a proprietary binary is a lawsuit waiting for a trigger. License conflicts caught in CI and policies built into the pipeline — not discovered in a quarterly spreadsheet six months after the dependency landed.
Maintenance03
Dead dependencies are ticking clocks.
79% of codebases contain libraries with zero activity in two years. We identify abandoned open source components early and replace them before they become the vulnerability nobody can fix because the maintainer disappeared.
Type safety04
Typed wrappers around untyped community code.
Critical dependencies wrapped in typed interfaces so swapping a library touches one adapter — not fifty files scattered across the codebase. Open source development that survives the next upstream breaking change.
When open source, when not
Open source development is a tool.
Not a shortcut.
Using open source well requires more discipline than building from scratch. We'll tell you honestly where it accelerates your product and where it introduces risk you shouldn't carry.
LEAN INTO OPEN SOURCE DEVELOPMENT WHEN
- The project is mature with an active security response — PostgreSQL, Linux, Redis, React
- The library solves a problem you have no competitive reason to solve yourself
- You have the governance in place to track, update, and audit what actually ships
BE CAUTIOUS WHEN
- Fewer than two active maintainers and no corporate backing — that's a fork waiting to happen
- A copyleft license meets a proprietary product — the boundary has to be airtight
- You're pulling an entire framework for one utility function you could write in an afternoon
WE SAY NO WHEN
- "Use whatever has the most GitHub stars." Popularity isn't a security audit.
- "We'll sort licensing out later." Later is always a legal letter, not a calendar reminder.
- "We forked it and we'll maintain it ourselves." You won't. Nobody does.
What we build with open source
Six open source development
surfaces. One quality bar.
Where open source engineering shows up most in our work — each with security governance and license compliance built in from the first commit, not the last.

Full-stack open source platforms
Full-stack open source platformsNext.js, Django, Rails, Spring Boot — production platforms with dependency governance, SBOM generation, and vulnerability scanning wired in before the first deploy.

The playbook
Open source development patterns
we ship on repeat.
Governance built into every open source development engagement — not compliance checklists copied from a blog post.
P01
SBOM from day one
Every project generates a Software Bill of Materials on every build. You know what shipped, which version, and under which license — before anyone asks during due diligence.
P02
License policy in CI
GPL in a proprietary codebase fails the build, not a quarterly review six months after the dependency was quietly added to the lockfile.
P03
CVE monitoring in real time
Snyk, Trivy, or Grype runs on every pull request and on a scheduled cron. Critical CVEs trigger an alert, not a Jira ticket that sits for three sprints.
P04
Dependency health scoring
Every new open source dependency evaluated on maintainer count, release cadence, and license compatibility before it enters the lockfile at all.
P05
Typed dependency boundaries
Critical libraries wrapped in internal interfaces so swapping one library touches one adapter. The rest of the codebase doesn't know or care what changed underneath.
P06
Fork discipline
When a fork is unavoidable, it stays rebased against upstream with automated conflict detection. Forks that drift become liabilities — we don't let them.
Signature case
A fintech platform,
cleaned from 340 CVEs to a green SBOM.
A B2B fintech preparing for acquisition — 340 unpatched CVEs, 12 license conflicts including GPL in proprietary code, 47 abandoned libraries. Triaged by exploitability, patched critical paths, delivered a clean SBOM in 6 weeks. Acquisition closed on schedule.
Before
340 CVEs · 12 license conflicts · 47 abandoned deps · no SBOM · due diligence blocked
After
0 critical CVEs · 0 license conflicts · all deps maintained · full SBOM · due diligence cleared
- Critical CVEs resolved−100%
- License conflicts−100%
- To fully remediated6wk
- Acquisition delay0 days
Engagement shape
Six to ten weeks
to a clean open source codebase.
Every open source development engagement starts with an audit. What ships at the end is a codebase where every dependency is tracked, licensed, and patched — not just scanned.
- W01
Audit + RFC
Two senior open source engineers go through the entire dependency tree — SBOM generation, CVE triage, license conflict mapping, abandoned dep inventory. A ranked remediation plan with real priorities, not a raw scan dump.
- W02–03
Critical path first
Highest-risk CVEs patched, license conflicts resolved, SBOM pipeline wired into CI. Real governance in your build before the end of week three, not a report sitting in someone's inbox.
- W04–08
Remediate by priority
Dependency by dependency — abandoned libraries replaced, outdated versions upgraded, typed wrappers added around volatile open source APIs. Your team keeps shipping the entire time.
- W09+
Cleanup + handoff
Clean SBOM. License policy running in CI. CVE monitoring on autopilot. Runbook handed to your team — or we stay on retainer.

FAQ
Sharp questions,
straight answers.
License conflicts, CVE triage, dependency tooling — the questions we get on every open source development call.Every dependency's license gets scanned in CI, not after the fact. When we find a conflict, we either replace the dependency, isolate it behind a process boundary, or flag it for legal with a concrete recommendation — not a vague warning. Zero open source license conflicts in the lockfile at all times is the standard we hold.
Exploitability over severity score. A critical CVE in a dev-only dependency ranks lower than a medium CVE in a library handling user input on every request. We triage against your actual runtime and fix in order of real blast radius, not the number on a dashboard.
Renovate for most teams — more configurable, supports monorepos, groups related updates so you're not reviewing fifty PRs. Dependabot if you're GitHub-native and want zero configuration. Either way, automated open source dependency updates are non-negotiable for any production codebase.
Yes. The engineers who triage the dependency tree are the ones remediating it — no handoff mid-engagement, no account manager between you and the people doing the actual work.
Yes. GitHub Actions, GitLab CI, Jenkins, CircleCI, Azure DevOps — we integrate into your pipeline instead of asking you to rebuild it around our preferences.
