21 <h3>The Free Software Definition</h3>
22
23 <blockquote>
24 <p>
25 The free software definition presents the criteria for whether a
26 particular software program qualifies as free software. From time to
27 time we revise this definition, to clarify it or to resolve questions
28 about subtle issues. See the <a href="#History">History section</a>
29 below for a list of changes that affect the definition of free
30 software.
31 </p>
32
33 <p>
34 &ldquo;Open source&rdquo; is something different: it has a very
35 different philosophy based on different values. Its practical
36 definition is different too, but nearly all open source programs are
37 in fact free. We explain the
38 difference <a href="/philosophy/open-source-misses-the-point.html">here</a>.
39 </p>
40 </blockquote>
41
42 <p>
43 &ldquo;Free software&rdquo; means software that respects users'
44 freedom and community. Roughly, it means that <b>the users have the
45 freedom to run, copy, distribute, study, change and improve the
46 software</b>. Thus, &ldquo;free software&rdquo; is a matter of
47 liberty, not price. To understand the concept, you should think of
48 &ldquo;free&rdquo; as in &ldquo;free speech,&rdquo; not as in
49 &ldquo;free beer&rdquo;. We sometimes call it &ldquo;libre
50 software,&rdquo; borrowing the French or Spanish word for
51 &ldquo;free&rdquo; as in freedom, to show we do not mean the software
52 is gratis.
53 </p>
54
55 <p>
56 We campaign for these freedoms because everyone deserves them. With
57 these freedoms, the users (both individually and collectively) control
58 the program and what it does for them. When users don't control the
59 program, we call it a &ldquo;nonfree&rdquo; or
60 &ldquo;proprietary&rdquo; program. The nonfree program controls the
61 users, and the developer controls the program; this makes the
62 program <a href="/philosophy/free-software-even-more-important.html">
63 an instrument of unjust power</a>.
64 </p>
65
66 <h4> The four essential freedoms</h4>
67
68 <p>
69 A program is free software if the program's users have the
70 four essential freedoms:
71 </p>
72
73 <ul>
74 <li>The freedom to run the program as you wish,
75 for any purpose (freedom 0).</li>
76 <li>The freedom to study how the program works, and change it so it
77 does your computing as you wish (freedom 1). Access to the source
78 code is a precondition for this.
79 </li>
80 <li>The freedom to redistribute copies so you can help others
81 (freedom 2).
82 </li>
83 <li>The freedom to distribute copies of your modified versions
84 to others (freedom 3). By doing this you can give the whole
85 community a chance to benefit from your changes.
86 Access to the source code is a precondition for this.
87 </li>
88 </ul>
89
90 <p>
91 A program is free software if it gives users adequately all of these
92 freedoms. Otherwise, it is nonfree. While we can distinguish various
93 nonfree distribution schemes in terms of how far they fall short of
94 being free, we consider them all equally unethical.</p>
95
96 <p>In any given scenario, these freedoms must apply to whatever code
97 we plan to make use of, or lead others to make use of. For instance,
98 consider a program A which automatically launches a program B to
99 handle some cases. If we plan to distribute A as it stands, that
100 implies users will need B, so we need to judge whether both A and B
101 are free. However, if we plan to modify A so that it doesn't use B,
102 only A needs to be free; B is not pertinent to that plan.</p>
103
104 <p>
105 &ldquo;Free software&rdquo; does not mean &ldquo;noncommercial&rdquo;. A free
106 program must be available for commercial use, commercial development,
107 and commercial distribution. Commercial development of free software
108 is no longer unusual; such free commercial software is very important.
109 You may have paid money to get copies of free software, or you may have
110 obtained copies at no charge. But regardless of how you got your copies,
111 you always have the freedom to copy and change the software, even to
112 <a href="/philosophy/selling.html">sell copies</a>.
113 </p>
114
115 <p>The rest of this page clarifies certain points about what makes
116 specific freedoms adequate or not.</p>
117
118 <h4>The freedom to run the program as you wish</h4>
119
120 <p>
121 The freedom to run the program means the freedom for any kind of person
122 or organization to use it on any kind of computer system, for any kind of
123 overall job and purpose, without being required to communicate about it
124 with the developer or any other specific entity. In this freedom, it is
125 the <em>user's</em> purpose that matters, not the <em>developer's</em>
126 purpose; you as a user are free to run the program for your purposes,
127 and if you distribute it to someone else, she is then free to run it
128 for her purposes, but you are not entitled to impose your purposes on her.
129 </p>
130
131 <p>
132 The freedom to run the program as you wish means that you are not
133 forbidden or stopped from making it run. This has nothing to do with what
134 functionality the program has, whether it is technically capable of
135 functioning in any given environment, or whether it is useful for any
136 particular computing activity.</p>
137
138 <h4>The freedom to study the source code and make changes</h4>
139
140 <p>
141 In order for freedoms 1 and 3 (the freedom to make changes and the
142 freedom to publish the changed versions) to be meaningful, you must have
143 access to the source code of the program. Therefore, accessibility of
144 source code is a necessary condition for free software. Obfuscated
145 &ldquo;source code&rdquo; is not real source code and does not count
146 as source code.
147 </p>
148
149 <p>
150 Freedom 1 includes the freedom to use your changed version in place of
151 the original. If the program is delivered in a product designed to
152 run someone else's modified versions but refuse to run yours &mdash; a
153 practice known as &ldquo;tivoization&rdquo; or &ldquo;lockdown&rdquo;,
154 or (in its practitioners' perverse terminology) as &ldquo;secure
155 boot&rdquo; &mdash; freedom 1 becomes an empty pretense rather than a
156 practical reality. These binaries are not free
157 software even if the source code they are compiled from is free.
158 </p>
159
160 <p>
161 One important way to modify a program is by merging in available free
162 subroutines and modules. If the program's license says that you
163 cannot merge in a suitably licensed existing module &mdash; for instance, if it
164 requires you to be the copyright holder of any code you add &mdash; then the
165 license is too restrictive to qualify as free.
166 </p>
167
168 <p>
169 Whether a change constitutes an improvement is a subjective matter.
170 If your right to modify a program is limited, in substance, to changes that
171 someone else considers an improvement, that program is not free.
172 </p>
173
174 <h4>The freedom to redistribute if you wish: basic requirements</h4>
175
176 <p>Freedom to distribute (freedoms 2 and 3) means you are free to
177 redistribute copies, either with or without modifications, either
178 gratis or charging a fee for distribution, to
179 <a href="#exportcontrol">anyone anywhere</a>. Being free to do these
180 things means (among other things) that you do not have to ask or pay
181 for permission to do so.
182 </p>
183
184 <p>
185 You should also have the freedom to make modifications and use them
186 privately in your own work or play, without even mentioning that they
187 exist. If you do publish your changes, you should not be required to
188 notify anyone in particular, or in any particular way.
189 </p>
190
191 <p>
192 Freedom 3 includes the freedom to release your modified versions
193 as free software. A free license may also permit other ways of
194 releasing them; in other words, it does not have to be
195 a <a href="/copyleft/copyleft.html">copyleft</a> license. However, a
196 license that requires modified versions to be nonfree does not qualify
197 as a free license.
198 </p>
199
200 <p>
201 The freedom to redistribute copies must include binary or executable
202 forms of the program, as well as source code, for both modified and
203 unmodified versions. (Distributing programs in runnable form is necessary
204 for conveniently installable free operating systems.) It is OK if there
205 is no way to produce a binary or executable form for a certain program
206 (since some languages don't support that feature), but you must have the
207 freedom to redistribute such forms should you find or develop a way to
208 make them.
209 </p>
210
211 <h4>Copyleft</h4>
212
213 <p>
214 Certain kinds of rules about the manner of distributing free
215 software are acceptable, when they don't conflict with the central
216 freedoms. For example, <a href="/copyleft/copyleft.html">copyleft</a>
217 (very simply stated) is the rule that when redistributing the program,
218 you cannot add restrictions to deny other people the central freedoms.
219 This rule does not conflict with the central freedoms; rather it
220 protects them.
221 </p>
222
223 <p>
224 In the GNU project, we use copyleft to protect the four freedoms
225 legally for everyone. We believe there are important reasons why
226 <a href="/philosophy/pragmatic.html">it is better to use
227 copyleft</a>. However,
228 <a href="/philosophy/categories.html#Non-CopyleftedFreeSoftware">
229 noncopylefted free software</a> is ethical
230 too. See <a href="/philosophy/categories.html">Categories of Free
231 Software</a> for a description of how &ldquo;free software,&rdquo;
232 &ldquo;copylefted software&rdquo; and other categories of software
233 relate to each other.
234 </p>
235
236 <h4>Rules about packaging and distribution details</h4>
237
238 <p>
239 Rules about how to package a modified version are acceptable,
240 if they don't substantively limit your freedom to release modified
241 versions, or your freedom to make and use modified versions privately.
242 Thus, it is acceptable for the license to require that you change the
243 name of the modified version, remove a logo, or identify your
244 modifications as yours. As long as these requirements are not so
245 burdensome that they effectively hamper you from releasing your
246 changes, they are acceptable; you're already making other changes to
247 the program, so you won't have trouble making a few more.
248 </p>
249
250 <p>
251 Rules that &ldquo;if you make your version available in this way, you
252 must make it available in that way also&rdquo; can be acceptable too,
253 on the same condition. An example of such an acceptable rule is one
254 saying that if you have distributed a
255 modified version and a previous developer asks for a copy of it, you
256 must send one. (Note that such a rule still leaves you the choice of
257 whether to distribute your version at all.) Rules that require release
258 of source code to the users for versions that you put into public use
259 are also acceptable.
260 </p>
261
262 <p>
263 A special issue arises when a license requires changing the name by
264 which the program will be invoked from other programs. That
265 effectively hampers you from releasing your changed version so that it
266 can replace the original when invoked by those other programs. This
267 sort of requirement is acceptable only if there's a suitable aliasing
268 facility that allows you to specify the original program's name as an
269 alias for the modified version.</p>
270
271 <h4>Export regulations</h4>
272
273 <p>
274 Sometimes government <a id="exportcontrol">export control regulations</a>
275 and trade sanctions can constrain your freedom to distribute copies of
276 programs internationally. Software developers do not have the power to
277 eliminate or override these restrictions, but what they can and must do
278 is refuse to impose them as conditions of use of the program. In this
279 way, the restrictions will not affect activities and people outside the
280 jurisdictions of these governments. Thus, free software licenses
281 must not require obedience to any nontrivial export regulations as a
282 condition of exercising any of the essential freedoms.
283 </p>
284
285 <p>
286 Merely mentioning the existence of export regulations, without making
287 them a condition of the license itself, is acceptable since it does
288 not restrict users. If an export regulation is actually trivial for
289 free software, then requiring it as a condition is not an actual
290 problem; however, it is a potential problem, since a later change in
291 export law could make the requirement nontrivial and thus render the
292 software nonfree.
293 </p>
294
295 <h4>Legal considerations</h4>
296
297 <p>
298 In order for these freedoms to be real, they must be permanent and
299 irrevocable as long as you do nothing wrong; if the developer of the
300 software has the power to revoke the license, or retroactively add
301 restrictions to its terms, without your doing anything wrong to give
302 cause, the software is not free.
303 </p>
304
305 <p>
306 A free license may not require compliance with the license of a
307 nonfree program. Thus, for instance, if a license requires you to
308 comply with the licenses of &ldquo;all the programs you use&rdquo;, in
309 the case of a user that runs nonfree programs this would require
310 compliance with the licenses of those nonfree programs; that makes the
311 license nonfree.
312 </p>
313
314 <p>
315 It is acceptable for a free license to specify which jurisdiction's
316 law applies, or where litigation must be done, or both.
317 </p>
318
319 <h4>Contract-based licenses</h4>
320
321 <p>
322 Most free software licenses are based on copyright, and there are limits
323 on what kinds of requirements can be imposed through copyright. If a
324 copyright-based license respects freedom in the ways described above, it
325 is unlikely to have some other sort of problem that we never anticipated
326 (though this does happen occasionally). However, some free software
327 licenses are based on contracts, and contracts can impose a much larger
328 range of possible restrictions. That means there are many possible ways
329 such a license could be unacceptably restrictive and nonfree.
330 </p>
331
332 <p>
333 We can't possibly list all the ways that might happen. If a
334 contract-based license restricts the user in an unusual way that
335 copyright-based licenses cannot, and which isn't mentioned here as
336 legitimate, we will have to think about it, and we will probably conclude
337 it is nonfree.
338 </p>
339
340 <h4>Use the right words when talking about free software</h4>
341
342 <p>
343 When talking about free software, it is best to avoid using terms
344 like &ldquo;give away&rdquo; or &ldquo;for free,&rdquo; because those terms imply that
345 the issue is about price, not freedom. Some common terms such
346 as &ldquo;piracy&rdquo; embody opinions we hope you won't endorse. See
347 <a href="/philosophy/words-to-avoid.html">Confusing Words and Phrases that
348 are Worth Avoiding</a> for a discussion of these terms. We also have
349 a list of proper <a href="/philosophy/fs-translations.html">translations of
350 &ldquo;free software&rdquo;</a> into various languages.
351 </p>
352
353 <h4>How we interpret these criteria</h4>
354
355 <p>
356 Finally, note that criteria such as those stated in this free software
357 definition require careful thought for their interpretation. To decide
358 whether a specific software license qualifies as a free software license,
359 we judge it based on these criteria to determine whether it fits their
360 spirit as well as the precise words. If a license includes unconscionable
361 restrictions, we reject it, even if we did not anticipate the issue
362 in these criteria. Sometimes a license requirement raises an issue
363 that calls for extensive thought, including discussions with a lawyer,
364 before we can decide if the requirement is acceptable. When we reach
365 a conclusion about a new issue, we often update these criteria to make
366 it easier to see why certain licenses do or don't qualify.
367 </p>

369 <h4>Get help with free licenses</h4>
370
371 <p>
372 If you are interested in whether a specific license qualifies as a free
373 software license, see our <a href="/licenses/license-list.html">list
374 of licenses</a>. If the license you are concerned with is not
375 listed there, you can ask us about it by sending us email at

377 </p>
378
379 <p>
380 If you are contemplating writing a new license, please contact the
381 Free Software Foundation first by writing to that address. The
382 proliferation of different free software licenses means increased work
383 for users in understanding the licenses; we may be able to help you
384 find an existing free software license that meets your needs.
385 </p>
386
387 <p>
388 If that isn't possible, if you really need a new license, with our
389 help you can ensure that the license really is a free software license
390 and avoid various practical problems.

392
393 <h3 id="beyond-software">Beyond Software</h3>
394
395 <p>
396 <a href="/philosophy/free-doc.html">Software manuals must be free</a>,
397 for the same reasons that software must be free, and because the
398 manuals are in effect part of the software.
399 </p>
400
401 <p>
402 The same arguments also make sense for other kinds of works of
403 practical use &mdash; that is to say, works that embody useful knowledge,
404 such as educational works and reference
405 works. <a href="http://wikipedia.org">Wikipedia</a> is the best-known
406 example.
407 </p>
408
409 <p>
410 Any kind of work <em>can</em> be free, and the definition of free software
411 has been extended to a definition of <a href="http://freedomdefined.org/">
412 free cultural works</a> applicable to any kind of works.
413 </p>
414
415 <h3 id="open-source">Open Source?</h3>
416
417 <p>
418 Another group uses the term &ldquo;open source&rdquo; to mean
419 something close (but not identical) to &ldquo;free software&rdquo;. We
420 prefer the term &ldquo;free software&rdquo; because, once you have heard that
421 it refers to freedom rather than price, it calls to mind freedom. The
422 word &ldquo;open&rdquo; <a href="/philosophy/open-source-misses-the-point.html">
423 never refers to freedom</a>.
