2. 1. Acronym Plays (COSS alternatives)
| Acronym | Expansion | Verdict |
|---|---|---|
| MOSS | Managed Open Source Studio / Modern Open Source Software | Good. Moss grows everywhere, quietly, without permission. Perfect metaphor for OSS. moss.so or moss.dev would be great. |
| ROSS | Revenue Open Source Software / Revenue-first OSS | Interesting -- puts "revenue" first, which is honest about the commercial angle. ross.dev. Also just a name, which is humanizing. |
| GOSS | Group of Open Source Software | Bad connotation (gossip). Skip. |
| BOSS | Business Open Source Studio | Memorable but reads as arrogant rather than principled. Pass. |
| TOSS | -- | No. |
| DOSS | Distributed Open Source Studio | Too close to "dossier" in French, which is actually fine. But sounds like "doze." Skip. |
| HOSS | Holding of Open Source Software | Honest acronym. Sounds like a large person. Mildly charming. |
| VOSS | Ventures in Open Source Software | Voss is a water brand. Not ideal. |
| NOSS | Network of Open Source Studios | Sounds like "gnosis" if you squint. Probably not the right association. |
| SOSS | Studio of Open Source Software | Sounds like a condiment. Skip. |
| FOSS Capital | Free and Open Source -- but commercial | Subverting FOSS by adding "Capital" is provocative and honest. FOSS Capital already exists (the fund). Avoid as a name. |
| ORCA | Open Revenue Commercial Alliance | Stretch acronym but orca is a great animal. Dominant, intelligent, works in groups. orca.dev. |
| ARC | Applied Revenue through Code / Architectural Revenue Co | Clean, three letters, architectural meaning. arc.dev is taken but arc.so is the browser. Still a beautiful word. |
3. 2. French Words That Work in English
The advantage of being French: there is a whole language of elegant, short words that most English speakers find sophisticated rather than confusing. Used well, a French name for a holding company signals taste. Used poorly, it signals pretension. The test: can an English speaker read it, say it approximately correctly, and not feel stupid?
| Name | Meaning | Verdict |
|---|---|---|
| Ouvert | "Open" in French | Perfect. One word, says everything, sounds professional, easy for English speakers (oo-VAIR). Ouvert.co. Top pick. |
| Libre | "Free" (as in freedom) in French/Spanish | Already deeply associated with the OSS movement (LibreOffice, libre software). Can work as a company name if paired: Libre Holdings, Libre Studio. libre.co. |
| Source | Same in both languages | Too generic alone. But as a proper noun for a holding company it has weight. source.dev is taken. source.co might work. |
| Noyau | "Kernel" or "core/nucleus" in French | Brilliant for OSS -- le noyau is literally the Linux kernel in French. noyau.io. Hard for English speakers to pronounce (nwah-YO) but memorable once learned. High signal for anyone who gets the reference. |
| Racine | "Root" in French (also the famous playwright) | Strong. OSS is all about roots. racine.dev or racine.io. English speakers can say it (rah-SEEN). Also carries the weight of French classical culture. |
| Socle | "Foundation" or "pedestal" or "base" in French | Underused, powerful word. The socle is what everything rests on. socle.io. Short, professional, almost unknown outside France which makes it ownable. |
| Atelier | "Workshop" or "studio" in French | Already used in tech (Atelier Ventures, etc.) but the word is great. atelier.dev. Has craft energy. Slightly too artisanal for a holding company. |
| Ensemble | "Together" in French | Multiple companies, one direction. Ensemble Holdings. ensemble.co. Very French, very collaborative. |
| Communs | "The Commons" in French (les communs) | Deeply philosophical -- "les communs numériques" is a real French political and economic concept (digital commons). communs.co. Smart and principled positioning. |
| Partage | "Sharing" in French | OSS is about sharing code. partage.io. Sounds clean in English (par-TAZH). Warm concept. |
| Fonderie | "Foundry" in French | Historical French industrial companies were often "Forges et Fonderies de X." A foundry makes things. fonderie.io. Craft and industrial history in one word. |
| Pilier | "Pillar" in French | Structural, supporting, essential. pilier.io. Short and strong. |
| Levier | "Lever" in French | Leverage is the holding company model. levier.co. Business-minded and precise. |
| Moteur | "Engine" in French | The engine behind multiple products. moteur.io. Has drive and momentum. |
| Branche | "Branch" in French (also Git branch) | Double meaning with Git. branche.dev. Works in both languages without translation. |
| Cœur | "Heart" or "core" in French | Coeur.io or coeur.co. Elegant. "Core" in French with an emotional resonance. Hard to type (the ligature). |
| Tronc | "Trunk" in French (tree trunk, also the main branch) | Both arboreal and Git. tronc.dev. Blunt, short, developer-friendly. Slightly ungainly in English though. |
| Pivot | Same in French and English | Every holding company pivots. But "pivot" is a startup cliche now. Skip. |
| Agora | Greek, used in French -- the public square | Open source is a public square for code. agora.dev. Ancient and democratic. Strong. |
| Forum | Latin/French -- the public meeting place | Same idea as agora, even more classic. forum.co is probably taken. But Forum Holdings has weight. |
| Portail | "Portal" in French | The entry point. portail.io. Too website-y for a holding company. |
4. 3. Latin and Greek Roots
Latin is the shared ancestor of French, and much of the OSS vocabulary is Latin-rooted (liber, communis, apertus). These names work in both French and international contexts and carry a sense of permanence.
| Name | Root / Meaning | Verdict |
|---|---|---|
| Apertus | Latin: "open, uncovered" | The Latin root of "aperture." Apertus Holdings. apertus.io. Precise, intellectual, signals open without saying it. |
| Apertura | Latin/Italian: "opening" | Softer than Apertus. apertura.co. Works across Romance languages. |
| Liber | Latin: "free" (free software = logiciel libre) | Direct root of "liberty" and "library." Liber Capital, Liber Holdings. liber.co. Elegant and principled. |
| Communis | Latin: "shared, common, public" | Root of "community." communis.io. Slightly academic but serious. |
| Fons | Latin: "source, spring, origin" | The spring that feeds a river. "Source" in its oldest form. fons.io. Short and mythic. |
| Fontis | Latin genitive of Fons: "of the source" | fontis.io. Slightly more brandable than Fons. |
| Nexus | Latin: "connection, link, bond" | Multiple OSS companies connected at the holding level. nexus.dev. Probably taken (Sonatype Nexus Repository). Strong word though. |
| Vertex | Latin: "highest point, apex" | The holding company above all the products. vertex.io. Taken as a Google Cloud product. Still a strong word. |
| Lucet | Latin: "it shines, it is clear" | Open source = transparent. lucet.io. Short, unusual, memorable. |
| Aperto | Italian: "open" | Italian sibling to Apertus, more casual. aperto.io. Clean. |
| Phalanx | Greek: "tight formation, unified force" | Multiple companies moving together. Aggressive but memorable. phalanx.io. |
| Agora | Greek: "public assembly place" | The open square where everyone gathers. agora.dev. Democratic. Open source is agora-coded. |
| Logos | Greek: "word, reason, logic" | The underlying logic of open source. logos.dev. Has philosophy. Probably too religious in some contexts. |
| Telos | Greek: "end, goal, purpose" | The purpose of open source. telos.co. Philosophical holding company name. |
| Arche | Greek: "origin, beginning, principle" | arche.io. Where things begin. First principles energy. Top pick in this category. |
| Pragma | Greek: "action, deed" (root of "pragmatic") | Commercial open source is pragmatic idealism. pragma.io. pragma.dev. Developer-friendly, sounds like a package manager. |
| Stoa | Greek: "covered walkway, porch" (origin of Stoicism) | The Stoics met in a stoa. Philosophy that is also architecture. stoa.io. Short and unusual. |
| Tekton | Greek: "builder, craftsman" | Also a Kubernetes CI/CD tool. Avoid in developer spaces. |
5. 4. The Forge Tradition
"La forge" is a very French concept -- forges and foundries were the backbone of French industrial history ("Les Forges de X" is a classic French company naming pattern). It also maps perfectly to software: you forge products. And SourceForge, despite its age, made this word famous in OSS. The forge tradition deserves its own category.
| Name | Angle | Verdict |
|---|---|---|
| LaForge | The foundry, the workshop. Also Geordi La Forge from Star Trek. | Charming. French, recognizable, has a famous fictional engineer attached. laforge.dev. Strong candidate. |
| Forge | Pure, simple | forge.dev or forge.io are almost certainly taken. But as a brand Forge is clean. Forge Holdings. |
| Forgehub | Hub for forged products | forgehub.io. Functional. |
| Forgegroup | Group of forges | Forgegroup.io. Corporate but clear. |
| Forgeco | Forge + company | forgeco.io. Short and clean. |
| Openforge | Combines open + forge | openforge.dev. Probably taken in some form but worth checking. |
| Softforge | Software forge | softforge.io. Functional but a bit 2003. |
| Codeforge | Forge of code | codeforge.io. Taken in many forms. |
| Freeforge | Free + forge | freeforge.dev. freeforge.io. Nice energy. |
| Libreforge | Libre + forge | libreforge.io. Very on-brand for French OSS. Rolls off the tongue if you speak French. |
| Fonderie | French: foundry (the bigger version of a forge) | fonderie.io or fonderie.co. More industrial, more French. La Fonderie. |
| La Fonderie | The foundry, with the definite article | Very French. Could shorten to Fonderie in international contexts. lafonderie.io. |
6. 5. Nature and Architecture Metaphors
| Name | Metaphor | Verdict |
|---|---|---|
| Archipel | French: archipelago -- a group of islands | Multiple independent companies (islands) under one holding. Each one self-sufficient, all related. archipel.io. Top pick. Very French, very elegant. |
| Archipelago | English version | Too long. Archipel is better. |
| Constellation | Group of stars, each shining independently | Poetic. Constellation Holdings is already a common name. constellation.dev. |
| Canopy | The top layer of the forest -- covers everything below | The holding company as the canopy over multiple OSS projects. canopy.io. Elegant. Used in some VC fund names already. |
| Overstory | The tall trees that form the forest canopy | Beautiful book reference (Richard Powers). overstory.io. Long but memorable. |
| Watershed | The area that drains to a common point -- all rivers lead here | Multiple products, one holding. watershed.io is taken (climate VC). Strong word. |
| Confluence | Where rivers meet | Taken by Atlassian. Avoid. |
| Tributary | A stream that feeds the main river | Each OSS company feeds the holding. tributary.io. Long. |
| Massif | French: a compact mountain mass | Very French (Massif Central). massif.io. Short, geological, solid as a rock. Unusual in tech. |
| Socle | The stone base everything rests on | Repeated from the French section because it is that good. socle.io. |
| Substrate | The underlying layer | substrate.io. Developer-friendly. The foundation under the products. |
| Bedrock | The deepest layer, solid foundation | Taken by AWS Bedrock. Skip. |
| Aquifer | Underground water source that feeds everything above | The hidden resource that makes everything work. aquifer.io. Unusual and memorable. |
| Colline | French: a hill -- smaller than a mountain, not pretentious | colline.io. Understated. Very French. |
| Sommet | French: summit, peak | The top. sommet.io. Strong and French. |
| Arbre | French: tree (direct riff on Linktree-style naming) | arbre.io. Fits the tree theme. Could be the holding company that owns Linkgrove and others. |
| Forêt | French: forest | foret.io (without accent). Multiple trees (products) in one forest (holding). foret.io is clean. |
| Berge | French: riverbank, a slope along water | berge.io. Understated. Geographic without being obvious. |
7. 6. Compound Names
| Name | Construction | Verdict |
|---|---|---|
| OpenHold | Open + Holding company | Literal but clean. openhold.co. Does exactly what it says. |
| LibreHold | Libre + Hold | librehold.io. French-flavored, direct. |
| SourceGroup | Source + Group | sourcegroup.io. Corporate but clear. |
| OpenGroup | Open + Group | Already a real standards organization. Avoid. |
| CommonStack | Common + Stack | commonstack.io. Has a technical energy. |
| Commonhold | Common + Hold | Actually a UK legal term for property co-ownership (commonhold tenure). That makes it perfect -- it is literally a shared ownership structure. commonhold.io. |
| Sourceware | Source + -ware | sourceware.org is taken (GNU). Skip. |
| Corehold | Core + Hold | corehold.io. Solid. The core of the holding company. |
| Coreworks | Core + Works | coreworks.io. Factory / studio energy. |
| Openworks | Open + Works | openworks.io. Works in both senses: "it works" and "a body of work." |
| Sourceworks | Source + Works | sourceworks.io. Same energy. |
| Librestack | Libre + Stack | librestack.io. Stack of libre products. |
| Freecode | Free + Code | freecode.com is taken (was Freshmeat). Skip. |
| Codecommuns | Code + Communs (French commons) | codecommuns.io. Very French OSS. codecommuns.fr would be natural. |
| OpenCommons | Open + Commons | opencommons.org probably taken. Good concept. |
| Softcommons | Software + Commons | softcommons.io. Interesting. |
| Pragma | Greek root for "action" -- also short for pragmatic | pragma.io or pragma.dev. Pragmatic commercial OSS. Clean and technical. |
| Praxis | Greek: practice, application of theory | Commercial OSS is OSS theory put into practice. praxis.io. Philosophical but grounded. |
| Ouvert.co | French "open" as a domain | ouvert.co. Beautiful. Short. Immediately meaningful to French speakers, intriguing to everyone else. |
8. 7. Top Picks
| Rank | Name | Why | Domain |
|---|---|---|---|
| 1 | Ouvert | French for "open." One word. No explanation needed for anyone who speaks a Romance language. Sounds professional, international, and principled. Easy enough for English speakers (oo-VAIR). The name of the holding company is its mission statement. | ouvert.co / ouvert.io |
| 2 | Archipel | An archipelago is a group of islands, each self-sufficient, all part of the same geographic family. Perfect for a holding company: each OSS company is an island. Very French (the French use "archipel" naturally), works internationally. Archipel Holdings. | archipel.io / archipel.co |
| 3 | Socle | French for "the base, the foundation, the pedestal that everything rests on." Almost unknown outside France, which means it is ownable. Short. Serious. Signals that you are the infrastructure beneath other companies. socle.io. | socle.io / socle.co |
| 4 | LaForge | The French foundry tradition + Geordi La Forge (Star Trek's chief engineer -- the person who makes everything work). A holding company that forges OSS products. French enough to feel specific, international enough to travel. laforge.dev. | laforge.dev / laforge.io |
| 5 | Arche | Greek for "origin, first principle, the beginning." The arche of open source. Short, clean, has depth. arche.io sounds like a real company. Works in French too (arche = arch, also Noah's ark -- built to survive anything). | arche.io / arche.co |
| 6 | Racine | French for "root." Also Jean Racine, the greatest French playwright after Moliere -- so it carries cultural weight in France. OSS lives by its roots. Racine Holdings. racine.io. English speakers can say it (rah-SEEN). | racine.io / racine.co |
| 7 | Noyau | French for "kernel" -- literally what the Linux kernel is called in French (le noyau Linux). A holding company named after the kernel of OSS. High signal for anyone who knows. Slightly hard to pronounce for non-French speakers (nwah-YO) but extremely memorable once learned. | noyau.io / noyau.co |
| 8 | Communs | French for "the commons" (les communs numériques is a real French political concept for digital public goods). A holding company positioned as the steward of digital commons, monetized responsibly. Communs Holdings. communs.co. | communs.co / communs.io |
| 9 | Pragma | Greek root for "action, practice." Commercial open source is pragmatic idealism -- you believe in libre software and you also need to make money. Pragma captures that tension perfectly. pragma.io. Sounds like a developer tool which is a feature. | pragma.io / pragma.dev |
| 10 | Massif | French for a compact mountain mass (like the Massif Central). Solid, geological, French, and completely unused in tech. A holding company as a massif -- immovable, foundational, a landscape feature. massif.io. | massif.io / massif.co |
The final answer
If this is a French-founded, internationally-operating commercial open source holding company, the name is Ouvert.
It is the most direct, most ownable, and most meaningful name on this list. It does not need a subtitle. It does not need an explanation to anyone who has taken a week of French. And for English speakers, "Ouvert" sounds like a European company that knows exactly what it is doing -- which is exactly the impression a French founder building serious OSS infrastructure should want to make.
The runner-up is Archipel -- for when you want the name to evoke the structure (multiple independent companies) rather than the mission (open). Both are correct. It depends on whether you want to lead with the what or the how.
